The Climate is hot, Wet and humid in Malaysia and cold and wet in siberia throughout the year. Why?​

Answers

Answer:

This all has to do with the location of the two areas.

Explanation:

Siberia is farther away from the equator, therefore, the sun does not make direct contact with it. The equator is the middle of the earth, and because it gets more exposure to sunlight, and the sun is always directly above them in the sky, the climate is very different from areas in places like Russia, Canada, and Iceland.

It has everything to do with where the two places are located.

Because Siberia lies further distant from the equator, the sun does not shine directly on it.

The equator is the geographic center of the planet, and since it receives more sunshine and the sun is constantly directly above them in the sky, the temperature is considerably different from that of Russia, America, and Iceland.

How is water pollution a huge concern and problem for us and our environment? What are some actions we could do to help solve this problem?

Answers

Answer:

As you know, water pollution partakes a major part and length into our environment by the use of diesel machinery and basically any production plant.

When you want to help reduce this problem or make a change you likely would want to go on social media and conduct some research on what you can do. Some prime examples for yourself would be to quit driving diesel vehicles and maybe tell your friends to quit it as well. You may want to also tell them to not throw out their trash because that ends up in the water.

Overall theres a complete cycle to this of smoke polluting our clouds that release acid rain to ruin and destroy our environment, thank you.
