In a high-pressure system, a. air molecules are far apart and pressing on earth’s surface. b. air molecules are far apart and rising away from earth’s surface. c. air molecules are close together and pressing on earth’s surface. d. air molecules are close together and rising away from earth’s surface.

High-pressure means that the molecules of a substance will be compressed (pushed closer together). A high-pressure system forces the molecules against whatever surface is closest to them.

Therefore, the answer is C.

The correct answer is option c. air molecules are close together and pressing on Earth's surface.

Explanation:

The weight of air that exists on the atmosphere and that is around us is called air pressure.

If this air is in a high position of the atmosphere, this pressure will decrease, because there are fewer air molecules above, so they exert less weight and less pressure.

This pressure will not be the same every day, because the Sun does not always heat the Earth in the same way. Since the hot air rises, the places where there is greater warming by the sun will have low pressure.

In a low pressure system, the center has the highest concentration of low pressure, more than the surrounding area.

And in a high pressure system, the center will have a higher concentration of high pressure. This means that the wind blows away from high pressure, swirling in the opposite direction to a low pressure system.

This type of air pressure will be determined by temperature and pressure.

materials water oxygen those are the things i can think of in this moment.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
