Answer:
It is called <u> </u><u>Electromagnetic</u><u> </u><u>wave</u><u> </u>
Explanation:
• An electromagnetic wave is a wave formed as a result of vibrations, or disturbances between Electric and magnetic fields.
• Examples;
- Gamma rays
- Visible light
- Ultraviolet rays
- X-rays, e.t.c
» These rays move at a speed of light in vacuum
» These rays are not affected by any fields [ Electric and magnetic fields ]
The two biggest aspects of the global climate change that impact the forests are the temperature and the precipitation. The temperature increases globally, this affects the forests because the trees are adapted on certain temperatures, but now are faced with rapid increase of the same, and the time for adaptation is much shortened, so lots of forests degrade or gradually die off. The precipitation is a crucial factor for all plants. The forests are on places where there's sufficient amount of precipitation, but now lots of regions in the world are suffering from reduced precipitation, this also causes the degrading and dying off of the forests.
The answer is B. subsistence economies
Answer:
B) The warm, moist Pacific air rises and cools, releasing precipitation as it moves up the windward side of the range, and this cool, now dry air mass heats up as it descends on the leeward side of the range
Explanation:
The air masses that have formed over the Pacific and move toward the western coast of the United States are warm and moist ones. As they reach the coastline they continue into the mainland, but only to come upon a natural barrier, a north-south mountain range. The warm and moist air starts to move up and starts to cool off, and as it does, condensation occurs, thus the windward side of the mountain range gets a lot of precipitation. The cool, but now dry air continuous its movement across the mountain range, and moves down its leeward side. As it moves down on the leeward side it heats up again, so it becomes a warm and dry air mass. This makes the leeward side very dry, so it is no wonder that it is dominated by desert and semi-desert.
