Asthenosphere best describes the hot, weak, inner part of the upper mantle, which can flow. Correct answer:A
The asthenosphere is part of Earth's mantle that is located below the lithosphere.It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid.
Answer:
$160
Explanation:
Given
Total budget = $400
Percentage amount he can spend on clothing = 40%
Amount he can spend on clothing = 40% of $400
Amount he can spend on clothing = 0.4×400
Amount he can spend on clothing = $160
Hence the amount he can spend on clothing is $160
Answer: d. all of the above
Woodlands and forests are essential sources of food and shelter of both human and animals. With wildfire and forest destruction, such sources and even the very existence of varying species are significantly affected and devastated.
Answer: The statement above violate this particular principle of active listening, which is:
c. Avoid trying to solve problems .
Explanation: When the listener is trying to make an excuse, and a call comes in, to effectively carry out that excuse. Then he avoids trying to solve the problem.
The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]
Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]
Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.
