Answer: The correct options are:
<em>exerts more pressure as it increases
</em>
<em>measures how tightly molecules are packed
</em>
<em>equals mass divided by volume</em>
Explanation:
Air density can be described as mass per unit of volume of the volume of air.
As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
Only the federal government regulates interstate trade
Option D.
<u>Explanation:</u>
The federal government is the central government in the United States of America which is linked with the welfare of the whole country and the state government is linked with the welfare of the people of a particular state only in the country.
Because of the difference in the aims of the two types of the country, the delegation of powers is also different between these types of the government. one of the powers which rests with the central but not with the state government s the regulation of the inter state trade.
The blank spaces in the task statement should be filled with; greater; slower respect.
<h3>Severity of storm activity along warm and cold fronts</h3>
Warm fronts conventionally often bring stormy weather as the warm air mass at the surface rises above the cool air mass, with the formation of clouds and storms.
Warm fronts move slower than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers (1,400 mi) over an area of approximately 344,400 square kilometers (133,000 sq mi).
<h3>
What are coral reefs?</h3>
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny living animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups.
<h3>
Coral Reefs of India:</h3>
India has four coral reef areas: the Gulf of Mannar, Andaman and Nicobar Islands, Lakshadweep Islands, and the Gulf of Kutch. Coral reefs protect humanity from natural calamities. They provide revenue and employment through tourism and recreation.
<h3>
Coral Reefs of Australia:</h3>
The reef is located in the Coral Sea, off the coast of Queensland, Australia, and is separated from the shore by a strait that is up to 100 miles wide and 200 feet deep in places. The Great Barrier Reef is the world's largest single structure built by living beings, visible from space.
