Make sure you numbers with variable are on one side and the numbers
Answer:
C. anything that has mass and takes up space
The answer is D. Stars are formed from interstellar clouds because of the Law of Universal Gravitation. The interstellar clouds are termed as nebula. When other stars dies a supernova occurs then the gravity from this pushes matter into the clouds until it cannot overcome the gravitational pull and it collapses which heats matter up forming a star.
A weather front or front is a
narrow region between two air masses of different densities. Because of the
difference in density between warm and cold front, cold air tends to go
underneath the warmer air. It often creates the strongest winds above the
ground surface. This is caused due to the heat and mass transfer between
particles of air. They can be slowed down by the presence of mountains and
valleys. Cold air moves fast and the temperature around it can be felt as if
you are blown away due to its density. Whereas warm air moves slowly.
Answer:
more dense;change to a liquid to a solid
Explanation:
At high pressure , the gases volume is reduced ,resulting in an increased density.
