The correct answer is A. Intrusive is due to magma cooling deep within Earth's surface and extrusive is due to it cooling at Earth's surface.
The intrusive rocks are forming deep bellow the surface, and they cool off very slowly. Because of that they are forming big crystals.
The extrusive rocks are forming on the surface, and they cool off very quickly. Because of that they are forming small crystals.
Answer: Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases. Toxic chemicals that accumulate in top predators can make some species unsafe to eat. Pollution can also damage crops and trees in a variety of ways. Ground level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather)
