What process transports rocks, soils and sediments to a different location?

Erosion

100

How are mountains formed?

Constructively as moving tectonic plates force land up

100

How are cliffs created?

Destructively through weathering as water wore down large rocks

100

What type of river causes the most erosion?

Long river with fast moving water

100

How can human interaction decrease the destructive force of hurricanes on coastal areas?

Create dams and levees to control water flow

200

Why are landslides on mountains destructive?

They cause earth’s surface to be broken down into smaller pieces

200

How are islands formed?

Lava from an ocean volcano cooled and hardened

200

How are canyons formed?

Destructively as steep walls are weathered away and eroded by water

200

What is beach restoration?

Replacing sand on the beach

200

What do seismographs measure?

How powerful an earthquake is

300

In an earthquake, what happens to Earth’s crust?

It chips and cracks as it rubs against itself.

300

How are deltas formed?

Constructive process of deposition. Moving water deposits sediment

300

What are sand dunes made of and how are they formed?

Made of sand from large areas of surrounding desert. Formed when wind and rain move sand through deposition

300

What earth process matches the following question scientists could ask for technology development: How can glass be design to withstand high-speed impacts?

hurricane

300

What does the Richter Scale determine?

magnitude

400

What is an underwater earthquake called?

Tsunami

400

A student creates a model to show the constructive process of a delta being formed. The student wants to know if the volume of the water flow affects the size of the delta. How can the student change the model to investigate this?

Add more water to the channel

400

How are river banks formed?

Constructively through deposition

400

What earth process matches the following question scientists could ask for technology development: How can water be contained to avoid property damage?

flood

400

What is infrared imaging and how may it give scientists information about volcanoes?

Technology that takes pictures of thermal energy (heat)

500

Where do the tectonic plates meet and show movement in an earthquake?

Fault

500

How are volcanoes also a constructive force?

When ocean volcanoes lava hardens and turns into rock, it creates islands

500

What could cause beaches to shrink?

Erosion by ocean waves

500

How can you prevent the effects of flooding?

retention pond

500

GIS maps can be used to limit the impact of flooding. In which two ways can the data from GIS maps be used?

to avoid building homes and businesses in areas that flood

to give people time to leave those areas
