Which of these may decrease temperatures by reflecting sunlight back into space? Choose the correct answer. O global warming
O orbital change
O sea-level change
O volcanic activity

volcanic activity

Explanation:

during volcanic activity ash is produced and it causes the decrease in temp by reflecting the rays to space

if there is a change in sea level the temp would either drop or rise .this is because the earth is spherical hence the sun shines more at the equator hence the polar areas do not receive much sunshine .the oceans in the equatorial areas carry out a lot of evaporation making sure the environment is cool

global warming is the change in the climatic conditions in which the season are mixed up and there are less rainy seasons hence the temp rises
