Answer:

"Be freezing at night because the planet has no atmosphere" is the correct answer.

Explanation:

I was doing my reading in OW and I quote this is what OW said:

Temperatures during the day can reach 430°C (800°F), but can drop to -170°C (-280°F) at night because there is no atmosphere to trap heat.

Hope I helped:)

Have a great day!!!

Temperature inversions occur naturally in the stratosphere and thermosphere, but also occur closer to the surface of earth in th
skelet666 [1.2K]

Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.  

When there is an increase in temperature with altitude that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.

So how air circulation behaves during inversion?

So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:

• As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.  

• The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.

• The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.  

• When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.

Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.

Hope it helps! :)

musickatia [10]

Answer:

C.  Oceans are carbon sinks because they store more carbon than they emit.

Explanation:

Oceans are carbon sinks because they store more carbon than they emit. Most of the carbon is produced in the respiration process as well as burning of fossil fuels. This carbon moves to the atmosphere and dissolved into the ocean which is required by the vegetation of ocean. Due to this carbon, vegetation produced more food for the organisms. About 25% of all CO2 emissions are absorbed by the ocean. Source is the part of a plant where materials are produced e.g. leaves whereas Sink refers to the part of the plant where the substrate can be stored e.g. roots or stem for starch.
