5th Grade Science Review (Unit 3 - Unit 4)

A scientist who studies earthquakes.

• Seismologist
• Paleontologist
• Orthopedist
• Pediatrician

What is a destructive force?

• A natural process that destroys land
• A natural process that creates land
• A natural process where areas that are normally dry is covered in water

A constructive force is defined as

• a natural occurrence that can build up or break down
• an earthquake or a volcano
• a natural force that builds up and creates new land
• a destructive force that has been controlled

Earthquakes and volcanoes are______________ forces.

• constrcutive and destructive
• constructive
• physical changes
• destructive

The Grand Canyon is a result of which of these destructive processes?

• earthquake
• erosion
• tornadoes
• volcanoes

A group of scientist went to visit the coast and returned a year later and noted the beach was smaller. What happened?

• The ocean water caused erosion.

• The ocean water caused deposition.

• Fault movement caused erosion.

• Fault movement caused deposition.

According to the table, what does the data show?

• Water is eroding sand to create a gully.

• Wind is depositing sand to form a dune.

• Rock is being deposited by ocean waves.

• Shells are washing ashore from the ocean.

Why would a scientist recommend dredging for an area of the coastline that is getting smaller?

• To rebuild beaches lost to water erosion.

• To act as a barrier to reduce wind erosion.

• To protect wildlife in the ocean.

• To act as a flood control measure.

Why would a scientist use a seismograph?

• To record the size of a wave.

• To measure the strength of a tsunami.

• To record the strength of an earthquake.

• To measure the duration of a volcanic eruption.

Why would a scientist use an instrument to predict the probability of a volcanic eruption?

• To estimate how much lava will flow.

• To protect nearby houses and buildings.

• To warn people who live nearby.

• To study weather changes.
