Earth's atmosphere is composed mostly of nitrogen and oxygen. in order to float, a ballon has to be filled with something that is lighter than air. use the information on the periodic table too find out which elements might be suitable for making a ballon float. explain your choice or choices.
2. All of the frozen water on Earth is found in the A. cryosphere (Cryo- means ice)
3. The hydrosphere is composed of B. all the water and water vapor on Earth (Hydro- means water)
4. The geosphere is composed of C. all of the solid, rocky part of the Earth (Geo- means earth)
5. The atmosphere is composed of C. all the gases that surround the Earth (Atmo- means air/gasses)
I hoped this helped the only one i'm not sure of is 4!
2. D. Ozone absorbs ultraviolet radiation
3. I would guess A. heat from the Earth's core but I'm not completely sure
Atmosphere is made up of air, hydrosphere contains all living things, Evaporation is necessary to water circle while precipitation is not always necessary and the amount of water on earth never changes but the state could.
The biophysical elements of the earth are divided into four spheres which include biosphere, lithosphere, hydrosphere and atmosphere.
The biosphere is the biophysical element that contains living things/organisms.
The lithosphere is the sphere that contains the land or soil.
Hydrosphere is the biophysical element housing the waters while atmosphere contains the air including all its components like oxygen, carbon dioxide, neon amongst others.
As regards the difference between evaporation and precipitation, Evaporation has to do with the change in state from liquid to gas especially as it concerns water and it’s very important to the water circle while precipitation refers to the process whereby it falls off from the sky eg rainfall but it’s not really necessary for the water circle.
As for the last question (8), the amount of water available is always constant but can change states ie from solid (ice) to liquid to gas
1. is A. soil
And the last one I would go with is remains the same just in different forms tbh
A. friction from landscape features doesn't slow them down.
I just took the TEST and made a 100%, It was right.
Answer 1: Option(B) Nitrogen
The earth's atmosphere comprises of different gases which are Nitrogen(78%), plenty of Oxygen(21%), argon(0.9%) and remaining are the methane, gaseous oxides etc. So Nitrogen is present in largest quantity in the earth's atmosphere.
Answer 2: Option(D) Ozone
The Stratosphere is the second lowest layer of the earth. It contains the ozone which absorbs the UV rays coming form the sun because of which there is a rise in temperature than other layers.
Answer 3: Option(A) Heat from the earths core
The heat energy coming from the Sun heats the earth non-uniformly that results in the hot and cold area on the earth causes low and high air pressure.The Sun heats the earth core. When there is a hot weather the land near the sea becomes hot in comparison with the sea results in the hot wind flow from the sea.
As explained below.
Explanation:As the martin air composed of 96% of carbon dioxide and some parts of methane but this greenhouse effect is much less as compared to that of the earth as on earth the greenhouse gases are not as rugged and as profound as they are on the martian surfaces and hence they are more intact and well produced in mars dry and rocky environment. The more is the greenhouse gas concentration the more is the planets lots of co2 is wrapped in the oceans and ice layers that are trapped into the air keeping the air warm and dry. Having a thin and less dense atmosphere than the earth this planet experiences drastic temperature changes thus the greenhouse effects are less profound on earth. Mars experiences frequent temperature changes and dense storm surges also.
B. Composed of molecules relatively far apart.
The gas we call "air" has molecules that are relatively far apart.
is the correct one
covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
the answer would be a
