Explanation:
Most important for understanding atmospheric pressure is knowledge of the variations it is subjected to under the influence of various factors.
When we have an atmospheric pressure higher than 1013 Mb or hPa (high pressure or anticyclone) it is why the air is heavier, coming down colder and drier and gives us a good clue to say we can have a good time and / or cold.
The centers of high atmospheric pressure generate divergent air movement out of the center and also subsident (top to bottom) causing the air to become drier. High pressure plays the opposite role of low pressure: it dries the air, decreases cloudiness and conditions for rain.

very tall mountain ranges
Answer: very tall mountain ranges
Explanation:When there is a collision between two continental plates, they become crunched up and then the rock folds at the boundary where it becomes lifted up and this leads to the formation of mountains and mountain ranges.
When collision occurs between two continental plates, both plates cannot be subducted because of their increased bouyancy. So when this collision occurs, features like subduction zone, trench and wedge do not occur. This type of collision occurs when the sea becomes narrower until both plates collide.
After the occurence of the collision, oceanic lithosphere breaks off and then sinks down into the mantle. The subduction zone then becomes inactive.
The two continents now welds together as they are being compressed together as time goes on.
The earth crust then becomes thickened by the under- thrusting of one continent under the other continent.
An example of this collision is the Himalayas where India collided with Asia.
