Answer:
As the cloud shrinks in size, its central temperature increases, as a result of its gravitational potential energy being converted to thermal energy.
We are assuming that the mentioned cloud, is a cloud of interstellar dust (nebula), in which this definition is applicable. Since energy cannot disappear, the lost gravitational potential energy would have to transform into something else, in this case, thermal energy, or simply heat, which will increase the overall temperature of the cloud.
Answer:
Ice Sheet - Shrinking in a glacier
Moraine - Rock piles left by glaciers
Countour Planting - One way to prevent soil erosion
Retreating - Continent Sized
Explanation:
Ice Sheet: Shrinking of ice sheets in a glacier is a result of the burning of fossil fuels that building up greenhouse gases in the environment and leading to global warming. When ice exposes to heat, it shrinks and melts.
Moraine: A moraine is defined as the debris or piles of rock left behind by a moving glacier.
Countour Planting: Contour farming or planting is a farming technique in which plants are grown in row patterns across a slope following its elevation contour lines. It prevents soil erosion by capturing at least twice the rainwater.
Retreating: Retreating is the process in which either ice melts or erode. Continent size can be affected by the retreating ability of glaciers.
Hence, the correct answer is:
Ice Sheet - Shrinking in a glacier
Moraine - Rock piles left by glaciers
Countour Planting - One way to prevent soil erosion
Retreating - Continent Sized
If you are talking location wise, it would be that the place were the port is being built is located near a body of water or water way.
