Constructive/Destructive Forces Review S5E1-a,b

Which describes a constructive process that creates new surface features?

• erosion, because it can carve canyons

• deposition, because is can create deltas

• impact of organisms, because humans build things

• weathering, because it makes new rock formations

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

Sand dunes can be viewed in the picture. What is the best way to simulate the formation of sand dunes?

• Use a hair dryer to blow sand into piles showing how wind can deposit sand in new locations.

• Use ice to move sand from one place to another the way that a glacier would on the earth's surface.

• Use water and sand to show how water can move sand from one place to another through the process of erosion.

• Use sand and a shaky table to show how earthquakes can move parts of the earths surface.

What type of process most likely created the mountain chain seen here?

• Volcanic eruptions created the mountains over millions of years.

• Tectonic plates pushed together forcing one plate under the other and then pushing the land upward.

• Earthquakes broke the earth into pieces and parts of it fell into cracks between faults.

• A river flowed through the land and created the valleys between the mountains making them appear taller.

The picture shows a volcano erupting.

A student claims that the volcano is showing a constructive force.

Which argument BEST supports the student’s claim?

• The top of the volcano exploded, causing rocks to break apart.

• The lava damages the surrounding land so that plants can no longer grow.

• The flowing lava cools and creates a layer of volcanic rock.

• The lava pushes the soil down to the base of the volcano causing plants to grow only at the volcano’s base.

A student developed a model to show the progression of a sea arch and the ocean waves using playdoh. Dates labeled below the image show a timelapse.

Four of the student’s classmates analyzed the student model on how the model shows constructive and destructive forces. Which of the following students made a correct conclusion based upon the model?

• Student A: A sea arch is formed by a destructive force. Evidence from the model is that waves carved out the land in a long period of time.

• Student B: A sea arch is formed by a constructive force. Evidence from the model is that waves build up land in another area in a long period of time.

• Student C: A sea arch is formed by a destructive force. Evidence from the model is that an earthquake caused the arch to fall down in a short period of time.

• Student D: A sea arch is formed by a constructive force. Evidence from the model exhibits deposition when the waves build up the land in a short period of time.

A student argues that a destructive force can change the surface of Earth. Which of the following could be used to support this claim?

• 
  A new island forms in the middle of an ocean.

• A plain becomes a deep canyon with steep walls.

• A sand dune shifts from one location to another.

• A mountain grows taller over a thousand years.

Over many years, the depth of a lake gets more shallow.

What could cause this change?

• The climate in the area gets warmer

• Sediments are deposited in the lake.

• The Sun evaporates the water.

• 
  A hurricane brings heavy rains.

Students were tasked with making a model of how natural forces can change the surface features of Earth. They make a pile of sand in front of an electric fan and turn it on.

This model best represents which of the following changes to the surface of Earth?

• Volcanic eruption
• A delta being formed

• Earthquake-induced landslide
• Erosion caused by wind
