The crescent moon appears when the moon is less than half illuminated and takes on a curved shape in the sky. It is visible after sunset and before sunrise, around the time of the new moon phase. The shape of the crescent moon changes as it moves in its orbit around the Earth.
The light from the Sun can only light up half of the Earth at a time, because it is a sphere. When one part of the Earth is facing away from the Sun, there is nothing besides the Moon and the planets to reflect sunlight back at the night side. Just after sunset and just before dawn, some of the sunlight scatters through the upper atmosphere to provide some illumination.
In a typical sunset, the colors appear in the following order: first, you may see shades of yellow and orange as the sun begins to set. As the sun moves further below the horizon, red and pink hues become more prominent. Finally, as twilight sets in, you may notice purples and blues in the sky. This sequence is due to the scattering of sunlight by the Earth's atmosphere, with shorter wavelengths (blues and violets) being scattered more than longer wavelengths (reds and oranges).
The waxing crescent phase lasts for about 7 days, occurring after the new moon and before the first quarter moon. During this time, the illuminated portion of the moon gradually increases as it moves in its orbit around the Earth. The crescent shape is visible shortly after sunset, becoming more pronounced each evening.
A sunset typically consists of three main phases: the first phase is when the sun starts to descend towards the horizon, creating vibrant colors in the sky. The second phase is when the sun dips below the horizon, causing the sky to turn shades of red, orange, and pink. The final phase is when the sky gradually darkens as night falls.

The deep cracks which occur on the upper surface of glacier when it negotiates a bend and detaches from the rockwall behind and moves downslope.
As the air mass moves upslope, it cools adiabatically and its moisture condenses, leading to cloud formation and precipitation. On the downslope side, the air warms adiabatically and its moisture content decreases. Overall, the upslope side tends to be cooler and wetter, while the downslope side tends to be warmer and drier.
Gravity is the force that moves sediment in a mass movement downhill. The force of gravity acts on the weight of the sediment, causing it to slide, flow, or fall downslope.
When a mass of material moves downslope along a curved surface, the process is called slumping. This can occur when the stability of the material is disrupted, causing it to slide or slump downwards due to gravity.
erosionMass wasting-also called mass movement-is a collective term and covers many different phenomena. Overall, it refers to the usually slow (but sometimes rapid) downslope movement of rock, soil, regolith, and sundry debris under the influence of gravity.Read more: what-is-mass-wasting
