Answer:
C. include global warming, which is greatly enhanced by society's production of greenhouse gas
Explanation:
Human activities such as burning of fossil fuel, industrial waste has lead to the emission of greenhouses such as carbondioxide, carbon monoxide, methane, chlorofloro carbon accumulation of which in the atmosphere leads to global warming as a result of the depletion of the ozone layer and the direct impact of sun on the earth.
The depleted ozone layer has lead to the constant and high temperature
that is affecting the earth.
Green plant,trees are natural users of carbondioxide but deforestation of this trees has also reduce the use of carbondioxide making it abundant in the atmosphere.
Answer:
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy
Explanation:
Answer:
True
Explanation:
The mass movements are representing movements of large masses of soil, also including rocks, water, biomass in them. These movements though need certain natural conditions so that they can happen. For a mass movement to occur, there has to be a slope, and under the influence of the gravitation, once the conditions are right, there will be movement downward until it reaches a flatter spot. If the terrain is flat, then a mass movement can not occur, as the gravitation is pulling the material down, so it will not be able to move. Also, if the gravitation is lacking, the material will not move anywhere, as without gravitation, there will be no atmosphere, and without atmosphere, there will be no agents to cause the mass movement.
