Unit 3

Question 0

What is the cause(s) of rising sea levels?

Answer 0

Thermal expansion ( water expands as it is heated resulting in it taking up more space) melting of glaciers.

Question 1

What is the relationship between carbon dioxide emissions and the global temperature over the last 120yr?

Answer 1

As carbon dioxide emissions increases the global temperatures increase

Question 2

What are the consequences of rising sea levels?

Answer 2

Flooding, contamination of fresh water supplies by seawater, erosion of beaches and shorelines along the ocean and coast, harm coastal ecosystems

Question 3

What happens to the rate of evaporation the oceans as the earths temperature continues to increase over the years?

Answer 3

It increases

Question 4

What consequences could the rate of evaporation of the ocean change and bringing

Answer 4

Increased precipitation in areas that are normally dry, flooding, increased cloud formation thunderstorms, hurricanes

Question 5

What ate consequences of global warming?

Answer 5

Melting sea ice rising sea levels changing growing seasons resulting in less food availability flooding increased sever weather more infectious diseases

Question 6

What is the green house gas effect?

Answer 6

The warming of the earth due to an atmosphere it is defined as warming of the earths surface by gases that reflect heat back down to the planet rather than allowing it to escape into space

Question 7

Is the earths greenhouse gas effect always a bad thing? Why or why not?

Answer 7

No, it is not always a bad thing earth would be much cooler and many lifeforms would not exist without earths greenhouse effect

Question 8

As ice caps in the polar regions continue to melt what happens to a global global temperatures

Answer 8

Are global temperatures rise

Question 9

Why do our global temperatures rise when ice melts

Answer 9

Ice reflect sunlight as ice caps melt there is less ice to reflect the sunlight sore ocean absorbs at this causes the ocean temps to rise and intern our global temperatures rise also

Question 10

Name the greenhouse gases

Answer 10

Water vapor, carbon dioxide, methane, ozone, nitrous oxide

Question 11

Why are they called greenhouse gases

Answer 11

They absorb going thermal radiation from earth. This absorption causes the atmospheric temperatures to increase

Question 12

Explain the difference in the yearly average temperature range of a city located close to the water compared to a city located completely in Land

Answer 12

A city located close to the water has a fairly small yearly average temperature range (fairly consistent temperature all year) because water heats up and cools down slowly due to its high heat capacity; a city completely in Land has a larger yearly average temperature range because land heats up and cools down quickly due to its low heat capacity

Question 13

How does latitude affect the locations average yearly temperature range

Answer 13

It location has a lower latitude ( closer to the equator) Will have a different average yearly temperature range then a similar location at a higher latitude(close to the poles)

Question 14

It’s a coastal city has a cold current running past it, how would this affect the climate of the city?

Answer 14

It will bring a cool dry air to the area

Question 15

It’s a coastal city has a warm current running past it, how would this affect the climate of the city?

Answer 15

It will bring a warm, moist air to the area

Question 16

What direction do the ocean currents flow in the northern hemisphere?

Answer 16

Clockwise

Question 17

What direction do the ocean currents flow in the southern hemisphere?

Answer 17

Counter clockwise

Question 18

Which way do the warm equilateral currents flow

Answer 18

Towards the poles

Question 19

Which way do the cold polar currents flow

Answer 19

Towards the equator

Question 20

Which heats and cools faster? Land or water

Answer 20

Land

Question 21

What causes the difference in heating and cooling between these two mediums?

Answer 21

Land has a lower heat capacity than water water has a high heat capacity, so it heats up slowly but hold onto its heat longer and Land water cools slowly

Question 22

What happens at a low pressure center

Answer 22

Air is circling in ward and converging

Air is rising

Question 23

What forms at low-pressure centers due to the movement of air

Answer 23

Clouds

Question 24

What happens on the Windward side of a mountain

Answer 24

Air is forced up the mountain into the atmosphere where the air cools, water vapor condenses and clouds are formed

Question 25

What happens on the Leeward side of a mountain

Answer 25

The cold air descends down the mountain. As it just sends it warms up and is dry air because it it can no longer hold water(it got rid of all of its moisture on the Windward side of the mountain)

Question 26

How does a tornado form

Answer 26

It forms when a thunderstorm meats high altitude, horizontal wins which cause the rising air in the storm to rotate and form a narrow, funnel-shape extension in the storm cloud

Question 27

When do tornadoes tend to form during the day

Answer 27

Late in the day when the atmosphere has had time to heat up

Question 28

Why does severe weather tend to happen in the spring in the US?

Answer 28

It is when cold, dry air from the north collides with a warm, moist air from the south(Great temperature differences in the air masses)

Question 29

Is there a season for hurricane? Why?

Answer 29

Yes because they do Jan forming in late summer and early fall because the ocean near the equator needs time to heat up

Question 30

Why is severe weather often caused by a cold front?

Answer 30

Because cold fronts usually involved in rapid lifting a warm, moist air

Question 31

What causes hail to become larger in size?

Answer 31

If the updraft is strong enough, they will process for long periods of time allowing the hail to accumulate more and more moisture

Question 32

Would a thunderstorm form by a cold front or a warm front?

Answer 32

Cold front

Question 33

Where would a heat wave most likely be happening

Answer 33

Low pressure

Question 34

Where would it hurricane most likely form

Answer 34

At a warm and cold front together
