The use of CFCs <span>does not contribute to increased air quality. </span>
Answer: A. Air bubbles trapped in a layer indicate how much CO2 was in the atmosphere the year the layer formed.
Explanation:
When ice cores were formed, they included air bubbles that got stuck during the formation. Scientists can study these air bubbles to find out how much carbon dioxide is in them as this will show the proportion of carbon dioxide in air at the time the core was formed.
They can then compare those figures to current carbon dioxide levels to see if there has been a change. This change will give proof of climate change.
Answer:
C. Tropical wet
Explanation:
On the map we can see the region known as Central America. It is representing the climate regions in this region, each of them represented with different color.
Out of the four suggested climate types, the only that can be found in this region is the tropical wet climate type. This climate type is found in the areas marked with the number five and with dark pink color.
The tropical wet climate type is characteristic by having constant summer all year long. The temperatures are constant and there is very small variations in them. The amount of precipitation is very high and it falls throughout the majority of the year. The landscape is covered with tropical rainforest, and there is an abundance of flora and fauna.
