Gravity and Earth Processes Quiz

Which statements below are evidence of gravity’s effect on Earth’s surface? (Select all that apply.)

• Plant roots push up and out of the soil.

• Cracks along the ground develop over long periods.

• Rocks, water, and mud fall from higher to lower points.

• Digging animals can’t burrow very deep into the ground.

Which processes shaped the sand dunes in this photo of a desert area? (Select all that apply.)

• Sand was deposited by wind.

• Glaciers carried sand to this new location.

• Gravity forces the piles up higher.

• Sand is being weathered by water.

What forces likely caused the changes shown in the photo of a rocky hillside? Use evidence to support your claim.

• Weathering – Wind and water break down rock.

• Erosion – Moving water carries away sediment.

• Gravity – Rocks fall from higher to lower areas.

• Volcanic activity – Lava reshapes the hillside.

Which of the factors below can cause structural changes on Earth to happen slowly? (Select all that apply.)

• Vegetation – Roots break down rock over time.

• Glaciers – Slowly move and carve landscapes.

• Clouds

• Floods

Plant roots can cause Earth’s surface to change. What factors influence how long it takes plant roots to weather rocks? (Select all that apply.)

• Type of rock – Softer rocks weather faster.

• Climate – More moisture and temperature changes speed up weathering.

• Plant type – Some plants have stronger, deeper roots.

• Soil conditions – More nutrients support stronger root growth.
