Science

Question 1

Weather

Answer 1

The state of the atmosphere at a specific place and time.

Question 2

4 Components of Weather

Answer 2

Sunlight, Wind, Temperature, Precipitation

Question 3

Heat Transfer

Answer 3

The movement of heat energy from one object to another.

Question 4

Conduction

Answer 4

Heat transfer by direct contact

Question 5

convection

Answer 5

heat transfer by differences in densities in a gas or liquid.

Question 6

Radiation

Answer 6

Heat transfer by electromagnetic waves

Question 7

Atmosphere

Answer 7

The whole mass of gases that surrounds a planet

Question 8

Troposhere

Answer 8

The lowest layer of the atmoshere, where weather forms.

Question 9

Biome

Answer 9

A group of ecosystems that share similar climates and typical organisms

Question 10

Global Air Circulation

Answer 10

The world-wide system of winds that move heat from the equator to the poles.

Question 11

Differential heating

Answer 11

The uneven heating of the earth based on the earth’s position in relation to the sun.

Question 12

Air Cells

Answer 12

Large masses of air that move heat through convection

Question 13

Hadley Cell

Answer 13

The largest and warmest of the 3 air cells. Found at the equator, bringing warm air towards 30 degrees N and S.

Question 14

Mid-latitude cell

Answer 14

Also known as the Ferrel Cell. This cell runs on pressure differences rather than temperture. stretches from 30 degrees to 60 degrees N and S.

Question 15

Polar Cell

Answer 15

The smallest and coldest air cells. Found directly over the poles.

Question 16

Coriolis Effect

Answer 16

The effect of Earth’s rotation on the direction of winds and currents.

Question 17

Prevailing Winds

Answer 17

Global winds that blow constantly from the same direction

Question 18

Jet Streams

Answer 18

bands of high-speed winds about 10 kilometers above Earth’s surface

Question 19

Weather Fronts

Answer 19

A boundary between two air masses of different density, moisture, or temperature

Question 20

Cold Air Front

Answer 20

Cold air mass replaces warm air at the surface and pushes warm air higher into the atmosphere. Moves quickly because it is easier for cold air to move warm air.

Question 21

Warm Air Front

Answer 21

A warm air mass replaces cold air at the surface. Moves slower because it is harder for warm air to move cold air.

Question 22

stationary front

Answer 22

A boundary between air masses that don’t move possibly causing rain for several days

Question 23

Season

Answer 23

A period of the year characterized by particular conditions of weather, and tempature

Question 24

Equinox

Answer 24

The two days of the year on which neither hemisphere is tilted toward or away from the sun, meaning there is the same amount of daylight as night.

Question 25

Climate

Answer 25

The long-term average weather condition at a particular location, typically over a 30 year period.

Question 26

Climate Zone

Answer 26

Areas of distinct climate that form in east to west bands across the globe.

Question 27

Soltice

Answer 27

the point at which the Sun reaches its greatest distance north or south of the equator
