Answer:

B) The surface layer of permafrost thaws in summer.

Explanation:

Permafrost is frozen ground or frozen soil. It is a landform in which the ground  remains frozen for over a long period of time usually more than two years. Permafrosts are usually found in high latitude regions. For a permafrost to form, the temperature must remain considerably below freezing point.

The surface layer of a permafrost is bounded by the permafrost table and below it lies the active layer. During summer when temperature rises above freezing point, this layer thaws. In winter times, the surface layer remains frozen.

What latitudes experience the<br> coolest temperatures?
Elanso [62]

Answer:

you should expect, on an annual basis the high latitudes (60 to 90 degrees N/S) are the coldest.

Explanation:

Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.

The Earth’s axis is tilted 23.5° to the perpendicular, meaning that the amount of sunlight that a particular latitude receives changes with the seasons. From April to September, the Northern Hemisphere is tilted toward the Sun, where it receives more energy; the Southern Hemisphere receives this additional energy between October and March, when it is tilted toward the Sun.

Although there is no specific ‘type’ of climate, there are three general climate zones: arctic, temperate, and tropic.

Arctic

From 66.5N to the North Pole is the Arctic; from 66.5S to the South Pole is the Antarctic. Places within the arctic climate zones tend to be snow- or ice-covered year-round. This is despite the fact that they tend also to be exceptionally dry, sometimes receiving as little precipitation as the world’s driest deserts. Very little snow falls on these high-latitude regions, but even less melts due to the cold temperatures and scarce sunlight. The deep ice and snow that covers these regions has been built up over hundreds, indeed thousands, of years. In these regions, the Sun hovers above the horizon at midnight in the summer and never rises at all at times during the winter.

Temperate

The temperate zone is located between the arctic and tropic zones. However, ‘temperate climate’ is something of a misnomer since most regions located within the temperate climate zones experience distinct changes across four seasons. For example, in much of eastern North America – from the Ohio Valley in the United States to the southern shores of Hudson Bay in Canada – the ‘temperate’ climate can experience both arctic and tropical weather in the same year. These climate variations increase the further an area is from an ocean or another large body of water; they diminish in areas where oceans and other large bodies of water are able to influence the climate more strongly. Temperate regions are also affected by the direction of the air flow they receive. Areas in Canada, for example, have cool Arctic air passing through, while the southern United States receives warm air from the Gulf Stream.

Tropic

The tropical belt of land and sea extending around the globe on both sides of the equator – between 23.5S and 23.5N – receives the most sunlight, but it is not necessarily the hottest since it is covered extensively by oceans that use some solar energy for evaporation. This combination of high moisture and intensive solar heating results in a persistent zone of convection (the upward movement of moist, unstable air) known as a tropical low, which often results in generous cloud formation and frequent rainfall. These factors also help moderate the temperatures within this zone.

Most areas, however, are characterized by distinct sub-climates where average temperatures, precipitation, and other factors vary noticeably. Although there are different classifications of world climates, many of these sub-climates include low latitude tropical rainforest and tropical savanna; middle latitude maritime, mediterranean, and steppe; high latitude subarctic, tundra, and polar ice cap; as well as desert and highland areas.

sergeinik [125]
A succession of ocean waves set in motion by a submarine earthquake (also known as underwater earthquake) is called a tsunami. This happens when tectonic plates move, converge, or subduct. Submarine earthquakes are common in Asia where there’s a submarine earthquake zone called Pacific Ring of Fire.

dlinn [17]

Answer:

C. Alabama has six major manufacturing centers

Alabama is not a landlocked state, because it shares it's border with the Gulf of Mexico. Alabama's state capital is in Montgomery, not Tuscaloosa. Most of the population sits on the North half of the state. So the answer would be C. You can count the factories on the map too. Hope this helps friend.
