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:
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.

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.

The Earth is made up of five interdependent spheres: the geosphere (lithosphere), hydrosphere, biosphere, cryosphere, and atmosphere. The spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres. Changes that take place within an ecosystem are referred to as events. Events can occur naturally or they can be caused by humans. An event can cause changes to occur in one or more of the spheres or an event can be the effect of changes in one or more of Earth’s four spheres. This cause and effect relationship between an event and a sphere is called an interaction. Water in the lake seeps into the cliff walls behind the dam and becomes groundwater or evaporates into the air. Which spheres are interacting in this example?
A) hydrosphere only
B) hydrosphere and atmosphere
C) biosphere, hydrosphere, and cryosphere
D) hydrosphere, geosphere, and atmosphere

The total amount of sunlight that approaches Earth is about _______ in September as in March
half as much
twice as much
the same
Answers
Answer:
C). The same
Explanation:
As per the question, the aggregate sunlight received during the months of September and March is almost the same as both of these months witness an equinox marking the beginning of spring(in March) and the fall(in September). March 20 or 21 and September 22 or 23 are the two days when there is an intersection of the apparent path of the sun and the sun's center is right above the celestial equator. On these days, an equal amount of sunlight is received throughout the Earth(excluding the extreme poles) i.e. 12 hours of sunlight and darkness for 12 hours. Thus, option C is the correct answer.

What are the two major sects of Islam, and what is the main difference between them?
Answers
Answer:
Shias believe that Ali and his descendants are part of a divine order. Sunnis are opposed to political succession based on Mohammed's bloodline.
Explanation:
The two major sects of Islam are Sunni and Shia. The main difference between Sunni and Shia is their belief about who should have succeeded the Prophet Muhammad as leader of the Muslim community.
Sunnis believe that the Prophet Muhammad's successor should have been chosen by the community of Muslims. They believe that the first four caliphs, Abu Bakr, Umar, Uthman, and Ali, were the rightful successors of the Prophet Muhammad.
Shias believe that the Prophet Muhammad's successor should have been his cousin and son-in-law, Ali. They believe that Ali was the rightful heir to the Prophet Muhammad's authority and that the first three caliphs were illegitimate.
There are also some other differences between Sunni and Shia Islam, such as their beliefs about the role of the imam and the interpretation of the Quran.
However, the main difference between the two sects is their belief about who should have succeeded the Prophet Muhammad.
