Soil
The land that gets covered by water during a flood
Floodplain
A small mountain; lower and less steep than a mountain
Hill
The __________________is the continuous movement of water between the Earth’s atmosphere and its surface.
water cycle
A fan shaped deposit at the mouth of a river
Delta
Soil is made up of?
Rocks, humus, organisms
.A curve or loop in the river
Meander
What organisms are found in Soil?
Worms, insects, bacteria
When water falls from the sky in the form of rain, hail, snow, or sleet it is ______________________________.
precipitation
A low area between hills and mountains, often where a river flows
Valley
When big rocks break into smaller rocks that is known as
Weathering
What 3 natural events cause Erosion
Water, Wind, Ice
A high, uplifted area with steep slopes
Mountain
________________________ is when water vapor cools and becomes droplets of water.
Condensation
A deep valley with steep sides eroded by the river
Canyon
The process by which eroded materials settle out in another place is known as
Deposition
A river carrying water away from a hill is an example of
Erosion
What are the 2 types of weathering and what is the difference between the two
Physical-the breaking down of rocks WITHOUT changing what its made of
Chemical-the breaking down of rocks and it DOES CHANGE the mineral makeup of the rock
When water becomes water vapor when heated that is called ________________________.
Evaporation

Sand dunes forming at the desert is an example of
Deposition
What are the 3 categories of rocks and how are they formed?
Igenous-magma and cooled lava
Sedimentary-bits of pieces of rocks and minerals
Metamorphic- Made from other rocks that have gone through heat and pressure

What evidence does the composition of soil provide about where it came from?
Soil has rocks such as pebbles, gravel, sand, clay, and silt in it. In our investigation we found out that when we add water to soil and let it settle it forms layers. Based off of how much of each type of rock or material is in it, that gives us clues about where it came from. For example if it had mostly sand it came from the desert or beach.If it had mostly humus it came from the forest.If it had mostly gravel it came from the mountains.
