Answer:
A. Deposition - sediment is set down in a new place
Answer:
Position 2
Explanation:
Since it is on the Tropic of Capricorn, for it to be exactly on top of Africa, it must be in position 2. The Tropic of Capricorn is special because the sun is directly on top of it when the south part of the Earth is facing the sun, like position 2. Position 1 and 3 are directly at the Equator because neither part is tilted towards or away from the sun. Position 4 is directly above Tropic of Cancer. The Tropic of Cancer, like the Tropic of Capricorn, has the sun directly on top of it when the north part of the Earth is tilted towards the Sun.
I hope this helps!!! :)
Melanophores are small pigments that are present in the dermis layer of the skin of a shark. They impart a gray color to the dorsal and lateral surface area of the shark. They help in background adaptation and countershading of the body, which makes a shark difficult to be seen.
A decrease in the size of the substance when cooling is the Thermal Contraction.
<u>Explanation:</u>
The contraction or the shrinkage of any substance when they cool is called as "Thermal Contraction". The properties of any substance changes physically when there is a change in the temperature. There occurs some expansion or contraction of substances when they are exposed to the changes in the temperature.
All substance will tend to expand when they are heated and they will shrink or contract when they are cooled. This occurs due to the fact that when the temperature changes, the energy levels of these substances also changes. Thus when we cool any substance, then it will lose heat energy as a result of which the atoms that are present in that substance will move slow and closely.
