How the Geosphere Interacts with Earth's Systems Welcome to Earth's Systems! Today we'll explore how the geosphere interacts with other Earth systems The geosphere is the solid part of Earth, including rocks and minerals Can you name the other main systems of Earth? (Hint: There are 3 more!)  Earth's Four Main Systems Geosphere: The solid Earth (rocks, minerals, soil) Hydrosphere: All water on Earth Atmosphere: The air around Earth Biosphere: All living things on Earth How do you think these systems might interact with each other? What is the Geosphere? The geosphere includes Earth's crust and mantle It's made up of rocks, minerals, and soil The geosphere can be solid or molten (melted) What are some things you can see that are part of the geosphere?  Geosphere and Atmosphere: Wind Erosion Wind (part of the atmosphere) can shape rocks over time This process is called wind erosion It creates unique rock formations like arches and pillars Can you think of other ways wind might change the land? Geosphere and Hydrosphere: Water Erosion Water (part of the hydrosphere) can also shape the land Rivers can carve deep canyons over millions of years Waves can create sea caves and arches along coasts How might a raindrop change the surface of soil? Geosphere and Biosphere: Plant Roots Plants (part of the biosphere) interact with the geosphere Their roots can grow into cracks in rocks As roots grow, they can break rocks apart This helps create soil. Why is soil important?  Mountain Building: Folded Mountains Mountains form when parts of the geosphere collide Folded mountains form when rock layers push together and fold upward Examples: the Alps, the Himalayas If you squeezed a rug on a floor, what would happen? How is this like mountain building? Mountain Building: Fault-Block Mountains Fault-block mountains form when rock blocks move along cracks (faults) Some blocks move up while others move down Examples: the Sierra Nevada mountains Imagine a row of books. What would happen if you pushed up every other book? Volcanoes: Where Fire Meets Earth Volcanoes form when molten rock (magma) reaches the surface They're a dramatic example of the geosphere interacting with other systems Eruptions release gases into the atmosphere Lava can create new land in the ocean. How might this affect sea life?  Hot Spots and Island Building Some volcanoes form over "hot spots" in Earth's mantle As tectonic plates move over hot spots, they create chains of islands The Hawaiian islands formed this way If you moved a piece of paper over a candle flame, how might it be similar to hot spot volcanism? Landslides: When Gravity Wins Landslides occur when rock, soil, or debris moves down a slope They can be triggered by rain, earthquakes, or human activity Landslides show how the geosphere interacts with the hydrosphere and atmosphere What might happen to trees and animals in the path of a landslide? Minerals: Earth's Hidden Treasures Minerals are natural, solid substances that make up rocks They have specific chemical compositions and crystal structures Examples: quartz, gold, diamond How might minerals in the geosphere be important to living things?  The Rock Cycle: Earth's Recycling Program Rocks change form through the rock cycle Igneous rocks form from cooled magma Sedimentary rocks form from compressed sediments Metamorphic rocks form when existing rocks are changed by heat and pressure How is the rock cycle like recycling things at home?  Putting It All Together The geosphere constantly interacts with other Earth systems These interactions shape our planet's surface and affect life Understanding these connections helps us protect our environment What's one new thing you learned about how the geosphere interacts with other systems? Extreme Weather Events: A Focus on Thailand  Introduction to Extreme Weather Extreme weather events can be dangerous and damaging Thailand experiences various types of extreme weather We'll explore thunderstorms, tornados, tropical storms, and flooding How do these events impact Thailand? Thunderstorms in Thailand Thunderstorms are common in Thailand, especially during rainy season They bring heavy rain, strong winds, and lightning Can you name the months of Thailand's rainy season? Thunderstorms can cause flash floods and power outages  Tornadoes and Derechos Tornadoes are rare but can occur in Thailand A tornado is a rotating column of air that touches the ground Derechos are long-lived windstorms with a line of rapidly moving thunderstorms How do you think people in Thailand prepare for these events?  Tropical Storms Tropical storms are organized systems of thunderstorms They form over warm tropical oceans Can bring heavy rainfall and strong winds to Thailand What's the difference between a tropical storm and a regular thunderstorm? Typhoons and Hurricanes Typhoons are the same as hurricanes, just named differently in Asia The strongest tropical storms have winds of over 119 km/h Thailand is sometimes affected by typhoons from the Pacific Ocean How do you think a typhoon might affect daily life in Thailand?  Flooding in Thailand Flooding is a major concern in Thailand, especially in Bangkok Can be caused by heavy rains, tropical storms, or typhoons 2011 saw severe flooding affecting millions of people What challenges do you think flooding creates for Thai people?  Impact on Thai Agriculture Extreme weather greatly affects Thai farmers Too much rain can flood rice paddies Droughts can damage crops How might this impact Thailand's economy? Preparing for Extreme Weather Thai government has early warning systems People prepare emergency kits Some buildings are designed to withstand strong winds and floods What would you put in your emergency kit?  Climate Change and Thailand Climate change may increase extreme weather events in Thailand Rising sea levels threaten coastal areas Changing rainfall patterns affect agriculture How can Thai people adapt to these changes?  What Can We Learn? Extreme weather is a part of life in Thailand Understanding these events helps us prepare We can learn from how Thai people cope with extreme weather What's the most interesting thing you learned about extreme weather in Thailand?  Our Earth's Biosphere: Protecting Life on Our Planet What is Earth's Biosphere? The biosphere is all living things on Earth It includes plants, animals, and tiny organisms The biosphere interacts with other Earth systems: Atmosphere (air) Hydrosphere (water) Geosphere (land) How do you think these systems work together? Types of Pollution Water pollution: harmful substances in water Land pollution: waste and chemicals on land Air pollution: smoke and gases in the air Can you name one way each type of pollution happens?  Water Pollution: A Threat to Aquatic Life Caused by trash, sewage, and chemicals in water Harms fish, frogs, and other water creatures Some animals may not survive in polluted water How can we reduce water pollution in our daily lives? Land Pollution: Damaging Our Soil and Habitats Happens when we litter or dump waste on land Hurts soil quality and animals living on land Can lead to loss of habitats for many creatures What are some ways we can reduce land pollution? Air Pollution: The Invisible Threat Caused by burning trash, car exhaust, and factory smoke Makes air dirty and harmful to breathe Affects humans, animals, and plants Can you think of ways to reduce air pollution?  Overfishing: Emptying Our Oceans Catching too many fish too quickly Disrupts marine ecosystems Some fish species become endangered How might overfishing affect other animals in the ocean? Deforestation: Losing Our Green Lungs Cutting down forests faster than they can regrow Destroys habitats for many animals Contributes to climate change Why are forests important for Earth's biosphere? Endangered vs. Extinct Species Endangered: at risk of becoming extinct Extinct: no longer existing on Earth Human activities often cause species to become endangered Can you name an endangered animal? Why is it endangered?  Protecting Our Biosphere Reduce, reuse, recycle to minimize waste Conserve water and energy Plant trees and protect green spaces What's one thing you can do today to help our biosphere? Your Turn: Model the Biosphere Create a model showing how the biosphere interacts with: Atmosphere Hydrosphere Geosphere Include examples of plants, animals, and their environments How does pollution affect your model ecosystem? Earth's Atmosphere and Weather Systems  Introduction to Earth's Atmosphere The atmosphere is the layer of gases surrounding our planet It's made up of different layers: troposphere, stratosphere, mesosphere, and thermosphere The atmosphere interacts with other Earth systems like the hydrosphere and biosphere Can you name something in each layer of the atmosphere? What is Weather? Weather is the day-to-day state of the atmosphere It includes temperature, humidity, precipitation, cloudiness, and wind Weather is different from climate, which is long-term weather patterns What's your favorite type of weather? Why?  Understanding Air Masses An air mass is a large body of air with similar temperature and humidity Air masses form over large areas like oceans or continents They can be warm or cold, and moist or dry Can you guess where warm, moist air masses might form?  Warm Air Masses Warm air masses form over tropical or subtropical areas They bring warm temperatures and often high humidity Examples include maritime tropical (mT) and continental tropical (cT) air masses How do you think a warm air mass might affect your day?  Cold Air Masses Cold air masses form over polar or arctic regions They bring cold temperatures and often dry conditions Examples include maritime polar (mP) and continental polar (cP) air masses What changes might you notice when a cold air mass moves into your area?  Air Masses that Affect Thailand mT (Maritime Tropical) - Warm, moist air from tropical oceans; brings heavy rainfall and humidity. mE (Maritime Equatorial) - Extremely moist and warm air from equatorial seas; enhances monsoon rains. cT (Continental Tropical) - Hot, dry air from the interior landmasses; can cause drought conditions. cP (Continental Polar) - Cold, dry air from Siberia; responsible for cooler winter weather in northern Thailand. mP (Maritime Polar) - Cool, moist air from the North Pacific; minimal influence, bringing occasional cool  What are Fronts? A front is the boundary between two different air masses Fronts often bring changes in weather There are different types of fronts: warm fronts, cold fronts, and stationary fronts Have you ever heard a weather forecaster talk about fronts?  Warm Fronts A warm front occurs when a warm air mass moves into an area of cold air Warm fronts often bring light precipitation and gradual warming They're represented by a red line with semi-circles on weather maps What kind of clouds do you think form during a warm front?  Cold Fronts A cold front happens when a cold air mass pushes into an area of warm air Cold fronts often bring sudden temperature drops and stormy weather They're shown by a blue line with triangles on weather maps How might the wind change when a cold front passes through?  Stationary Fronts A stationary front forms when warm and cold air masses meet but neither moves These fronts can bring extended periods of cloudy, wet weather They're represented by alternating red semi-circles and blue triangles on maps Why do you think it's called a "stationary" front?  Modeling Earth's Systems Scientists use models to understand how Earth's systems interact Models can show how the atmosphere affects weather patterns They help us predict how changes in one system might affect others Can you think of a way the atmosphere might interact with the ocean?  The Amazon Rainforest: Earth's Lungs Under Threat  Our Amazing Planet Earth Earth is home to an incredible variety of life Organisms live in many different environments Deserts, rainforests, tundras, underground, and underwater Earth is the only known planet with life What's your favorite animal or plant on Earth? Humans and the Environment Human activities can change Earth's environments These changes affect plants and animals Some changes can be harmful to nature We need to be careful about how we impact the planet How do you think humans affect the environment around you?  What is Deforestation? Deforestation means clearing large areas of forests Forests are cut down for: Building cities and farms Collecting wood and other resources Causes big changes to the environment How might deforestation affect animals in the forest?  Effects of Deforestation Trees and plants don't survive Animals may die or have to move Less oxygen is produced More carbon dioxide in the air Contributes to global warming Can you think of other ways deforestation might affect the Earth?  The Amazon Rainforest World's largest rainforest Located in South America Covers 5.5 million square kilometers Called the "lungs of the Earth" Why do you think it's called the lungs of the Earth? Amazing Amazon Diversity Over 40,000 types of plants Thousands of different vertebrates More than 2 million kinds of insects Home to 1 in 10 known species on Earth What's the most interesting Amazon animal you've heard of?  Deforestation in the Amazon Happening at an alarming rate About 14,000 square kilometers lost each year Used for farming, roads, dams, and settlements Many plants and animals are at risk How do you feel about the Amazon being cut down?  Why Should We Care? The Amazon is important for the whole planet It helps clean our air Home to many unique plants and animals Some species might become extinct What would you miss if the Amazon disappeared?  What Can We Do?
