Answer:
D. Salt Weathering
Explanation:
Salt weathering is defined as a geomorphic process resulting in the physical disintegration of rocks or stones and in the fretting of their surfaces. Often you tend to find the best examples of salt weathering in dessert areas and coastal areas. You can find three distinct types of weathering which are biological weathering, physical weathering, and chemical weathering.

Answer:All planets move in elliptical orbits, with the sun at one focus. This is one of Kepler's laws. The elliptical shape of the orbit is a result of the inverse square force of gravity. The eccentricity of the ellipse is greatly exaggerated here.
so it is true
Explanation:
To be able to identify that the object is in the same motion, we should find the graphs that has an increasing slope of displacement and with the constant velocity with varying time. Graphs on letter D satisfies these requirements.
<em>ANSWER: D</em>
Explanation :
The phenomena in which the ray of light bend towards or away from the normal is called the refraction of light. Light always travels in straight line. If the speed of light in both medium differs then refraction occurs.
According to Snell's law :
Where 
and 
is the refractive indices of two medium 1 and medium 2.
and 
is the speed of light in medium 1 and medium 2.
Hence, the given figure shows the refraction of light.
