Map Test Review - Set 5

Front 1

The Measure of Heat is called: _______________

Back 1

Temperature

(The measure of hotness or coldness, or how fast molecules move around is called temperature)

Front 2

The transfer of energy from one part of a substance to an other:

Back 2

Heat

Front 3

Heat ALWAYS flows what direction?

Back 3

Heat always flows from a higher temperature to lower temperature (raising the temp of the cold substance, and lowering the temp of the warm substance)

Front 4

When hotness (or heat) increases, the molecules of a substance go faster or slower?

Back 4

Molecules go faster (and expand) as heat increases

Front 5

The weight of air pushing down on us is known as:

Back 5

Air Pressure

(The more air above us pushing down, the more the air pressure will be)

Front 6

At greater heights, there's (more or less) air pressure??

Back 6

Less

(At greater heights, there's less air pressure becaue there's actually less air the higher up above us weighing down on us).

Front 7

Air pressure can change with __________________.

Back 7

Temperature

(Warm air rises, resulting in lower pressure. Cold air sinks, resulting in higher pressure. When low pressure moves in it will bring stormy weather. High pressure will usually bring good weather).

Front 8

_________________ is created when there is a difference in air pressure from one area to another.

Back 8

Wind

(Wind is created when there are differences in air pressure from one area to another. The air will blow from high to low. If a high and low pressure area are close to each other, a strong wind will develop because a natural circulation of air will occur. The greater the difference in pressure, the stronger the wind will be).

Front 9

The process of being eroded by wind, water, or other natural agents is called _________________.

Back 9

Erosion

(Erosion is the process of being eroded by wind, water, or other natural agents).

Front 10

When rocks are broken down into progressively smaller pieces by weather it's called: ______________________.

Back 10

Weathering

(Weathering takes place as rocks are broken down into progressively smaller pieces by the effects of weather. when weathering happens, the pieces don't move but they simply break down.

Front 11

Explain the difference between weathering and erosion:

Back 11

Once small pieces of rocks are changed or broken apart by weathering, they start to move by wind water, or ice. When the smaller rock pieces (now pebbles, sand, or soil) are moved by these natural forces, it is called erosion. Weathering the actual breaking down of rock. Erosion involves the movement of the broken down pieces.

Front 12

Some rocks are broken down so much that they become ___________________.

Back 12

Dirt/Soil

Front 13

Weathering is caused by _________________ as it freezes and thaws.

Back 13

Water

(Weathering is caused by water as it freezes and thaws, as well as by chemical reactions that loosen the bonds holding rocks together. There are microscopic spaces between the grains of rock. Water gets into these spaces and loosens the bonds in rock).

Front 14

_________________ weathering is the physical breaking down of rock (not a chemical process).

Back 14

Mechanical

(In mechanical weathering, rocks are torn apart by physical force, rather than by chemical breakdown. It is most often the result of constant freezing and thawing of water, which expands causing the holes and cracks in rock to push even further apart).

Front 15

__________________ weathering is when chemical reactions break down the bonds holding rocks together.

Back 15

Chemical

(Chemical weathering happens when chemical reactions break down the bonds holding rocks together).

Front 16

___________________ weathering is caused by living organisms like plants.

Back 16

Biotic Weathering

(Biotic weathering happens when plant roots wedge into the rock and widen and extend cracks in rock. Other sources of biotic weathering include digging animals, plants, algae, and fungi).
