Answer:
ENDORHEIC BASINS
Inland sea is an example of this
Answer:
A. The ice has a high albedo.
Explanation:
Albedo is a measure of ‘whiteness’ or reflectivity which is also the rate at which a surface is able to reflect a percentage of solar radiation it receives. White surfaces have a higher albedo which is why Arctic and Antarctic regions with lots of ice sheets have a high albedo. They play a big role in regulating global temperatures. The larger the ice sheet cover in the antarctic and arctic regions, the more they reflect solar radiation back to space hence keeping the temperatures on earth from rising considerably.
Farming is a common economic activity around two important rivers in South Asia, the INDUS and the GANGES
Explanation:
Ganges and Indus are two of the major rivers flowing in South Asia. They came into existence a long time ago. These rivers along with the Brahmaputra are known to be the backbone of South Asia in terms of culture and economy. The three rivers have contributed to the rise of the earliest civilizations in history.
Farming is the major economic activity in which these rivers have contributed and still contributing to the present as the soil present around them is very fertile and is ideal for various crops such as Wheat, Rice,Cotton,Sugarcane and Maize. The fertility of the soil is replenished when the rivers are flooded making it ready for next cultivation.
Answer: The probe won’t display a reading because the skull is too old. There isn’t enough carbon-14 remaining to accurately assess its age.
Explanation: change it up a bit though.
Answer:
c) No UV light until spring
Explanation:
According to research, chlorofluorocarbons also known as CFCs, are chemicals that are mainly responsible for the destruction of the ozone gas.
<em><u>This is all due to the interaction of different factors, and not only because of the presence of UV. </u></em>
In Antarctica, the ozone levels become significantly reduced during spring because of these chemicals that contain chlorine, producing a hole where cool air becomes trapped. This air produces clouds that are responsible of the release of chlorine from the CFCs, an extremely important process of the formation of an ozone hole. The more clouds there are, the more gases are released, and the worse the ozone hole will be in spring.
Because the sun rises and becomes more intense during spring, it degrades these gases and releases the free radicals of chlorine, which are highly detrimental for the ozone layer as they destroy numerous molecules of ozone. By the beginning of summer, there is a higher amount of ozone that comes from other areas which help fill the ozone hole.
