Nitrogen and oxygen are the two primary gasses found in the earths atmosphere
<u>Answer:</u>
Scientists say global warming is largely due to a natural cycle it is evident from the fact that humans once settled in areas now covered by glaciers.
<u>Explanation</u>:
- It is seen on the geological timescale that the Earth has had five major ice ages that occurred as a result of tremendous changes in the climate from time to time.
- It is now believed that another ice age is due and the climate change that we are getting to experience is an indication that the ice age about to occur soon.
- Thus, a few scientists sat that global warming is largely due to a natural cycle.

The most densely populated European nation is the Vatican, located within Rome. It has 800 citizens with them living on a 0.17 miles squared, meaning there are 4,709 citizens per mile squared. This number might seem odd since it's much greater, but as Vatican is smaller than 1 mile, it cannot be compared without it becoming so big.
Answer:
The given statement about the air parcel is True
Explanation:
It can be explained as atmospheric pressure on air parcel is higher due to which it contracts when it is close to earth but if the temperature inside the parcel is more than that of the surrounding then due to low density it will rise upward and as the parcel gains height the air pressure exerted by the surrounding on the parcel reduces due to increase in height of the parcel from the earth and hence the air parcel expands. The entire process happens with heat being constant (adiabatic) i.e., amount of heat transferred in the expansion remains same.
Now, the same amount of heat is scattered on the expanded area leading the parcel to cool as it ascends.
