Landforms

Dunes form in any place where there is a lot of sand and prevailing winds, such as in a desert. However, Florida does not have any deserts. Which statement best describes most of Florida’s dunes?

• dunes formed by sediment from mountains

• dunes formed by sediment carried by rivers

• coastal dunes behind rocky cliffs

• coastal dunes behind sandy beaches

Which is the main effect glaciers had on Florida?

• They made the climate cooler.

• They flattened the land by eroding it.

• They filled lakes and aquifers with meltwater.

• They affected ocean levels, causing waves to affect different areas of the coastline at different times.

• coastline

• mountain

• plateau

• plain

Strong waves can erode coastlines like the Gulf Coast of Florida. Which is most likely the result of erosion by strong waves?

• flat, sandy beaches

• cliffs and bluffs

• deltas

• sand dunes

What are two common ways that lakes are fed with water?

• rivers and streams

• rivers and sediment

• streams and sediment

• streams and deltas

Why are sinkholes common in Florida?

• Florida has a lot of oil underground. When the oil is removed, there is nothing left to hold up the soil.

• Florida's underlying rock is limestone. Limestone dissolves easily, forming caverns which can then collapse and form a sinkhole.

• Florida has a lot of swamps with animals that burrow into the sandy soil making holes and tunnels that collapse.

• Florida is a peninsula. Sinkholes are commonly formed on peninsulas because a peninsula is surrounded by water.

Sediment from mountains many miles away is continually being transported to Florida.

Which is the best explanation as to how this sediment moved so far away from where the mountains are now?

• The wind blew the sediment there.

• The sediment was transported and deposited by streams and rivers.

• This range of mountains used to be much farther south than it is now.

• Rocks form smaller, easily transported sediment on the southern side of mountains.

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

• A hill is made out of only rocks, while a mountain is made out of only sand, explaining why Florida has so many mountains.

• Mountains are found in places that are always dry and hot, which is why Florida has mountains but not hills.

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

• A mountain is usually higher and steeper than a hill, which is why mountains are not found in Florida's low elevation.

What is a mound of sand that was formed and moves by the action of wind?

• dune

• coasltine

• mountain

• beach
