Answer:
As the <u>temperature inversion</u> occurs around this zone
Explanation:
- Troposphere The lowest layer of atmosphere found on the surface of the earth from 0 to 30 kilometers it's wider in equator i.e 18 km and narrows at poles till 6-8 km only. At this layer, 90 % of all convective activity takes place, turbulence and cloud formation like stuff.
- Consists of 80% of water vapor and dust particles. In troposphere the temperature in the air decrease with gain in height with a height of an overall positive lapse rate of 6.5 degrees C / km. The onset of tropopause the region where mixing stops and temperature remains constant and extends up to a layer of 11 to 20 kilometers.
- However, lapse rate variation sometimes occurs in between this sphere and affects the altitude of the tropopause. The seasonal effect is strongest at the mid-latitudes and varies with changes latitudes.
The answer would be B- Precipitation. Precipitation can be snow, rain, hail, or sleet.
Answer:
The process of desertification presents a serious impact on the well-being and health of the people living
in the areas affected by droughts and land degradation
on an unprecedented global scale. The worst situations
can be found in Africa, which is threatened because the
land degradation processes affect about 46 percent of
the whole continent and create a health risk to people
living in the regions far beyond the affected areas.
Explanation:
Answer:
When the velocity of wind or water slows, eroded sediment is deposited in a new location. The sediment builds up in a process called sedimentation and creates fertile land. River deltas are made almost entirely of sediment that has eroded from the banks and bed of a river.
There are many landscape features specifically associated with rivers: V shaped Valleys - particularly in their upper parts, rivers often form V-shaped valleys whereas glaciers commonly form U-shaped valleys. The V-shaped valley is created by erosion. Meanders - the curves or bends of a river.
