Answer:
B. It can cause pollution of water in lakes and rivers
Explanation:
Poor use of fertilizers in Agriculture can affect the environment because they cause pollution of water in lakes and rivers.
Pollution is the introduction of filth or unwanted materials into the environment.
- When fertilizers are poorly applied on farms, they can cause pollution of nearby water bodies.
- Rain water usually during a down pour can wash them off into surrounding water bodies.
- They can also even infiltrate into the ground water systems.
- On getting into the rivers and lakes the alter the chemical balance and lead to severe pollution.
- One of such is eutrophication.
So, poorly applied fertilizers can cause pollution of water in lakes and rivers.
1. The answer is B. the asthenosphere
Asthenosphere is a layer of the Earth situated below the lithosphere. It is a semi-fluid and ductile rock or partly molten rock. Due to semi-fluid state of asthenospheric rock, it behave like a plastic and flow gradually. Thus, causes movement of continents.
2. The answer is C. collision between tectonic plates
The Earth’s crust becomes unstable when tectonic plates meet. As the plates slide past each other and push against each other. This causes earthquakes and volcanic eruptions at the edge between the plates.

Extrusive volcanic rocks are formed on the surface of the earth and cool relatively quickly from lava erupted from a volcano. The rapid cooling of lava on the surface does not allow for visible crystals to form. The crystals are minute and most can only be seen under a microscope. Basalt is an example of an extrusive igneous rock.
Intrusive igneous rocks are formed when magma cools within the crust. This magma cools slowly and so crystals develop in these rocks. Granite is an intrusive igneous rock.
