Weathering Recap

The process of breaking up rocks on Earth's surface is known as what?

• sediment

• erosion

• weathering

• deposition

Water getting into cracks, freezing, and breaking the rocks or pavement apart is an examples of what?

• Mechanical Weathering

• Erosion

• Deposition

• Chemical Weathering

In which type of climate would weathering happen the fastest to a rock?

• wet and warm
• dry and cold
• wet and cold
• dry and warm

Which factors are the most important for determining the rate of weathering?

• Erosion and deposition
• Climate and type of rock
• Humidity and climate
• Humidity and temperature

What is carbonation?

• When carbonic acid breaks down calcium carbonate, creating calcium bicarbonate

• When calcium acid breaks down calcium bicarbonate, creating calcium bicarbonate

• When carbonic carbonate breaks down calcium carbonate, creating calcium acid

• When carbonic acid breaks down calcium bicarbonate, creating calcium carbonate

These gravestones have slowly broken down and turned a blackish color due to the action of:

• ice wedging
• abrasion
• acid rain
• mechanical weathering

Bobby observed that a metal trash can was covered with rust.  What type of weathering caused the rust on the trash can?

• Mechanical weathering 
• Wind weathering
• Chemical weathering
• Erosion weathering

When Joe saw the Rocky Mountains for the first time, he exclaimed, "These mountains are much younger than ours back East!" Which feature supports his conclusion that the Rockies were relatively young mountains?

• Their sedimentary layers are still exposed
• They have rounded tops
• They have sharp peaks
• Weathering has not yet hardened the rock

Which of the following is an example of erosion

• the sun shining on a rock

• Wind abrasion rounding the corners of a rock

• A river carrying soil to the ocean

• A lichen growing on a rock

Which of the following does NOT affect the rate at which a rock weathers?

• What the rock is made of

• The climate where the rock is found

• The amount of exposed surface area on the rock

• The length of time since the rock was formed
