The government has to release mercury into the environment because we can not get rid of mercury. It is released from the burning of fossil fuels, from various natural resources and industrial activities. And, it can not be left at the place of emission because it is very harmful and accumulates in the organisms. Therefore, regulations are made to control the amount and the place of release of mercury.
Igneous rocks are defined as formations made from solidified lava or magma.
When lava or hot Magma reaches the surface of the earth or a water body it quickly cools down and changes it's from from a hot liquid to a solid rock.
The chemical composition of Igenous rocks can vary depending on their location, cooling time etc.
However, most Igenous rocks contain some or all of the following minerals:
1. Quartz
2. Micas
3. Amphiboles
4. Olivines
5. Pyroxenes
6. Feldspathoids
7. Feldspars
Answer:
Tectonic plates collide.
Explanation:
Convergent boundaries are the meeting points of two tectonic plates that involve the collision of one plate with the other. Convergent boundaries can be subduction boundaries when there are two oceanic plates or an oceanic and a continental plate that are colliding.
Another type of convergent boundary is formed when two continental plates collide. When this happens, both of the plates buckle and fold to form high mountains since two continental crust plates cannot engage in subduction.
I would say A, C and D from my point of view because you would learn new things about the culture from observing, asking questions and being open to try new things.
