Basalt is the rock that makes up a majority of the oceans floor!
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds.
Water pollution affects the entire biosphere – plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and population, but also to the natural biological communities.
The Grand Canyon is like a history book because you can see all the layers of rock and dirt throughout the ages, and scientists can read those to tell what happened.
Hope this helped :)
So, first of all let me explain the process of hydration to you.
The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products.
Considering this information, the answer is D.
The largest mountains on the continents are formed by stress deformation.
This is also know as strain, which is a process that occurs when the intensity of the stress is greater then the internal strength of the rock. This kind of activity, forming of mountains, occurs when to tectonic continental plates with same densities are colliding, so under the pressure, stress, they create, the area of collision is lifting up.
