While visiting an ancient cemetery, Kim notices that a statue of a cherub has most of its facial features worn away. Which statement best explains why the cherub's face has worn away over time?

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

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

• Slightly acidic rainwater has dissolved the rock formations over time through the process of chemical weathering.

• Tree roots have grown into cracks in the formations, causing them to break through the process of physical weathering.

• sand dunes and lakes

• sinkholes and mountains

Why don't we have mountains in Florida, but we do have hills?

• Hills form near bodies of water while mountains do not, which explains why Florida has so many hills.

• Mountains are taller and steeper than hills, which explains why mountains are not found in the low elevation of Florida.

• Mountains are found in places that are dry and cold, which explains why mountains are not found in Florida's climate.

• Hills are formed by rocks while mountains are made of sand, which explains why Florida has so many mountains.

What landform is created when groundwater erodes the rock causing the surface land to collapse?

• lakes

• aquifer

• caverns

• sinkhole

• deposition

• physical weathering

• chemical weathering

How do sand dunes in Florida, Texas, and Mexico protect coastal areas from flooding and storm surges?

• Sand dunes prevent erosion from the large waves that form during storm surges.

• Sand dunes provide places for sea turtles to lay their eggs.

• Sand dunes provide shade on a sunny day so you don't get sunburned.

• Sand dunes trap water on the beach to provide water for land animals.

Why is seagrass planted on sand dunes along the coasts?

• It decreases soil erosion.

• It increases weathering of the terrain.

• It provides more oxygen to the environment.

• It offers safety to those living on the sand dunes at the beach.

Which option explains how the mountain has changed over the years?

• The rivers eroded the side of the mountain

• Deposition has placed rocks in different places making the rocks look different

• The mountain has changed because erosion is building the mountain

• Gravity has contributed to the erosion

What process causes the accumulation of sediments at the end of the river?

• Temperature changes cause the river to deposit sediments.

• The water current changes direction and breaks down the sediments.

• Deposition of soil that was worn away and eroded from the riverbank.

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