Gravity plays an important role in the separation of liquids because it determines the volume of liquids, and therefore, it affects the density.
When you mix different liquids they often separate forming defined layers. This process is possible due to the differences in density (mass/ volume). In this way, the liquid with a lower density will float over the liquid with a higher density.
This phenomenon is affected by gravity or the force that makes everything on the Earth to be pulled towards the center of it. This is because gravity exerts pressure over bodies and affects the volume, which is one of the factors that determines density.

Answer:
b) Magma B
Explanation:
The magma that forms a basalt plateau or a shield volcano is a mafic (basaltic) magma. This magma is low in viscosity, making it very liquid, so when there's an eruption there's lava flows coming down the slopes like rivers, moving relatively fast. This type of magma has low content of silica, which is the reason why it is low in viscosity. The low viscosity also contributes to very small amount of gases in the magma, as the gases can escape from it very easily so they do not come in a situation to be trapped. The low amount of gases means that the volcanoes with this type of magma have calm eruptions, and explosive eruptions are either nonexistent, or extremely rare.
It is false that the mathematical system in Mesopotamia was based on the number 7. O.
<u>Explanation:</u>
The mathematical system is Mesopotamia was based on the number 60 at it's base and not on 7. This numeral system is known as sexagesimal which had 60 at it's base.
This originated in the 3rd millennium BC and passed on to the ancient Babylonians and it is still used for measuring angles, times, geographic co ordinates. Since the statement that the mathematical system in Mesopotamia was based on number 7 is incorrect.
Because the rock making up continental plates is generally lighter and less dense than oceanic rock, it is too light to get pulled under the earth and turned into magma. Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.
<span>At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
