They form in the ocean where undersea volcanoes are errupting. The magma turning into lava piles up on top of itself over lots of time to form land.
Clothing in Africa is worn long and loose because it is too hot to wear tight clothing, but they still need coverage to protect themselves from bugs.
Answer: B.
Air pressure decreases as you increase in altitude.
Explanation:
Gravity pulls the gas molecules towards the center of the earth. This pull of gravity becomes stronger and closer to the center at sea level. Air becomes dense at sea level where the gravitational pull is stronger. Gases at the sea level are also compressed by the weight of the atmosphere above them. The force of the earth weighing down over a unit air is known as atmospheric pressure. At higher altitudes, the atmospheric pressure is lower and the air is less dense than at higher altitude.
