Erosion, weathering, landforms

What are the two ways that rocks are broken down into smaller pieces?

• abrasion and erosion

• chemical weathering and dissolving

• physical weathering and precipitation

• chemical weathering and physical weathering

Weathering and erosion are two processes that shape Earth’s surface. Which of the following sets of factors causes both weathering and erosion?

• moving water, plant roots, wind

• acid rain, plants, ice wedging

• glaciers, ocean waves, wind

• acid rain, tree roots, waves

The earth is built up and torn down in many ways. Physical and chemical weathering are processes which are very important in making soil. Which statement accurately describes an example of chemical weathering?

• Tree roots break apart a rock.

• Sinkholes are formed in central Florida as seeping water dissolves underground limestone rocks.

• In Alaska, rocks are broken due to continuous freezing and thawing of water sitting in cracks.

• Blowing sand has created beautiful and strange rock formations in the Western United States.

The roof of a cave eroded and became thinner over time. The roof then collapsed and created a landform. What landform was created.

• canyon

• cavern

• delta

• sink hole

Which statement is correct?

• Dunes provide protection from erosion caused by water.

• Deltas create a natural barrier to prevent erosion by wind.

• Rivers limit flooding by preventing ocean water from moving inland.

• Sinkholes decrease the chance for flooding by providing a place for excess water to go.

Which explanation best describes how melting glaciers will effect Florida?

• Fresh water flooding caused plants to die.

• The shape of Florida’s coastline changed.

• Steep cliffs formed above Florida’s beaches.

• More sand was deposited on the ocean floor.

How do the rivers in Florida differ from those in other areas?

• Florida’s rivers carry more sediment than those that flow faster.

• Florida’s rivers are shallower than those in mountainous regions.

• Florida’s rivers move much faster than those in other parts of the country.

• Florida’s rivers are much deeper than those located in states farther north.

Which of the following BEST describes the many rivers that flow through the state of Florida?

• Florida’s rivers are very deep as a result of the force of the water rushing down mountains.

• Florida’s rivers are very slow due to the flatness of the terrain.

• Florida’s rivers are very swift and cause much erosion.

• Florida’s rivers always begin at the coastline.

What happens at a divergent tectonic plate boundary?

• Two tectonic plates move horizontally past one another along Earth’s surface, forming long fault lines.

• Two tectonic plates pull away from one another, forming a rift or ridge.

• Two tectonic plates pull away from one another, decreasing rock formation.

• Two tectonic plates collide with one another, causing subduction and/or mountain building.

Which of the following statements best explains the role heat flow has in changing Earth’s surface?

• Tectonic plates move when the lithosphere cools.

• Convection of the core causes the crust to move and volcanoes to erupt.

• Ocean basins form when convection of the mantle moves apart tectonic plates.

• Earthquakes occur when heat radiates out from the lithosphere and moves the crust.
