Pls! and make sure you are correct on all of them due tomorrow question 2 which layer of the atmosphere has the most air pressure? exosphere stratosphere troposphere mesosphere question 3 which best explains heating by convection? air molecules touch the warm ground, heating them up. warm air rises and takes heat with it; eventually it cools and sinks. sunlight travels through space without the aid of fluids or solids. land and ocean absorb and re-emit heat from the sun. question 7 which conditions are usually the effect of a low air pressure system? clear, dry weather cloudy, wet weather cold, dry weather hot, dry weather question 8 what would cause rain showers to continue over a particular area for several days? a high-pressure system a stationary front low humidity a warm front question 9 what effect does an ocean have on the climate? rushing water from tides lead to dry air. there is no influence on climate from an ocean. cool ocean air causes a cool climate. warm ocean air causes a dry climate.

Question 2) Troposphere. This is in fact the layer of atmosphere closer to the ground, and therefore it is the layer with most air above it, therefore it has the largest atmospheric pressure. Indeed, atmospheric pressure decreases as going higher in altitude.

Question 3) Warm air rises and takes heat with it; eventually it cools and sinks.This is exactly what occurs in heating by convection, not only with air but with every fluid: the warm fluid goes up and releases its heat, cooling down and becoming cold fluid and then going down again.

Question 7) Cloudy, wet weather.A low-pressure system is an area with lower pressure than the surrounding areas. Because of this, it is generally associated with the formations of clouds, and consequently precipitations (so, wet weather).

Question 8) A stationary front. A stationary front occurs when a pair of air masses point into two opposite directions. This system tends to remain in the same postion for a long time, leading to clouds and precipitations.

Question 9) Cool ocean air causes a cool climate. In fact, if wind blows from the ocean to the land, it brings the cool air from the ocean to the land, causing cool climate.
