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.
Answer:
lots of bodies of water, lots of mountains
Explanation:
What, is being called the midpoint exactly? My guess would be that Point C is the midpoint because it is the middle point of a line segment.
Answer:
B. located further south during winter because cold air covers a larger area of the northern hemisphere during winter
Explanation:
- As in winter, the polar get stream becomes strong when it moves to the south as the northern hemisphere gets colder and thus the contrast in the temperature makes the polar jet streams to move south. As they are produced by the factors of the solar radiation and the pressure cell formation and thus moves in the action of the Coriolis force.
B. the most dangerous job in the United States.
Mining is considered one of the most dangerous jobs in the World and 50-60 mining workers die in the United States every year. They are in danger from workplace accidents such as explosions, cave-ins and chemical leakages. Therefore it makes sense that this would be the answer.
