Answer:
Convection current
Explanation:
The seafloor spreading refers to the splitting of the oceanic crust in two opposite direction, resulting in the expansion of the ocean basin. And the continental drift refers to the large scale movement of the continents from one location to another, over the vast ocean water bodies.
Both these processes are believed to be caused by the convection current, that generates in the mantle portion of the earth. In the mantle, the magma being less dense, rises from the interior of the earth, and as it rises upwards, it forms convection cells, that forces the plates to move in different directions sharing a type of plate boundary. This entire process is known as the plate tectonic movement.
Answer:
AC. BD. 2 In the accompanying diagram of right triangle ABC, altitude BD is drawn to ... BD. AC. 3 In the diagram below, the length of the legs AC and. BC of right triangle ABC are 6 cm and 8 cm, ... BC. If BD = 2 and DC = 10, what is the length of AB? ... hypotenuse RS. If RV = 12 and RT = 18, what is the length of SV? 1) 6 5.
I believe the correct answer from the choices listed above is option A. A new energy source found in the ocean that is currently very costly to obtain would be methane hydrates. Although the high cost, it <span>represents a potentially vast </span>methane<span> resource for both the United States and the world. Hope this answers the question.</span>
EXTRUSIVE IGNEOUS ROCK
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust.
Answer:
Insolation is the amount of solar radiation that reaches the earth's surface through shortwaves. The earth also radiates heat energy like all other hot object. This is known as terrestrial radiation. The annual mean temperature on the surface of the earth is always constant.
Explanation:
The energy emitted by the sun is known as solar radiation. The incoming solar radiation to the earth is known as insolation. Radiation from the earth is called terrestrial radiation.
Answer:
Solar radiation is all the radiant energy emitted by the sun. Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation measured in space or at the Earth's surface. Isolation is the total solar radiation that reaches the earth's surface.
