Answer:
Explained below
Explanation:
In physics, we know that waves usually change direction when are refracted or when they penetrate layers with different densities.
Therefore, when a seismic wave penetrates penetrates the boundary of the earth's interior, part of it will be sent back and part will be transmitted into the medium as refraction occurs. When we record the reflected and refracted ray, it enables the calculation of the position of major boundaries in the Earth's interior. This also helps in providing information about the solid & liquid character as well physical properties of the various layers in the medium.
Carbon sinks <u>emit more</u> carbon than they take in is not <u>true</u>.
<h3>What are carbon sinks? </h3>
A carbon sink is said as a reservoir either <em>natural </em>or otherwise that has abundant storage of carbon-containing <u>chemical compounds</u>. This has been accumulated over an <u>indefinite time period</u> which results in lowering the concentration of carbon dioxide from the atmosphere.
Therefore, the most common carbon sinks are present in vegetation and the ocean.
