Why are density currents found closer to the arctic and antarctic regions?

Only water freezes in the icecaps. Salty dense water sinks.

One property of water is its high heat capacity. Why is this significant to climate?

Weather by large bodies of water doesn't change drastically

How would the earth be different without greenhouse gases in the atmosphere?

The earth would be cooler and uninhabitable in most areas.

Are the greenhouse effect and global warming the same thing?

No. The greenhouse effect is a natural process

Which of the following statements is TRUE?

C cycles among hydrosphere, atmosphere, geosphere, biosphere

How do greenhouses gases keep the earth warm?

They absorb heat re-radiated from the earth.

How can ocean currents affect the climate of land areas?

Land near warm water currents are often warmer and wetter.

How does carbon dioxide enter the atmosphere?

Naturally, like respiration, and humans, like burning fuels.

How is upwelling beneficial to marine organisms?

Water that rises is rich with nutrients and food.

Thermohaline circulation is the term for global ocean circulation. Which statement is true?

Cold water sinks, and saltier water sinks.

Answers

1
Why are density currents found closer to the arctic and antarctic regions?
The wind blows currents from the equator toward the poles.
Only water freezes in the icecaps. Salty dense water sinks.
Water freezes. Since ice is a solid, it's denser and sinks.
When the water hits the ice, it has nowhere to go but down.
2
One property of water is its high heat capacity. Why is this significant to climate?
Water expands when it freezes so glaciers take up more space
Light can move through the water, which allows life to exist
Water's good at breaking materials down & transporting them
Weather by large bodies of water doesn't change drastically
3
What are the most abundant greenhouse gases?
sulfur dioxide and nitrous oxide
ozone and sulfur dioxide
water vapor and carbon dioxide
carbon dioxide and carbon oxide
4
What features can form along the shoreline when wave activity causes sediments to be removed?
depositional features
spits
barrier islands
erosional features
5
How would the earth be different without greenhouse gases in the atmosphere?
The environment would be healthier.
The earth would be much safer.
The earth would be cooler and uninhabitable in most areas.
Plants would reproduce more quickly and would be larger.
6
Where's the Gulf Stream located?
Pacific Ocean
Mediterranean Sea
Atlantic Ocean
Arctic Ocean
7
A current moving a large volume of water in the lower 90% of the ocean is called what?
surface current
deep current
cycle current
pynocline
8
Are the greenhouse effect and global warming the same thing?
Yes, they are the same thing.
No. The greenhouse effect is a natural process
No.The greenhouse effect occurs when heats released to space
No. Global warming is a natural process
9
Which of the following statements is TRUE?
C stays in the atm & functions only to cause global warming.
Carbon does not enter the hydrosphere.
C enters the geosphere thru photosynthesis and respiration.
C cycles among hydrosphere, atmosphere, geosphere, biosphere
10
What is the ultimate source of energy that creates our weather?
the sun
the atmosphere
the mountains
the oceans
11
What types of features can form along the shoreline when wave activity leaves sediments?
wave-cut cliffs
sea stacks
depositional features
erosional features
12
Because of the Coriolis Effect, which direction do water currents move in the northern hem?
it depends - sometimes left and sometimes right
to the left, or counterclockwise
whichever direction the wind is blowing
to the right, or clockwise
13
How do greenhouses gases keep the earth warm?
They trap heat from the sun so it doesn't reach the earth.
They intensify the energy from the sun’s rays.
They absorb heat re-radiated from the earth.
They react with each other, producing heat
14
How can ocean currents affect the climate of land areas?
Land near warm water currents are usually cooler and wetter.
Land near warm water currents are usually warmer and drier.
Land near warm water currents are often warmer and wetter.
Ocean currents cannot affect climate.
15
How does carbon dioxide enter the atmosphere?
sedimentation in oceans
Naturally, like respiration, and humans, like burning fuels.
waste from animals
photosynthesis & respiration
16
Which of the following start water moving in currents, which redistributes energy around Earth?
temperature and salinity
coriolis effect and gravity
solar heating
added salinity from freezing water and wind
17
How is upwelling beneficial to marine organisms?
It keeps water at the right temperature for survival.
Water that rises is rich with nutrients and food.
It creates a path that helps animals travel.
Sometimes animals get tired, and upwelling keeps them afloat
18
Thermohaline circulation is the term for global ocean circulation. Which statement is true?
Cold water sinks, and saltier water sinks.
Warm water sinks, and saltier water sinks.
Warm water sinks, and saltier water rises.
Cold water sinks, and saltier water rises.
19
__ is the state of the atm at a given time, while __ is conditions based on data of many years.
Climate, weather
Stratosphere, thermosphere
Temperature, climate
Weather, climate
