this contains all the living organisms and the environments that they live in.
this is the part of the earth that includes rock - the hard outer shell of the planet, including crust and mantle, and the molten rock underneath the earth's surface
this includes all of the water on the planet - liquid, frozen, or in the atmosphere. Most of the earth is covered with water of some variety; mostly salt water is in the oceans. Of the 3% freshwater into glaciers or underground.
this is earth's protective blanket of air and is what helps keep temperatures reasonable. If temperature get too hot, water vaporizes. If the temperatures get too cold, the water would be frozen. Earth's atmosphere allows us to have liquid water and provides the necessary gases for living organisms.

changes that occur in a rock when the rock comes in contact with substances such as acids
the process of removal and movement of surface materials from one place to another.

soil that is made of the same type of rock found in the bedrock beneath it.
soil that was formed in one location and then moved by the process of erosion to another location
naturally occurring soil substance with specific chemical composition and a crystalline structure
bits of weathered rock that can be transported by erosion.
a geographic area with similar climate, vegetation, and animal life.

a biome that is characterized by its lack of moisture and extreme temperature changes between daytime and nighttime.
organisms that have fur, give birth to live young, and feed milk to their young.
molecules that are attracted to water

a tree that seasonally drops its leaves.
a grassland biome that is characterized by its seasonal rain and lack of large trees.

a grassland biome found in the US that is particularly well suited for growing crops.
a biome that is a cold forest characterized by conifers and cold winters.
this is a type of biome that receives little water, usually in the form of snow; very large plants and animals are found in this biome, but many types of smaller organisms thrive during the warmer summer months.
