a different
The piling up of sediment that has been picked up and moved to a new place is called __________.
Deposition
This sphere describes the surface and landforms of a planet
Geosphere
These can provide evidence about the past because they remain after the geological processes that formed them stop happening.
Landforms
_____________________ is important to weathering because it causes water and rock pieces to move downhill.
Gravity
No, mountains will weather and erode over time.
Earth has 4 spheres that interact. When these spheres interact they form a ____________________________.

Erosion
This sphere describes the living things on a planet
biosphere
Scientists often use this to help test their ideas and gather evidence about things that are difficult to observe.
Model
This is the process of depositing sediment after it has been moved by water, wind, ice, or gravity.
Deposition
A tall rock in a desert being gradually being worn away by sand and wind rubbing against it would be an example of ___________________________.
Mechanical Weathering
This occurs when a large mass of soil or rock slides down a steep slope.
Landslide
This sphere describes the gases of a planet
atmosphere
This is the flat land located along a river.
Flood Plain
When rocks and minerals break down due to chemical reactions this has occurred
Chemical Weathering
