1. Draw how the intensity of the sun's rays have an impact on temperature.

Answer explanation

◼Places in low latitudes (near equator) have higher temperatures because they receive vertical DIRECT sunrays and hence more concentrated sun rays over a small area.

◼Places of higher latitudes (North Pole) have lower temperatures because they receive slanted rays which are less concentrated, spread over a larger area. Sun’s rays also travel a greater distance to reach regions near the Poles.

◼This is also because the Earth is tilted at 23.5° on its own axis. 

Which of the following is an accurate description of altitude and its impact of temperature?

• The higher the altitude the lower annual mean temperature

• It refers to the height of point in relation to sea level

• Temperatures generally decrease by 6.5 C for every 1000 m increase in altitude

• All of the above
