Answer:
A.) A warm ocean current flows along the coast
Explanation:
The sea ports which remain ice-free are called "warm-water ports." Other than those that can be found in Europe, warm-water ports can also be found in <em>New York</em> and <em>Canada.</em> This is due to the<u> warm ocean current that flows along the coast in these areas</u>. This allows the area to be free from ice, thus ships can just come and go. It is said that the "Gulf Stream" is responsible for bringing the warm water to Europe. However, other countries have cold-water ports just like in Russia.
The human activity in China's climate has had huge impact for the past few decades in particular. We can see it in two ways:
1. Negative effects; these are consisted in changing the climate on local level, but the problem is that those local changes are on lots of places. China has huge cities, the industry is the biggest in the world and not very caring about the environment, so the cities and their close surroundings have their own unique micro climate mainly because of the enormous pollution that changes the air structure and because of the overheating of all the infrastructure in the cities, as well as stopping the natural wind flows.
2. Positive effects; these can be seen in the Inner Mongolia province in China that is mainly desertous region. The scientists and the local population with mutual collaboration in the past few years are turning the desert into a green territory by using plants that are evergreen but also have no problems with extreme droughts and lack of water.
Answer:
A. The Mysterious dark matter is the fastest-moving material in the universe
Explanation:
Everything in the Universe is in motion because forces exist in the Universe. The gravitational force and the electromagnetic force ensure large objects are in motion while the weak and strong nuclear forces ensure the quantum world is constantly in motion. If there were no forces, there would be no motion.
This motion is the most obscure as it is not physical motion as such, but rather a change in the very nature of the universe. The primary source of verification of this expansion was provided by Edwin Hubble who demonstrated that all galaxies and distant astronomical objects were moving away from Earth, known as Hubble's law, predicted by a universal expansion.
