What is soil made of
Soil is a combo of rocks, water, air and humus
What is a body fossil
A body fossil is a organism that is wrapped in a ember
What type of rock is coal
Coal is sedimentary
How do mountains help the environment
They feed rivers and help the climate
What is another thing similar to erosion and weathering
Sandblasting
How many layers of soil is there
3 layers
What is a fossil
A fossil is a remnant of a organism
What are the 3 types of rocks
Igneous, Metamorphic and Sedimentary
What percent of the earth is covered with mountains

How do erosions happen
Erosion happens when water, wind, waves or glaciers pick up dirt and rocks and move them around
What layer of the soil has the most humus
Top soil
What is the rarest fossil
Body fossils
What rock needs heat to be a liquid and if it doesn't get heat it's a rock
Metamorphic rocks
How do glaciers form
The snow gets so high that the bottom layer starts to melt and turns into something kind of like puddy and it moves.
What do erosions create
Sandbars, Flood planes and River deltas
What makes it easier for plants to live in the soil
Humus makes it easier for plants to live in the soil
The more humus the more complex the plants can be
What is the easiest fossil to find
Trace fossils are the easiest to find
Igneous rocks
How are mountains formed
They form when plates shift, move apart or push together
