8th chapter 8

a process that wears away surface materials and moves them from one place to another

occurs when agents of erosion drop sediments they are carrying as they lose energy

a mound of sediments drifted by the wind

which type of glacier can form in warmer climate?

Deflation and abrasion most commonly occur in desert and beach areas. t/f?

Wind erosion can move large sediment. t/f?

material deposited by the meltwater from a glacier most often towards the end of the glacier

Till deposits cannot cover huge areas of land. t/f?

Rock slides occur very slowly. t/f?

wind deposits of fine grain sediment that settles on hilltops and valleys

this type of mass movement occurs when steep layers of rock slip downslope suddenly

One of the best ways to prevent erosion is to plant vegetation?

when a mass of materials slips down along a curved surface

a thick mixture of sediments and water flowing down a slope

a large mass of ice and snow moving on land under its own weight

one way that wind erodes by blowing loose sediment removing small particles

The greater an object's mass is, the greater the gravitational force will be. t/f?

A slump occurs when base material cannot support the rock and sediment above it. t/f?

which of these is caused by wind blowing sandy parts of deserts or other sandy areas?

When wind hits trees, its energy of motion increases. t/f?

a winding ridge of sand and gravel that forms when a glacier melts

this mass movement occurs when sediments slowly shift positions of trees or human structures downhill

occurs when wind blows soil particles long distances

What happens when glaciers pass over land?

Which of these occurs most likely when vegetation is removed by fire or after heavy rainfall?

Period of widespread glaciation was called the

a mixture of different sizes of sediment such as boulders, sand, clay and silt

what are the two types of glaciers?

Creep is common is areas of freezing and thawing. t/f?

what is the force of attraction that pulls all objects towards earth's center?

What percentage of earth do continental glaciers cover?

a process that occurs when a moving glacier picks up loosen rock particles

Shallow marks left on bedrock from glaciers are called what?

this type of mass movement occurs when blocks of rock break loose from a slope and tumble through the air

When glaciers melt, water flows into cracks of rock and causes erosion. t/f?

any type of erosion that happens as gravity moves materials downslope

When windblown sediment strikes rock and the surface gets scraped or worn away

How much colder was it on Earth during the Ice Ages compared to the temperature now?

large ridge of rocks and soil deposited by a glacier when it stops moving forward

Valley glaciers are thicker than some mountain ranges. t/f?

which of these is NOT a cause of erosion?

which of these is NOT a type of mass movement?
