Science unit 3 test

Which of the following processes transfers the Suns energy between particles as well as through empty spaces?

Radiation only

What three methods identifies energy transfer

Radiation, convection, conduction

In which of these three substances will convection happen least efficiently

Rock

What is the percentages of the nitrogen, oxygen, and other

76% nitrogen, 23% oxygen, 1% other

Consider the following three substances: a rock, a pool of water, and a section of air. In which substance will convection happen most efficiently?

A section of water

What is it called when warm air rises

A valley breeze

What is not a way in which energy is transferred to earth from the sun?

Conduction

What is responsible for the moving bands of air around earth

Convection

Conduction happens as energy flows fro, a warmer object to a cooler object. Which is an example of conduction

Cooler air molecules come in contact with warm ground , causing energy to be passed to the air

Earth's atmosphere traps energy from the sun. Which is a direct result of the trapping of energy by earth's atmosphere

Earth has moderate temperatures

Differences in air pressure drive the global wind systems on earth. Which term describes polar ones that blow from east to west?

Easterlies

A plastic spoon that has a tempature of 78 degrees F is placed into a bowl of soup that has a temperature of 84 degrees F. What will happen

Energy as heat moves from the soup to the spoon

What statement describes the energy transfer that happens in Vivian's investigation?

Energy in the form of heat is transferred from the water to the ice cube by conduction.

T/F- the stratosphere is the top layer of earth's atmosphere

False

T/F-radiation is a measure of the average kineric energy of the particules in an object

False

T/f- a jet stream is a wide band of low speed winds that flow in the middle atmosphere

False

The global movement of air occurs in convection cells. In general, how does air move?

From areas of lower pressure to areas of higher pressure

The Coriolis effect is the curving of the path of a movie object in earth's atmosphere that is causing by earth's rotation. How does the Coriolis effect affect winds globally?

It causes an apparent change in wind direction.

In what weather does weather happen?

Layer 1

What gas has the largest amount in earth's atmosphere

Nitrogen

Describe sea breezes

Occurs during the day and blows toward the land

Explain how earth gets energy from the sun and what the atmosphere does with that energy to help life survive on earth.

Sun radiates heat, atmosphere either absorbs or reflects it. The energy in the form of heat and prevents from freezing, it provides plants and animals which humans each so without it we would die.

What explains the curvature of the arrows for the westerlies and the trade winds

The Coriolis effect causes the winds to curve that way because earth rotates from right to left.

The atmosphere is the boundary between earth's surface and outer space. What is the atmosphere

The layer of gases that surrounds earth

What is convection

The transfer of energy due to the movement in matter

Name the four atmospheric layers

Troposphere, stratosphere, mesosphere, thermosphere

T/F- thermal expansion is the increase in volume that results from an increase in temperature

True

T/f- the curving of the path of a moving object as a result of earth's rotation is called the Coriolis effect

True

How would the air temperatures above the land compare to the air temperatures above the water during a cold winter along this same coastline

Upstanding effects of specific heat to absorb or understand energy

During a hot summer air temperatures along a coastline are higher above the land than they are above the land than they are above the water even though both the land and sea receive the same amount of solar energy. What causes this temperature difference.

Water has bigger specific heat than land

At different places on earth, depending on elevation, air pressure varies. What causes air pressure?

Weight of air.

What describes the general pattern of winds near the equator

Winds are generally weak because the equator is a region of mostly low air pressure
