Landforms
Find the valley
A low area between hills and mountains, often where a river flows
First step of fossil formation
a living thing dies and gets buried in soil
Does slope affect erosion?
Yes, the larger the slope the more erosion occurs.
Fossil
Preserved remains of any living thing
Find the river
What types of fossils would you expect to find near the ocean?
Fish, starfish, lobster, crabs, sharks, etc.

What likely caused a valley to form?
a river slowly carved out the land
Deposition
The process by which eroded materials settle out in another place
Find the meander
A curve or loop in a river
What can fossils teach us?
What animals and plants lived long ago
What likely formed sand dunes?
wind blew the loose sand into dunes
Slope
The angle of the land over which water flows
Find the delta
A fan-shaped deposit at the mouth of a river
Are fossils only dinosaurs?
No, they can be any living thing.
Why is soil different in different places?
The materials that make up the soil are different in other location, and earth materials can get moved from place to place.
