Study Notes
Earth's Systems: Geosphere
- The geosphere is Earth's solid part, including rocks, minerals, and soil.
- It includes Earth's crust and mantle.
- Rocks, minerals, and soil make up the geosphere.
- The geosphere can be solid or molten (melted).
Earth's Systems: Interacting Systems
- The geosphere interacts with other Earth systems, such as the atmosphere, hydrosphere, and biosphere.
- Wind erosion shapes rocks over time, creating arches and pillars.
- Water erosion, from rivers and waves, creates canyons and sea caves.
- Plant roots grow into cracks in rocks, breaking them apart, and forming soil.
- Mountain building occurs when parts of the geosphere collide, forming folded or fault-block mountains.
Earth's Systems: Volcanoes
- Volcanoes form when molten rock (magma) reaches the Earth's surface.
- Volcanic eruptions release gases into the atmosphere.
- Lava cools and creates new landforms, often in the ocean.
- Some volcanoes form over "hot spots" in Earth's mantle, creating island chains like the Hawaiian Islands.
Earth's Systems: Landslides
- Landslides occur when rock, soil, or debris moves down a slope.
- Landslides are caused by rain, earthquakes, or human activity.
- Landslides illustrate the interactions between the geosphere, hydrosphere, and atmosphere.
Earth's Systems: Minerals
- Minerals are natural, solid substances that make up rocks.
- Minerals have specific chemical compositions and crystal structures.
- Examples include quartz, gold, and diamond.
Earth's Systems: The Rock Cycle
- 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.
Earth's Systems: Putting It All Together
- The geosphere constantly interacts with other Earth systems.
- These interactions shape Earth's surface and affect life.
- Understanding these connections helps protect the environment.
Extreme Weather Events: Thailand
- Extreme weather events like thunderstorms, tornadoes, tropical storms, and flooding occur in Thailand.
- Thunderstorms bring heavy rain, strong winds, and lightning.
- Tornadoes are rare but can occur.
- Derechos are long-lived windstorms.
- Tropical storms are organized systems of thunderstorms from warm tropical oceans and bring heavy rainfall and strong winds.
- Typhoons are the same as hurricanes but are named differently in Asia.
- Flooding is a major concern, especially in Bangkok.
- Extreme weather affects Thai farmers and crops.
Earth's Biosphere
- The biosphere includes all living things on Earth—plants, animals, and tiny organisms.
- The biosphere interacts with other Earth systems—atmosphere, hydrosphere, and geosphere.
Types of Pollution
- Pollution includes water, land, and air pollution.
- Water pollution comes from harmful substances.
- Land pollution comes from waste and chemicals.
- Air pollution comes from smoke, gases, and factory emissions.
Overfishing, Deforestation, Endangered Species
- Overfishing depletes fish populations, disrupting marine ecosystems.
- Deforestation removes forests faster than they can regrow, leading to habitat loss and contributing to climate change.
- Endangered species are at risk of extinction from human activities.
Protecting Earth's Systems
- Reduce, reuse, recycle.
- Conserve water & energy
- Plant trees
Earth's Atmosphere & Weather Systems
- The atmosphere is the layer of gases surrounding Earth.
- It has different layers: troposphere, stratosphere, mesosphere, and thermosphere.
- Weather is the day-to-day state of the atmosphere.
- Climate is long-term weather patterns.
Air Masses
- Air masses are large bodies of air with similar temperatures and humidity.
- Warm air masses form over tropical or subtropical areas.
- Cold air masses form over polar or arctic regions.
- Air masses that affect Thailand include Maritime Tropical, Equatorial, Continental Tropical, Continental Polar, and Maritime Polar air masses.
Fronts
- Fronts are boundaries between different air masses.
- Fronts can bring changes in weather.
- Types of fronts include warm, cold, and stationary fronts.
Modeling Earth's Systems
- Scientists use models to understand how Earth's systems interact, and affect each other.
- These models can show how the atmosphere affects weather patterns.
The Amazon Rainforest
- The Amazon rainforest is the largest rainforest in the world, located in South America.
- It is home to a vast biodiversity of plants, animals, and insects.
- The Amazon is a crucial part of the global climate system.
- Deforestation in the Amazon is a threat to the environment.
