Heath and pressure manage to move the material between the bottom and top part of the mantle, causing currents, and affecting the surface of Earth.
Explanation:
The heat and the pressure are crucial for the cycling of matter on our planet. This process happens in the mantle layer. The lower part of the mantle is hotter because of the higher influence by the core, while the upper part is not as hot (though very hot for surface standards). This causes the material in the upper part to be more solid and denser, which in turn causes it to sink toward the bottom. As this material sinks the hotter and less dense one from the bottom is pushed upward. This creates the convection currents.
As the material from the bottom moves upward it comes in contact with the lithosphere. It puts a lot of pressure on it and supported by the heat manages to crack it, which created the tectonic plates. Because of the constant pressure the tectonic plates are pushed and moved on the surface of Earth. On some places (subduction zones) the crust from the surface sinks into the mantle, while from the mantle we have rise of magma toward the surface, so the material is constantly circling and being recycled.

Explanation:
There is no explanation. there minerals underground or below sea. Sometimes above ground. They are just created for things.
Yes I do think because we’ve added tar and many other things to our roads the level of it is lower. The reason being of fog does have something to do with the clouds and the pressure that is being lowered to create the fog.
The answer is a) True
Since Independence, almost every African country has been plagued by the cycle of Poverty.
Poverty has led to the development of a culture of bribery and kickbacks in between almost every aspect of the government.
With little investment in education and health, the average person has suffered even more.
Many African countries have taken on billions of dollars of debt that they can never pay off.
This has resulted in a 'debt trap' where the little money a country is able to generate, has to be paid in the forms of loans.
Lack of government funds, poor infrastructure, low education, high corruption has also resulted in numerous local rebels and quasi-militia factions mushrooming to challenge what they see as failed governments.
When you combine all these factors, you can see how poverty has resulted in a Pandora's box of problems for African countries.
