Why do vast amounts of sea ice exist in polar oceans?

Why do vast amounts of sea ice exist in polar oceans?

When strong winds in the Arctic and Antarctic regions force icebergs and sea ice away from the coasts and out to sea, areas of open water remain where air and water are in direct contact with each other. These areas are called coastal polynyas, and they are the places where sea ice is created.

What is the average surface temperature of the ocean?

28-86o F

What is tropical water temperature?

The water temperature of tropical oceans thus typically exceeds 20°C (68°F) and stays relatively constant throughout the year. Particularly intense radiation directly over the equator evaporates seawater and forms a mass of very warm, humid tropical air that subsequently rises and cools as it flows north and south.

What are the 3 main temperature layers in the ocean?

What are the three general layers of ocean water?

The ocean has three primary layers. 2. The layers are the surface layer (sometimes referred to as the mixed layer), the thermocline and the deep ocean. 3.

Why was the sea level lower 15000 years ago?

The main reasons for sea level fluctuations in the last 15 million years are the Antarctic ice sheet and Antarctic post-glacial rebound during warm periods. The current sea level is about 130 metres higher than the historical minimum.

What two major plates affect Mediterranean?

The tectonic framework of the eastern Mediterranean and Middle East region is dominated by the collision of the Arabian and African plates with Eurasia (e.g., McKenzie, 1970; Jackson and McKenzie, 1988).

How quickly are the plates moving at the Mediterranean Sea?

For millions of years the African plate, which contains part of the Mediterranean seabed, has been moving northward toward the Eurasian Plate at a rate of about an inch every 2.5 years (a centimeter a year).

Is the Black Sea deeper than the Mediterranean?

Currently, the Black Sea water level is relatively high; thus, water is being exchanged with the Mediterranean. The Turkish Straits connect the Black Sea with the Aegean Sea and comprise the Bosporus, the Sea of Marmara, and the Dardanelles….
