What is one example of how weathering occurs?
Weathering occurs when.... - water freezes causing rocks to crack - rocks fall from higher places - tree roots break the rocks

What are sediments?
Sediments are rocks, sand, and soil.

How is weathering related to erosion?
Weathering breaks down the rocks that are then carried away by erosion.
300
Which erosion prevention strategy is build against the shoreline?
Seawalls

What does destructive process mean?
A destructive process breaks down landforms.
400
What are two activities by humans that cause erosion?
Farming and construction can accelerate (make faster) erosion.

What forms at the mouth (end) of a river due to deposition?
A delta forms at the mouth of a river.

Do all earth materials erode in the same way? How do you know?
No, earth materials erode differently. I know this because in our lab we used three different earth materials and material eroded in a different way.

What are the benefits of using jetties, seawalls, and breakwaters?
Jetties, seawalls, and breakwaters prevent erosion.

What is beach nourishment?
Beach nourishment is the moving of sand from place to another to rebuild an eroded beach.

What is one benefit of beach nourishment?
The benefits of beach nourishment are that it helps the tourism industry ($$$) and can prevent future damage to houses, roads, and businesses.
