Which of the following is true of creep?

it happens too slowly to be seen

it c\occurs faster when the soil is dry

a type of mass movement that you are least likely to see

it always occurs at the same rate

What is true of rockfalls but not rockslides?

individual blocks of rock drop suddenly down a slope

rockfalls often take place in high mountains

a large mass of rock slides as a unit down a slope

rockfalls are an example of mass wasting of rock

Which is NOT true of mudflows?

it is an example of mass wasting of rock

it consists of debris with large amounts of water

it can occur in mountain canyons and valleys after heavy rai

it can occur on active volcanoes

Which is true of mass wasting?

it can be triggered by heavy rain or earthquakes

it only occurs in tropical climates

it often takes place on flat lands

it never occurs gradually

What can happen after a mountain slope collapses?

it can cause mass movements of debris

it can cause telephone poles to lean slightly

it can form a volcano

it can cause an earthquake

Which is NOT a type of mass wasting?

blizzards

mudslides

creep

rockslides

Which mass wasting is the slowest?

creep

rockslide

slump

mudflow

Which is evidence of creep?

leaning fences

sudden movement of rocks

large amounts of mud flowing down a mountainside

volcanic eruptions

What makes up debris?

soil, rocks, plants

soil, rocks, and ice

water and soil

water, soil, rocks, and plants

Which can cause mudflows?

volcanic eruptions

ice loosening rocks

construction of highways making slopes unstable

wind pushing on loose rocks

What kind of terrain do landslides, rockslides, and mudflows all occur on?

mountainsides

flat land

canyons

volcanoes

Why are the coastal regions of California dangerous?

There are lots of landslides

The creep there is fast moving

There are lots of mudflows

The cliffs are unstable

Which is NOT one of the main three ways erosion moves sediment?

rock

wind

water

ice

What can bad farming practices lead to?

soil loss

overpopulation

increase in predators

loss in flavor

What is soil used for?

all of these

to support th growth of plants

to purify water

to shelter animals

How is texture of the soil determined?

the size of the weathered rock particles

the pore space

the amount of water

the amount of air

How do microorganisms help plants?

they provide plants with nitrogen

they provide plants with carbon dioxide

they provide plants with water

they provide plants with oxygen

Which is NOT a part of soil?

fertilizer

humus

air

water

Which kind of climate speeds up chemical weathering?

hot

mild

chilly

cold

Which reacts with rain water to help dissolve rocks?

carbon dioxide

water

oxygen

rust

Which is NOT a form of mechanical weathering?

dissolving

ice wedging

abrasion

pressure release

A lot of soil is dug up at construction sites. What can this lead to?

the soil can go into rivers and lakes and cause flooding

the soil is brought to farms to replace old soil

the soil is used to keep buildings in place

the soil is thrown out

In dry regions, what can overgrazing and clearing of land for farming lead to?

desertification

crop rotation

plowing

tillage

How do windbreaks help conserve soil?

they stop wind from blowing away soil

they block sunlight from destroying soil

they stop water from draining out

they keep animals away

What is similar about terracing and contour plowing?

they both are used on sloping land

they both reduce the amount of plowing

they both include trees

they both use different crops to conserve nutrients

Which is NOT a method of conserving soil?

desertification

crop rrotation

contour planting

windbreaks

What happens with the soil when strip mines are dug?

plants and soil are removed

soil is moved but then put back when done

soil is moved to a previous mining spot

soil is not affected

Which human activity does NOT directly affect soil?

hunting

mining

construction and development

farming

Why is soil an important resource?

helps plant growth, purifies water, and recycles nutrients

it helps create farms

it helps fill in space for development

it is food for animals

landslide

a sudden fast movement of rock and soil

the downhill movement of masses or rock and soil

when sediment is put in a new location

weathered particles are picked up and moved to another place

mass wasting

the downhill movement of masses or rock and soil

a sudden fast movement of rock and soil

when sediment is put in a new location

weathered particles are picked up and moved to another place

deposition

when sediment is put in a new location

weathered particles are picked up and moved to another plac

the downhill movement of masses or rock and soil

a sudden fast movement of rock and soil

erosion

weathered particles are picked up and moved to another place

when sediment is put in a new location

the downhill movement of masses or rock and soil

a sudden fast movement of rock and soil

contour plowing, strip-cropping, and terracing are conservation methods made to reduce the

runoff water

activity of microorganisms

acidity in soil

pore space in soil

What is the main component of soil?

humus

air

water

rock particles

The breakdown of rock by acidic water is an example fo

chemical weathering

mechanical weathering

oxidation

desertification

windbreaks

planting trees between fields to reduce soil carried off

plowing along curves or contours of slopes

flat, steplike areas built on a hillside to hold rainwater

when sulfide minerals react with air and water

contour plowing

plowing along curves or contours of slopes

flat, steplike areas built on a hillside to hold rainwater

when sulfide minerals react with air and water

reduce number of times soil is tilled
