What is the difference between the Flowing Water Model and flowing water on Earth?

Back

The Flowing Water Model is different because it only has sand at the surface, while Earth has various types of rocks and vegetation.

Front

What type of landform does lava create?

Back

Lava creates a straight channel that fans out as it flows.

Front

What is a geologic process?

Back

A geologic process is a natural process that shapes the Earth's surface, such as erosion, sedimentation, and volcanic activity.

Front

What is the purpose of models in geology?

Back

Models represent natural processes being investigated and help scientists test ideas about complex geological phenomena.

Front

What evidence can landforms provide about the past?

Back

Landforms can provide evidence about the past because they remain after the geologic processes that formed them have stopped.

Front

What is the geosphere?

Back

The geosphere is the solid part of the Earth, including rocks, soil, and landforms.

Front

What is the biosphere?

Back

The biosphere is the part of Earth where life exists, including land, water, and the atmosphere.
