The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.
Heat as hot air rises thus causing a disruption in the flow of air
In 2021 the population count was 7.9 Billion people.
Answer:
new volcanoes
Explanation:
The mid-ocean ridges occur at places where there is a divergent plate boundary between two plates, and the boundary is located on the ocean floor. At this type of boundaries, the tectonic plates are moving away from each other, and there is constant volcanic activity between them.
The volcanic activity produces lot of magma, which quickly cools off in the water and piles up, creating underwater mountain ranges known as mid-ocean ridges. This constant piling of igneous rocks from the rising magma, produces new crust, or rather creates new ocean floor.
The old ocean floor is pushed aside, and there is a general principle that the crust at the mid-ocean ridge is the youngest, and the further away a place it is from it, the older the crust is.
Along all of the mid-ocean ridge there is constant volcanic activity, and that volcanic activity creates lot of new volcanoes on the ocean floor.
These are all true statements. When the igneous rocks are deep in the ground they crystallize slowly. The bigger the temperature and pressure, the slower the process. This type of igneous rocks are called intrusive rocks. Because of the slow cooling and higher temperatures and pressure, the crystals are big and very well shaped, and by their size and structure you can easily tell at what depth and in what conditions the rock has formed.
