Exercise A: Global Temperature and Precipitation Patterns
Solar Angle of Incidence
Nearly all of the biomes on Earth are dictated by two factors: the amount of temperature and precipitation they receive, and these are correlated. Temperature on Earth is dependent on the solar angle of incidence, or the angle at which the light waves from the sun hit the surface of the earth. Areas of earth that are perpendicular to the sun's rays receive more energy than other parts where the sun's rays hit the earth at an oblique angle. Over one year, the equator receives the most amount of light energy from the sun per area; whereas the poles receive the least. At the middle latitudes there is a moderate angle of incoming light, creating moderate temperature. Solar angle of incidence is the primary determinant of global temperature patterns.

Step 1

This is because the equator receives maximum sunlight due to being perpendicular to the sun's rays, while the poles receive less sunlight. Therefore, temperature and latitude are inversely related. ** Show more…

00:01 In this question, we have to draw a line on each graph.

00:07 So here we have to draw a line on each graph so that the particular line it indicates the relationship between the temperature, water holding capacity, water holding capacity, as well as air mass density, air mass density, as well as latitude and altitude.

00:34 Altitude and latitude latitude latitude so the particular line whatever we are drawing in the graph that particular line it makes or it indicates the relationship between the temperature water holding capacity air mass density latitude and altitude so we'll see here first they have given that so on x -axis they have given the latitude and on by axis they have given the temperature so this is the low temperature and it is a high temperature and the latitude 0 to 90 degrees.

01:11 So the line here, the graph here it is the this is the graph.

01:16 The line, this is the line.

01:20 So what it indicates? so here, here particular, this is the temperature latitude graph.

01:30 So the graph here it is the first graph that is temperature latitude graph.

01:35 Latitude graph.

01:36 So what it will what this particular graph represents as the latitude it changes from 0 to 90 degrees centigrade, that is from equator.

01:47 This is at the equator to the poles.

01:51 So what happens? the temperature here, the temperature, whatever the temperature, as the temperature it decreases as equator.

02:09 So what happens? the temperature is the temperature.

02:10 So what happens? the temperature is.

02:12 It becomes decreases.

02:14 So whenever it move from the equator to the pools, the temperature decreases.

02:22 Here the temperature decreases.

02:25 As the equator gets the maximum sunlight.

02:29 So when the equator gets maximum sunlight, because it is perpendicular to the incident rain.

02:36 Why this graph? because the temperature, decreases, the temperature decreases as the equator gets the maximum sunlight.

02:51 So the temperature decreases as the equator gets the maximum sunlight because it is perpendicular to the incident rate.

03:03 Why means? because the equator it is perpendicular to incident rate.

03:09 So here what is the reason behind this? the equator it is perpendicular to the incident rate.

03:15 And also here that it will be the less distance from sun when compared to poles.

03:24 Less distance from sun when compared to poles.

03:29 When compared to poles.

03:32 So here the poles gets here poles.

03:38 Whatever the poles are present, the poles they get less sunlight...
