Why do polar regions have low temperature?

The polar regions are cold. Because of the chill polar air has a low capacity to evaporate water vapor in the air. … With less of this greenhouse gas in the air less longwave energy is absorbed in the lower troposphere. More longwave energy escapes to space thus helping to lower surface temperature on the whole.

Which of the following best explains the impact of climate change on polar regions quizlet?

Which of the following best explains the impact of climate change on polar regions? … Polar regions are warming more quickly than other regions because warming decreases the coverage of high-albedo ground cover like ice and snow.

Which statement about rain shadows is accurate?

What statement about rain shadows is accurate? In the western United States you would expect the rain shadow effect to produce heavier rainfall on the western-facing slopes of mountains than on the eastern-facing slopes. Which of the following terrestrial biomes are maintained by fires?

What are aquatic biomes categorized by?

How are aquatic biomes categorized? Why are they categorized differently than terrestrial biomes? They are categorized by salinity depth and water flow.

Which statement best explains why 50% of the atmosphere is below 5.5 km and 99% is below 32 km?

Which statement best explains why 50% of the atmosphere is below 5.5 km and 99% is below 32 km? The greenhouse effect is due to water vapor carbon dioxide and other trace gases in the atmosphere. Air is compressible.

What is the muddy bottom of a lake called?

Benthic Zone. the muddy bottom of a lake pond or ocean.

Why are the polar caps cold?

Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. The Sun is always low on the horizon even in the middle of summer. In winter the Sun is so far below the horizon that it doesn’t come up at all for months at a time.

Why are polar climates very cold quizlet?

Polar climates are also without sun for 6 months out of the year. This lack of sun makes polar climates very very cold. During the six-month that the sun is shining it hits polar climates at a very low angle so the Poles do not get much in the way of insulation. The snow reflects the sunlight back into space.

Why are the polar regions not becoming colder each year?

Although the polar regions radiate away more heat energy than they receive by insolation in the course of a year they are prevented from becoming progressively colder each year by: the circulation of heat by the atmosphere and the oceans.

How is the climate of polar regions different from tropical region?

Polar region remains very cold for most part of the year whereas tropical rainforest is hot and humid. Rainforests are located in the tropical climate region. … Polar climates are found across the continents that border the Arctic Ocean Greenland and Antarctica. Winters are entirely dark and bitterly cold.

Why are cold environments cold?

The main cause of cold environments is latitude. In the far northern and southern latitudes where temperatures are extremely cold permanent ice sheets exist and in Antarctica for example they cover much of the continent and are as thick as 2000m in many areas.

Which is colder Antarctica or the Arctic?

The main reason that Antarctica is colder than the Arctic is that Antarctica is a landmass surrounded by ocean and the Arctic is an ocean surrounded by landmasses. Antarctica also has a much higher average elevation than the Arctic and the Antarctic Ice Sheet is bigger and thicker than the ice in the Arctic.

Are polar regions warming faster or slower?

The Arctic is warming much faster than the rest of the planet and the loss of reflective ice contributes somewhere between 30-50% of Earth’s global heating.

Why are polar regions warming faster?

Ice is more reflective and less absorbent of sunlight than land or the surface of an ocean. When ice melts it typically reveals darker areas of land or sea and this results in increased sunlight absorption and associated warming. Polar amplification is much stronger in the Arctic than in Antarctica.

Which best explains why it rains in the deserts less than other areas on Earth?

Which best explains why it rains in the deserts less than other areas on Earth? Most deserts are bordered by oceans which draw the water away from the land because of gravity. Most deserts are bordered by mountains that prevent the flow of atmospheric water into the regions.

What is a biome climate?

A biome is a group of similar ecosystems that cover a broad area. Climate is the average weather in an area over a long period of time. Climate is the most important abiotic factor affecting the distribution of terrestrial biomes. … The moisture of a biome is determined by both precipitation and evaporation.

Which ecosystem experiences harsh conditions due to tides?

The intertidal zone is an ecosystem found on marine shorelines where a multitude of organisms living on the shore survive changes between high and low tides.

Who discovered biomes?

Frederick Clements
The term biome was born in 1916 in the opening address at the first meeting of the Ecological Society of America given by Frederick Clements (1916b). In 1917 an abstract of this talk was published in the Journal of Ecology. Here Clements introduced his ‘biome’ as a synonym to ‘biotic community’.Nov 27 2018

Why are aquatic systems not called biomes?

Aquatic systems are not called biomes The major differences between the various aquatic zones are due to salinity levels of dissolved nutrients water temperature depth of sunlight penet…

What biome is characterized by very low temperatures high winds and permafrost?

Which biome is characterized by very low temperatures little precipitation and permafrost? Tundra
Which two biomes have the least amount of precipitation? Desert and tundra
A biome is identified by its particular set of abiotic factors and its ___. characteristic plant and animal communities

What is the coldest layer of Earth’s atmosphere?

the mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface the mesosphere gets progressively colder with altitude. In fact the top of this layer is the coldest place found within the Earth system with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).Oct 2 2019

Can a lake disappear?

Scientists and explorers have discovered lakes rivers and other waterways around the world that seem to disappear entirely. In some cases sinkholes can cause entire lakes to disappear in a matter of days. In alpine areas and polar regions cracks in ice sheets can burst glacial dams draining lakes overnight.

Do all lakes lead to the ocean?

Because most of the world’s water is found in areas of highly effective rainfall most lakes are open lakes whose water eventually reaches the sea. For instance the Great Lakes’ water flows into the St. Lawrence River and eventually the Atlantic Ocean.

Can you dump sand in a lake?

Dumping sand along the shore of a lake can smother bottom-dwelling algae and invertebrates reduces the amount of available habitat and may cause a disruption in the food chain of higher organisms including fish. Deposited sand may also destroy spawning or nesting sites for fish.

Why is it colder up north?

Northern cities are colder than southern cities in the winter because in the winter the norther part of the northern hemisphere of the earth is farther away from the sun and the southern cities of the norther hemisphere. The reason for this difference in distance is that the earth is tilted.

What is the coldest place on Earth?

Oymyakon is the coldest permanently-inhabited place on Earth and is found in the Arctic Circle’s Northern Pole of Cold.

Why do Earth’s polar regions have cold dry climates because the sun’s rays?

It has a warm climate because it receives direct sunlight all year. The polar zones extend from about 66.5° to 90° north and 66.5° to 90° south latitudes. They have cold climates because the sun strikes the ground at a lower angle.
