<span>When atoms react they form a chemical bond which is defined as a force of attraction that holds atom together. A force of attraction is defined as a kind of force that draws two or more objects together regardless of distance. There are two major categories of forces of attraction, one is intramolecular and intermolecular. Intramolecular forces is the presence of forces in atoms internally. While intermolecular is the force by which the force that is existent in two or more elements. </span>
Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces. ... Any shoreline is a wind machine, because of solar heating effects.
A. Absorption
-It's the process in which any objects can be absorbed, thus in this case, sound waves.
I'm not completely sure if this is correct, but the other three choices don't make sense too much, then again this is on the subject of biology.
-Diffraction involves light and distance, not sound
-Reflection has to do with the many subjects which reflect, this can't relate to sound
-and transmission involves the transmitting or movement of a certain object to another, in biology's case, cells or pathogens.
That's why I believe it's A.
The Moho beneath the Tibetan Plateau is significantly deeper than that beneath the neighboring Yangtze Craton and Indochina block.
Sudden Moho fluctuations are also observed over the southeastern plateau boundary, much like those under the eastern plateau margin. Interpret the severe Moho fluctuations over the plateau boundary as having formed during the late Miocene Tibetan Plateau extrusion southeastward. The steep Moho slope was preserved, although subsequent gravity collapse brought crustal extension and mild topographic variation.
The surrounding geosciences are particularly interested in the tectonic uplift of the Tibetan Plateau. A common paradigm for interpreting the geodynamic mechanism on the Tibetan Plateau's edge is mid-lower crustal flow. Due to the varied strengths of ding blocks, the model predicts different surface and Moho topographies across the plateau boundary, i.e., abrupt boundaries on the eastern plateau boundary and mild fluctuations in the southeastern plateau boundary.
