Geography
1 answer:
mina [271]2 years ago
6 0

Answer:

<h3>Ocean salt primarily comes from rocks on land. ... Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.</h3>

34kurt

Answer:

Correct answer is A. The Middle East

Explanation:

There are 14 members of OPEC and most of them located in Middle East, including United Arab Emirates and Libya. Qatar was member until 2018.

None of the countries from Europe are members of this organization.

The same thing is with Central Asia, while from South Africa we only have Angola.

It is interesting that some of the largest petroleum exporting countries are not members of this organization.

9. Which forces do scientists believe are responsible for the movement of Earth's
SIZIF [17.4K]
The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.

Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.

Explain how the shading of the direct light of the sun causes a lunar eclipse.
creativ13 [48]
The lunar eclipse happens when the Moon goes through the Earth's shadow. Earth dependably has a shadow, which is made by the Sun. On those uncommon events when the Moon, Earth and the Sun are altogether arranged perfectly, the Moon goes through this shadow.This would happen each full moon if the Moon circled around the Earth in an indistinguishable plane from the Earth circles around the Sun.
