Climate
The average weather conditions and characteristics in an area over a long period of time.
Atmosphere
The gas that surrounds the Earth. It is made up of five layers, starting closest to the Earth, they are: the troposphere, mesosphere, stratosphere, thermosphere, and exosphere.
Biotic
Living organisms
Abiotic
Non-living things
Ecology
The study of the interrelationships between organisms and the habitat in which they live.
Autotrophs
Organisms that can create their own food. Plants are the primary example of organisms in this group.
Heterotrophs
Organisms that get their energy through consuming outside sources, such as other organisms. Humans and animals are examples of this group.
Terrestrial Ecosystem
These are ecosystems found on land. Examples include rainforests, deserts, and forests.
Aquatic Ecosystems
These are ecosystems found in water. They can be freshwater, like rivers, streams and lakes, or marine, like the ocean.
Name the type of diagram seen here.
This is a food web. Food webs show the way energy moves between organisms in an ecosystem.
Name the three major trophic levels in the food chain.
Producers, consumers, and decomposers.
Identify the trophic level that grass, trees and flowers belong in.
These are examples of producers. They provide energy to other organisms.
Identify the trophic level that animals such as dogs, lions, and sharks belong in.
These are examples of consumers. They get their energy from eating producers.
Identify the trophic level that fungi and bacteria belong in.
These are examples of decomposers. They get energy from organisms that have died.
Tectonic Plates
The large sections that the top layer of the Earth's crust are divided into. They are responsible for creating volcanoes, mountains, valleys, and earthquakes.
Name the object seen here.
This is a man-made satellite. A satellite is an object that orbits (or circles around) another object.
Name the speed of light.
Light moves at a rate of 86,000 miles per second.
Light Year
This term is used to describe the distance that light could travel within a year. A single light year is nearly six trillion miles.
Electromagnetic Spectrum
This is a chart that shows electromagnetic waves and details how light waves travel. The small section of color pictured, is all that is visible to the human eye.
Name the seven types of electromagnetic waves.
Radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays and gamma rays.
