Landform Unit 1

Which of the following BEST compares the power of wind and earthquakes to change Earth's surface features?

• Wind power is only destructive because high wind speeds during storms are very damaging. Earthquake power is only constructive because it causes new land formations when two tectonic plates collide.

• Wind power in only constructive because it builds up sand dunes and moves them over time. Earthquake power is only destructive because it causes rifts and landslides.

• Wind power is both constructive and destructive because it build up dune shape or cause erosion over time. Earthquakes power is both constructive and destructive because it very quickly builds up new land formations or causes rifts and landslides.

• Wind power is only constructive because it moves large particles faster than small particles to build up dunes. Earthquake power is only destructive and is common on fault lines and is very damaging.

Which TWO statements describe a benefit of seismological studies?

• They help scientists predict and prevent major floods.

• They help scientists design materials that resist erosion.

• They help scientists decide where to install lightning rods.

• They help scientists warn citizens of approaching earthquakes.

• They help scientist understand the movement of tectonic plates.

Which of these factors would help reduce soil erosion?

• the loosening of soil

• a period of heavy rainfall

• the planting of more vegetation

• an increase in the slope of the land

The geological process by which material is added to a landform is called

• sediment

• erosion

• weathering

• deposition

A student claims that some landforms can be created through constructive processes. Which example should she choose as an argument to BEST support her claim?

• She should choose a cliff that can be created by ocean waves breaking down rock.

• She should choose a canyon that can be created by flowing water carving through rock.

• She should choose an island that can by created by the cooling lava of a volcanic eruption

• She should choose a valley that can be created by a retreating glacier carving the landscape.

Which statement BEST describes how a delta is formed?

• a delta is formed by the destructive process of sedimentation.

• a delta is formed by the destructive process of weathering

• a delta is formed by the constructive process of deposition

• a delta is formed by the constructive process of erosion

Why are levees built?

• to protect people from rising water during a large storm

• to keep animals from drinking the water

• to force water underground

• to collect water for drinking

The San Andreas Fault is in California, why would scientists NOT want to study this fault

• The history of the fault helps people appreciate technologyy.

• Buildings near the fault can be made of more shake proof materials

• knowing the location of the fault helps people avoid building homes and businesses near it

• seismographs can be placed all around the fault to watch fault activity and send out earthquake warnings

Why do models of weather patterns are different from the actual model?

• The incorrect computer program was used to predict that path of the hurricane.

• Models that represent nature cannot predict every change that may occur.

• Scientist did not share information with each other, so this model was based on a singular piece of information.

• Scientists could not agree on a predicted path, so the model showed an average of what the scientists predicted.

How do stilts on a home NOT protect the people who live in it?

• by raising the living space out of reach of high waters caused by heave rain and flooding

• by making the living space much cooler during hot weather because of circulating breezes

• by reducing wind damage to the house because wind is directed underneath the house.

• by reducing the effects of an earthquake because of the distance from the shaking ground
