Answer:
The layer of greenhouse gases is permeable to one side and not permeable to another side.
Explanation:
Greenhouse gases such as carbondioxide, methane and water vapors etc formed a layer which allow the sun radiation to the earth surface but when these radiation reflected back, this layer traps these reflected radiation and the radiation remain suspended in air which heat up the particles present in the air and increases the temperature which causes global warming of earth surface. This phenomenon is also called greenhouse effect and it is also very useful in growing crops in cool seasons. So this layer is permeable from one side and not permeable from another side.
Yes it was formed by a glaciers.
The regions of light and unpredictable winds at about 30° No latitudes are called <u>trade winds</u>
Answer: Option A
<u>Explanation:</u>
Trade winds are the latitudes which cool and descend at 30 degree north and are areas with surface winds but these surface winds are light and unpredictable. These are the winds that blow towards the equator.
Trade winds blow at an average speed of about 5 to 6 meters per second and these winds are unpredictable. These winds are warm winds and therefore they pick up moisture and bring heavy rainfall.
Answer:
How do glaciers affect animals?
Their melting water flows into the soil which affects vegetation which acts as food for animals at lower altitudes, some of which are prey for other animals and so on. ... As glaciers melt large deposits of sediment are deposited in valleys below. This affects the local land and rivers and their existing ecosystems.
