Answer:
b. There is no definite top to the atmosphere. The pressure and density gradually get smaller as the altitude gets larger.
Explanation:
There is no specific top of the atmosphere. It varies from place to place. But generally it is considered to be 480 kilometers thick. But majority of its thickness is limited to 16 km only above earth surface. The pressure and density gradually get smaller as the altitude gets larger. The air pressure at sea level is 14.7 pounds per square inch and it decreases to 10 pounds per square inch at a height of 3 kilometers. From the above discussion we say that option B is correct
The mass of an object is the quantity of matter it possesses. The important thing to remember about mass is that it is constant, and therefore if you are on Earth, the Moon, Mars, or anywhere, your mass is always going to be the same.

Answer:
This is as a result of the movement of the current in the Southern Hemisphere and it is deflected in a counterclockwise direction by the subtropical gyre. Furthermore, the ocean current that is at the Southern Hemisphere is pushed by the Coriolis effect toward the left side because of the rotation of the Earth.

This is as a result of the movement of the current in the Southern Hemisphere and it is deflected in a counterclockwise direction by the subtropical gyre. Furthermore, the ocean current that is at the Southern Hemisphere is pushed by the Coriolis effect toward the left side because of the rotation of the Earth. Those are the major reasons.
