Answer:
Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.
Explanation:
The unsaturated zone is the area of the subsurface that is above the groundwater table. The pores of the soil and rock in this zone contain both air and water.
<h3>What is the water table?</h3>
The water table is the subsurface border between the unsaturated and saturated zones.
The water table is an underground border that separates the soil surface from the area where groundwater saturates crevices between sediments and rock fissures.
At this point, the pressures of water and air are equal.
The unsaturated zone is the soil surface above the water table, where both oxygen and water fill the crevices between particles.
Therefore Option C is correct as it is where a person will immediately reach after drilling a well through an unsaturated zone.

The element with the greatest number of valence electrons available for bonding is chlorine. Among all the choices, chlorine is the element that belongs to the higher group number, group 7. Selenium is from group 6. Boron is from group 5, while calcium is from 2. Since the group number also equates to the number of valence electrons, chlorine is the answer.
There are lot of factors that contribute to migration of the people. They are roughly divided into push factors and pull factors.
The push factors are the factors that are making the people leave a place. These factors are numerous, and some of the most important are of political nature.
As political push factors can be seen:
- state persecution; the people are forced to migrate because the government is forcing them to do so.
- war; the people migrate because of safety reasons, as in war there is high chances that they will lose their lives, or be forced to participate in the war without them wanting to.
- lack of political liberties; the world has become more and more democratic, so the people naturally want to have rights. In some countries this is not the case, and the people are restricted in their liberties, so in order to be able to express their opinion they migrate.
- large scale corruption; it forces the people to migrate because the systems are not working properly. Only small fraction of the population is able to thrive in this kind of circumstances, while the majority suffers.
- cultural political; the migrate because of internal problem based on cultural diversity and tensions or conflicts between different groups.
