What is differential weathering?
It is when softer, more weather resistant rocks wear away at a faster rate than harder, less weather resistant rocks.
100
True or false, the more surface area that is exposed to weathering, the slower it will take for the rock to be worn down.
flase

What is the climate of Florida's summers and winters?
Winters are wet and mild while summers are hot and dry.
100
What form of weathering can break the hardest rocks?
Ice- wedging
100
True or False: An increased surface area makes weathering happen at a faster rate
true
200
True or false: Hard rocks weather more slowly than soft rocks
True
200
If a large rock has a large surface area and volume, would it wear away quickly or slowly?
slowly
200
What is Florida's climate like?
Subtropical, warm, or humid
200
temperature does the rate of chemical weathering happen faster?
In subtropical climates
200
What affects the rate of weathering for rocks near sea elevation?
The action of waves
300
What is an example of differential weathering mentioned in the textbook?
Devils Tower, Wyoming
300
Why would weathering be quicker to a rock that is broken up in peices?
The fragments would be smaller
300
Do you think the chemical weathering would happen faster or slower in FL?
faster

What does ice wedging do to a rock?
It can cause cracks in the rock and can sometimes break it.
300
What part of a mountain or hill increases the rate of weathering?
The steep sides

What is climate?
Climate is the average weather condidtion in an area over a long period of time.
500
When does chemical reactions happen at a faster rate?
When the climate is warm and water is present.

What two things works together to weather rocks?
Elevation and gravity
