$100 Question from H1

the average weather conditions inAn area over a long period of

time

$100 Answer from H1

Climate (Temperature)

$200 Question from H1

The height (typically measured in feet above sea level) to

which something is elevated or to which it rises

$200 Answer from H1

Elevation

$300 Question from H1

The more _______ _____ of a rock that is exposed to weathering, the faster the rock will wear down.

$300 Answer from H1

Surface Area

$400 Question from H1

Rocks that are made of ______ minerals will weather faster than rocks that are made of _______

minerals.

$400 Answer from H1

Softer, harder

$500 Question from H1

A process by which softer, less-weather resistant rock wear away and leave harder, more weather-

resistant rock is called…

$500 Answer from H1

Differential Weathering

$100 Question from H2

Rain, snow or sleet that contains a high concentration of acids (an agent of chemical weathering)

$100 Answer from H2

Acid Precipitation

$200 Question from H2

These are agents of chemical weathering (name three)

$200 Answer from H2

Water, weak acids/plant Acids, air

$300 Question from H2

What causes acid precipitation

$300 Answer from H2

The burning of fossil fuels

$400 Question from H2

a chemical reaction in which an element, such as iron, combines with oxygen to form an oxide.

This form of chemical weathering forms rust.

$400 Answer from H2

Oxidation

$500 Question from H2

Another name for living things such as algae or

fungus (which live on rocks) which produce acids that slowly break down rock.

$500 Answer from H2

Lichens

$100 Question from H3

The grinding and wearing away of rock surfaces through the mechanical actions of other

rocks or sand particles

$100 Answer from H3

Abrasion

$200 Question from H3

These are agents of Mechanical (Physical) Weathering (list at

least 4)

$200 Answer from H3

ice, wind, water, gravity, plants and animals

$300 Question from H3

An agent of mechanical weathering that causes rocks to fall (rock

slide/landslide) causing abrasion as they hit each other

$300 Answer from H3

Gravity

$400 Question from H3

When water seeps into cracks during warm weather, temperatures drop, water freezes and expands pushing

against the sides of the crack (pressure), widening the crack until

the rock breaks up/apart

$400 Answer from H3

Ice Wedging

$500 Question from H3

Describes how a rock changes after it has been in a riverbed for

a long time

$500 Answer from H3

the edges of the rock are worn away and its surface becomes smoother

$100 Question from H4

The process by which wind, water, ice or gravity transports soil and sediment from one location to

another

$100 Answer from H4

Erosion

$200 Question from H4

The process in which material/minerals are laid down

after being carried away

$200 Answer from H4

Deposition

$300 Question from H4

The process by which rock materials are broken down by the

action of physical or chemical processes

$300 Answer from H4

Weathering

$400 Question from H4

What agent of weathering can weather rock mechanically and

chemically?

$400 Answer from H4

Water

$500 Question from H4

Name four factors that affect how fast weathering happens

$500 Answer from H4

Temperature, moisture, Elevation and slope

$100 Question from H5

The roots of plants canGrow deep into cracks and cause

Mechanical weathering

$100 Answer from H5

True

$200 Question from H5

Elevation and slope can affectHow fast weathering occurs

$200 Answer from H5

True

$300 Question from H5

Rocks with very little surface area weather faster than rocks

With a lot of surface area

$300 Answer from H5

False

$400 Question from H5

Temperature is a major factorIn both chemical and mechanical

weathering

$400 Answer from H5

True

$500 Question from H5

In chemical weathering, the chemical composition of

A rock does NOT change.

$500 Answer from H5

False
