Upwelling
Explanation:
The rise of deeper water to the surface is called upwelling.
Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.
- This occurs usually along the short where wave action is very prevalent.
- Surface wave pushes away warm water.
- Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
- This nutrient rich water supports biological activities because they are rich.
- Wind along the coast can also force surface water down.

A Nitrogen got 7 electrons, which means every Nitrogen got 3 pairs of electrons and 1 single electron, ready to be shared.
A second nitrogen come with the same amount of electrons, 3 pairs and 1 single ready to shared.
The 2 nitrogens put in common their single electrons to create a pair.
Which means, that 1 pair of electron is shared between the nitrogens in a molecule of N2
Hope this Helps! :)
Answer:
The rock cycle
Explanation:
The three types of rocks are related and connected through the rock cycle. Rocks are not formed independently of one another, the process of their formation are interconnected.
Igneous rocks are made from cooling and solidification of magma. These magma are derived from the melting of rocks that have been subjected to high temperature and pressure.
When igneous rocks are formed, they can follow two path ways. They either get transformed to sedimentary rocks or metamorphic rocks.
When igneous rocks are subjected to metamorphic conditions, their mineralogy is altered to form metamorphic rocks.
If igneous rocks gets weathered and broken down by agents of denudation, they end up getting transformed into sedimentary rocks.
