Get more great content like this delivered right to you! The best explanation for the lower humidity is that, Warm air rises at the equator, cools, and sinks at 30* latitude, Open oceans produce the largest share of Earth's biomass because the net primary productivity (NPP) of the oceans is, Low, but the large expanse of the oceans supports enormous numbers of producers such as phytoplankton, Surface oceanic circulation results most directly in the, Distribution of heat from tropical to temperate and polar regions. Large masses of water that move together, called ocean currents, transport heat, marine organisms, nutrients, dissolved gasses such as carbon dioxide and oxygen, and pollutants all over the world. On average, the temperate deciduous forest remains above freezing throughout the year The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area. October 20, 2021. c. carry diseases that infect native species The study suggests climate change will continue to speed up across ocean currents, potentially limiting the heat the ocean can capture and complicating migrations for already stressed marine life. d. The rate at which the resource was being recycled. surface oceanic circulation results most directly in the. Viewed from above, currents in these subtropical gyres flow in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere. d. carnivore Air is a relatively poor thermal conductor (which means it is a good insulator), so conduction represents only a small part of the energy transfer between the Earth and the atmosphere; equal to about 7% of the incoming solar energy.

This causes surface waters to grow more buoyantand more reluctant to mix with waters below. Which of the choices below are NOT true? Most abundant element in Earth's atmosphere, Country with largest area of boreal forest, Country with largest are of land affected by desertification, Country with largest area of temperate deciduous forest, Traveling southward from the Arctic region of Canada to the tropics of Panama, one passes through several biomes - tundra, coniferous forest, temperate deciduous forest, and tropical rain forest. Surface currents, also called horizontal currents, are primarily the result of wind pushing on the surface of the water, and the direction and extent of their movement is determined by the distribution of continents.

Carbon dioxide This is an example of what type of plate boundary? Two years ago, oceanographers made a surprising discovery: Not only have oceans been warming because of human-driven climate change, but the currents that flow through them have acceleratedby some 15% per decade from 1990 to 2013. The environmental impact of a population on a given area depends on, Surface oceanic circulation results most directly in the. Differences in temperature and salt content of the water cause some areas of water to sink and some areas of water to rise.
