Study Notes

Fossils

Fossils are molds of plants and animals that lived thousands of years ago, and are divided into two types: trace fossils and body fossils.
Trace fossils are evidence of animal activity that is preserved, while body fossils are remains of a plant or animal that were trapped under dirt and preserved over a long period of time.
Fossils are usually found in sedimentary rock, and have been found on all continents, with a higher concentration in North and South America, and Asia.
Some fossils are found in amber, which is a resin that preserves animals, and coprolite, which is fossilized animal poop.

The Water Cycle

The water cycle is a set of repeated events that involve evaporation, condensation, precipitation, and collection.
Evaporation occurs when water is warmed up and turns into a gas.
Condensation occurs when water gas gets cold and turns back into a liquid.
Precipitation occurs when water falls back to the earth.
Collection occurs when water is stored in lakes, rivers, oceans, soil, and rocks.

Clouds

There are four main types of clouds: cumulus, stratus, alto, and cirrus.
Cumulus clouds are puffy and white, like cotton balls.
Stratus clouds are flat and white, like sheets.
Alto clouds are made of water droplets and sometimes ice droplets.
Cirrus clouds are white and wispy, and come with rain-free weather.

The Atmosphere

The atmosphere is the circle of gas that surrounds planet Earth, and is divided into five layers: Troposphere, Mesosphere, Stratosphere, Thermosphere, and Exosphere.

Solar Radiation

Solar radiation is sunlight and energy that comes from the sun and travels to Earth in the form of light waves.
Light waves come in different forms, vibrate, and have different lengths and energy levels.
Solar radiation is necessary for living things to survive on Earth, and provides visible light, infrared light, and ultraviolet (UV) light.

Wind

Wind is the movement of air caused by differences in air pressure.
The wind blows because the sun heats land faster than it heats water, which causes changes in air pressure.
Meteorologists use instruments like an anemometer to measure wind speed.
Wind energy can be captured using wind turbines, which spin like giant pinwheels.

Prevailing Winds

Prevailing winds are dominant winds in a certain area.
Wind direction is where the wind is coming from, and wind speed is the measurement of how fast the air is moving.
Tools for measuring wind speed include an anemometer and the Beaufort scale, which rates wind from 0-12.

Air Pressure

Air has weight, and because of that, exerts pressure.
Meteorologists measure pressure to predict the weather.
In a high pressure area, air molecules are held down, resulting in clear, sunny days.
In a low pressure area, air and water molecules are able to float high into the sky, resulting in cloudy, rainy days.

Air Masses

Air masses that stay in a particular area begin to take on the characteristics of the temperature and humidity in that area.
There are six kinds of air masses, each named after the locations in which they form: maritime tropical, continental arctic, maritime arctic, maritime polar, continental polar, and continental tropical.
Air masses can move from one area of the world to another because of jet streams, which move from west to east.
When air masses move, they affect the weather because they take with them the characteristics of their birthplaces.

Cloud Formation

Clouds can be created for a number of reasons, including convectional lifting, cold fronts, warm fronts, stationary fronts, and occluded fronts.
Convectional lifting occurs when warm, humid air rises and begins to cool, causing the water vapor to condense into clouds.
Cold fronts occur when a cold air mass takes over a warm air mass, causing it to go up into the atmosphere.
Warm fronts occur when a warm air mass takes over a cold air mass, leaving warm air.
Stationary fronts occur when neither the warm air mass nor cold air mass moves.
Occluded fronts occur when a cold front is created in a low pressure area.

Tornadoes

A tornado is a spinning column of air that stretches from a thunderstorm to the ground.
Tornado winds are very strong, which makes them dangerous.
Tornadoes form in a thunderstorm when an area of warm air meets an area of cold air, and the winds are blowing in just the right way.
Tornadoes have struck every single U.S. state, including Hawaii, but the area of greatest concern is Tornado Alley, which includes parts of Texas, Oklahoma, Kansas, and Nebraska.

Hurricanes

Hurricanes are powerful storms that form over oceans and get their energy from the warm ocean waters.
Hurricane winds blow at 74 to 200 miles per hour and spin due to the Coriolis effect, which is a force created by the spinning of the Earth.
The calm area in the center of a hurricane is called the eye.

Thunderstorms

A thunderstorm is a rainstorm with thunder and lightning.
Thunderstorms need moisture, unstable air, and lift to form.
Thunderstorms have three stages: developing, mature, and dissipating.
They can happen almost anywhere in the world and in any season.
They can occur at any time of day, although most often in the afternoon and evening.

Lightning

Lightning is a flash of light produced by electricity when negatively-charged electrons and positively-charged protons collide.
There are different kinds of lightning, including cloud-to-ground, cloud-to-cloud, intra-cloud, and cloud-to-air.
Lightning is dangerous, and the best way to stay safe is to get inside a big building and stay away from windows.

Ecosystems

Ecosystems are specific areas that can be either in water (aquatic) or on land (terrestrial).
An ecosystem is made up of living organisms and non-living things that depend on each other for survival.
We also learned about food chains, which include producers, primary consumers, secondary consumers, decomposers, and omnivores.

Energy Transfer

In order to survive, living things need energy, and energy passes from a producer (which are plants that make their own energy from the sunlight) into herbivores (plant-eating animals), carnivores (meat-eating animals), and omnivores (animals that eat both plants and meat).
We use food chains to represent a single flow of energy and we use food webs to represent the feeding relationship between many living things within a community.

The Energy Pyramid

The energy pyramid shows us how energy transfers from one organism to the next on the food chain.

Weather

Weather is the state of the atmosphere at any given time.
Weather is affected by the Sun's rays and their interaction with the gases in the Earth's atmosphere.
Weather has many aspects, including wind, pressure, cloud cover, temperature, and precipitation.

Climate

Climate is the pattern of weather in an area over a long period of time.
It's impacted by different factors, including temperature, humidity, distance from bodies of water, wind, the amount and types of precipitation, topography, latitude, and elevation.
There are five main types of climate: tropical, dry, mild, continental, and polar.

Forecasting

A forecast is a prediction, or good guess, about the future.
Weather forecasting is when scientists called meteorologists use many different tools to predict what the weather in the near future will be.
Meteorologists pay attention to the temperature, air pressure, clouds, and other factors to make their predictions.

Meteorologists

Scientists who study the atmosphere and predict the weather are called meteorologists.
They use weather maps to show what the weather forecast will be, and these weather maps are important because they show us how to plan our day and week.
There are several types of weather maps, such as satellite, precipitation, temperature, front maps, wind speed, and Doppler radar.
