How do back-arc basins form? View Available Hint(s) How do back-arc basins form? Tensional stresses resulting from slab suction stretch this part of the crust, causing it to thin vertically. Compressional forces bend the sedimentary layers in the back-arc region downward, creating a bowl-like depression. Compressional forces make the back-arc region thicker and denser than the volcanic arc. This higher density causes the back-arc region to sink into a basin shape. The back-arc region subsides into a downwarped basin shape from the added weight of addition of sediment from mass wasting events. A mountain range also forms on the side of the back-arc basin opposite of the volcanic arc, creating a lowland in between the two ranges.

Answers

Answer 1

Answer:

Compressional forces bend the sedimentary layers in the back-arc region downward, creating a bowl-like depression.

Explanation:

The back-arc basin is formed with the weight of one tectonic plate on top of another. This happens when a tectonic plate with a higher density protrudes over a tectonic plate of lower density causing a "sinking" of the less dense plate. This causes a spread of the posterior arch that folds to form a trench-shaped depression. This "sinking" is called subduction and allows the upper tectonic plate to defeat the mantle on the overlapping plate, causing a greater chance of magma leaking onto the surface.

What is a “jet stream"? What type of air does this one separate

Answers

Answer:

A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — 250 miles per hour or faster.

Explanation:

Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

When a plane lands at the local airport, it touches ground and creates an angle between the ground and the belly of the plane. What is a good estimate of the angle measurement?

Answers

Answer:

Approximately 3 degrees

Explanation:

As well as taking off, the landing of the plane must be monitored very well, allowing the entire trip to be made safely and efficiently. At landing, it is important for the pilot to estimate which is the best descent profile and what is the best angle to be established between the ground and the belly of the plane. It is preferable that this angle is approximately 3 degrees, which promotes a safe landing, but this value can have small variations.
