Unit 2 Remediation

The process of sediment being dropped off in a new location is called ____________?

• Deposition

• Erosion

• Weathering

• Displacement

The diagram shows a geographic feature.

Based on the diagram, structure X is

• a delta that is changing due to sediment deposits from ocean currents.

• an island that is changing due to the movement of plate boundaries.

• a delta that is changing due to sediment deposits from a river.

• an island that is changing due to increasing volcanic lava flow.

Sand Key is a barrier island located along the coast of Florida. Which process most likely caused Sand Key to form?

• sudden erosion of a sandbar

• deposition of sand over time

• wearing down of seashells

• effects of a hurricane

Which process describes the wearing away of rock?

• drainage

• erosion

• infiltration

• weathering

A student observed a tree growing out of rock as shown.

Which of the following most likely describes what the student observed?

• The rock fell apart under the force of gravity, opening a basin in which the tree could grow.

• The wind carried the seed for the tree into the crack, which sheltered it and allowed it to grow tall.

• The roots of the tree grew into a small crack in the rocks, causing the crack to widen and rock to break.

• The weathered surface of the rock had a large force of friction, which pulled the roots down into the crack.

The picture shows the Grand Canyon.

Which statement best explains how this canyon formed over millions of years?

• Wind deposited sand and silt that formed the steep mountains.

• Rivers carried sand along the banks and formed steep plateaus.

• Rain fell in the area and caused the sides of the hills to fall down.

• Water and flowing rivers wore away the sides of raised landforms.

The drawing shows the growth of a plant in a crack in a rock.

What will happen to the rock if the plant continues to grow as it is in the drawing?

• The plant's roots will erode the rock, pulling minerals from the rock and transporting them to the atmosphere.

• The plant's roots will weather the rock, widening the crack and eventually breaking the rock.

• The rock will absorb new minerals from the plant, transforming into a different type of rock.

• The rock will absorb oxygen from the plant, expanding until it breaks into rock particles.

Water fills a crack in a rock. The temperature drops below freezing. What is likely to happen?

• The water in the crack will evaporate.

• The water will freeze and the crack in the rock will expand.

• The water will freeze and the crack will stay the same.

• The water in the crack will protect the rock from further cracks.

Adrian is making a model to show how burning coal and other fossil fuels pollutes the air and can cause acid rain. In the model, she wants to show what would most likely happen to rocks and the surface of the Earth if humans continue to pollute the air by burning fossil fuels. Which of the following should she show in her model?

• Acid in rain physically weathering rocks, speeding up the process of erosion on the surface of Earth.

• Acid in rain chemically weathering rocks, speeding up the process of erosion on the surface of Earth.

• Acid in rain physically eroding rocks, speeding up the process of weathering on the surface of Earth.

• Acid in rain chemically eroding rocks, speeding up the process of weathering on the surface of Earth.

The picture shows a rock formation.

What most likely caused this rock formation?

• wind erosion over many years

• erosion by waves over many years

• the rock was chipped away by animals

• high temperatures that melted the rock
