The answer is D. The Palaeozoic era was characterized by the supercontinent of Pannotia which was located at the current position where Chile is, 500 million years ago. There is evidence that shows that central Africa was once at the polar regions due to evidence of glaciers in its geological rocks. Due to tectonic movement, the Appalachians and the Ural Mountains were formed in the resulting Pangea supercontinent.

The best answer is reduction in acid rain.
Acid rain is rainfall which has been rendered acidic by pollutants in the atmosphere. This kind of rain is typically harmful to forests and lakes.
The main cause of acid rain is human activities. The burning of fossil fuels such coal in electrical generating plants and crude oil products such as gasoline and diesel in car engine releases sulphur dioxide and nitrogen oxide into the atmosphere.
These compounds mix with water very high up in the atmosphere and form acid pollutants which fall on the ground as acid rain.
Use of clean energy will eliminate burning of fossil fuels and thus no acid rain will be produced.
Answer:
We study about the sun because
The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.
Explanation:
How does the Sun help to protect life on Earth?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
