The Sahara desert is important for a multiple of reasons. One is that although it is a desert, there are many fertile areas of land making it great for farming and supporting life. It also acts as a natural barrier in between north and south Africa, which was able to impact trade with the South, slowing down innovation on both sides.
Answer:
Mesosphere lies in between 50 to 80 km above the earth surface and due to low density gases escape easily and hence it is colder.
Explanation:
Mesosphere has the capacity to not absorb the infrared radiation that's why the gases reflected from the earth surface escape the layer of mesopause and goes inside the thermosphere.
In the thermosphere, even the minute atoms of gases ca be absorbed by the layer which increases the air temperature and the air rises up hence making thermosphere as the hottest layer in the atmosphere.

Answer:
1. Compaction occurs where pressure is placed on loosely packed sediment. The volume of the sediment is reduced and water is squeezed out.
2. Cementation occurs when mineral-bearing water circulates among the grains, hardens, and cements the sediment grains together. This process is most effective when lithifying sand and gravel-sized sediments.
Explanation:
<u>Answer:</u>
There will be more stars than that we have counted last time.
<u>Explanation:</u>
- Considering our galaxy star is formed daily. Speed that the star formed is greater than the speed to count them by human.
- It is estimated that there are about
star in our galaxy.
- Even if we count the star to a specific place than will in big number, also there are about 400 million of star is born daily taking about the specific it will be smaller compared to the total but that will still be big number.
