Which of the following best explains the difference between a mountain and a hill in Florida?

• A. Hills are formed near bodies of water while mountains are not, explaining why Florida has

  so many hills.

• B. Mountains are higher and steeper than hills, explaining why mountains are not found in

  Florida's low elevation.

• C. Mountains are found in places that are dry and cold, explaining why mountains are not

  found in Florida's climate.

• D. Hills are formed by rocks while mountains are made out of sand, explaining why Florida

  has so many mountains.

Which process causes the build up of sediment at the end of the river?

• A. Temperature changes cause the river to deposit sediment.

• B. The water current changes direction and breaks down the sediment.

• C. Deposition of the soil that was weathered and eroded from the river bank.

• D. Chemical weathering causes the river to break down and erode sediment.

While visiting a cave within a national park, Ava notices that some of the rock formations have

deep grooves and are less detailed than others. The park ranger explains that the rock

formations outside the cave entrance are more weathered than those deeper inside.

Which statement best explains why the rock formations outside the cave entrance are more

weathered?

• A. Physical weathering by the wind has blown sand against the formations, wearing them

  down.

• B. Chemical weathering by animals moving through the cave has broken pieces off of the

  formations.

• C. Slightly acidic rainwater has dissolved the rock formations over time through the process

  of chemical weathering.

• D. Tree roots have grown into cracks in the formations, causing them to break apart through

  the process of physical weathering.

Which of the following statements explains why scientists would recommend not cutting down

forests?
