I dont understand this questions for earth science?

Question

Hot air rises and cool are sinks? true or false

2. The stratosphere contains all the clouds. T or F

3.The water cycle is also knowns as hydrologic cycle?
TRUE OR FALSE


thanks =) i am stuck with 3

Answer 1

Look it up!

Answer 2

Hot air rises and cool are sinks? true or false
That is true... Hot air is less dense so it rises, cold air is more dense, so it sinks.

2. The stratosphere contains all the clouds. T or F
False... Stratosphere is too flat and very stable, temperatures rises above the stratosphere.

3.The water cycle is also known as hydrological cycle?
TRUE OR FALSE

This is true... It studies how the water is evaporated into the atmosphere and fall back to earth as rain.

Answer 3

Well, go to dictionary.com and look up the word "stratosphere" and "hydrologic" -that should help you understand their meanings.

As for hot and cold air- I don't know why, lol, but, the answer is, hot air rises. I feel like I'm cheating just a little by just handing you the answer, but, what the hay. You should, though, look up why hot air rises, so that you better understand the material- it would be more beneficial, I think, for you to learn, rather than not learn :P

Answer 4

Hot air rises and cool sinks. True

The stratosphere contains ozone, not clouds. The troposphere contains all weather and clouds. 2 is false.

I am pretty sure 3 is true. It sounds like water.

Answer 5

1. It is true, and this is how they make winds.
2. Only a very small amount of clouds are in the stratosphere. Jets fly there at high speeds
3. True - I think. Each molecule of water contains two atoms of hydrogen and one atom of oxygen. That is why it is called H2O.

Answer 6

1Weather is the day to day things like rain and cloudy, Climate is over the course of years for example the climate in Florida is warm and humid. 2 The earth revolves around the sun causing a different amount of light and heat to reach an area. 8 Like in a greenhouse the heat comes in but stays inside the earth instead of leaving it will warm up the earth. 9 Humidity is the moisture content of the air compared to how much it can hold. Relative humidity takes into consideration how much humidity the air can hold. When it becomes cold the air can hold less so that is taken into consideration 10 The colder it gets the less it water it can hold 14 Hail, frozen ice balls Snow, frozen water mixed with air rain, liquid water Sleet, water that frozen in the atmosphere and is in the process of melting 15 Condensation, Water in the air (water vapor) is clinging to the cold surface of the bottle. Same way clouds form That isn't all the questions but hope it helps

Answer 7

Hot air does not rise because it is hot nor does cold air sink because it is cold. Less dense air rises, denser air sinks. If you climb through the troposphere, the air temperature gets lower, there is cold air overlying warmer air yet the warm air doesn't rise into the colder air. This is because the warm air close to the ground is denser than the cool air above it.

Hot air will be less dense than cooler air at the same level and air pressure but it is not temperature alone that determines the density of the air.

The correct answer to "hot air rises, cool air sinks" is False. The correct statement is "less dense air rises, denser air sinks".

Answer 8

1 True
2 False
3 True

Answer 9

1. T
2. ?
3. T

I have a Bachelor's degree in Biology and remember Q's 1 and 3 from classes but I do not remember if #2 is T or F. I suggest doing a search on the internet.

Answer 10

True. As weird as it sounds, my stepbrother used to fart around me and my step sister when we were on the bunk bed (top) and he was on the bottom. Hot air rises so we always used to jump off and run for it.
false. The atmosphere
true. Hydro means water. That helps me out.

Answer 11

1. true
2.false, some types of stratus clouds (fog) are near the ground
3. true
