<u>ANSWER:</u>
Hurricanes so frequent in areas close to the equator because "the ocean water can evaporate more quickly near equator".
<u>EXPLANATION:</u>
- Hurricanes are fast moving wind storms that use heat and most air as their fuel. The air near the 'equator' is warm and moist causing more hurricanes.
- The warm and moist air from the 'ocean surface' rises above and generates an "area of low pressure".
- This causes air from nearby areas to move to the area of low pressure. This new air becomes moist and warm. This warm air when cools forms clouds.
- This cloud systems and winds grows and spins fed by the "water evaporating" from the surface of the ocean. This in turn creates a storm called a hurricane.
Answer:
Seafloor spreading occurs along mid-ocean ridges large mountain ranges rising from the ocean floor.
Explanation:
The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.
The tundra is a biome on the Earth that covers approximately 20% of its land mass, and it is almost exclusively located in the Northern Hemisphere. It is an environment that helps in the regulation of the CO2 in the atmosphere, and it is one of the biggest natural CO2 sinks. The living organisms in the tundra, are using the CO2 for their needs, thus removing parts of it from the atmosphere, and when they die, because the tundra is cold, and the decomposition is very slow, most of the CO2 remains trapped, and doesn't go into the atmosphere.
Unfortunately, the global warming is slowly changing the tundra, and prolongs the summer periods, thus reducing the permafrost period of the year, so the decomposition of the living organisms is getting quicker, and also bigger percentage of the CO2 from them gets to the atmosphere.
