The Earth's mantle is the layer of rock just below the Earth's crust. Just under the crust, it is solid. It is very hot, and the other part of the mantle is soft, kind of like melted candy.
The Earth's mantle is rock-hard but it actually flows around the outer core, moving about as slowly as your fingernails grow. The mantle tends to be 2,900 kilometers thick, and makes up 84% of Earth's total volume.

In natural environments, horses typically live in relatively stable social units. Horses live in herds so that they are able to fulfil their basic needs, which are to avoid danger or harm, and to reproduce successfully and bring up healthy foals.
Homeostasis is the maintenance of internal conditions within a body. Examples of homeostasis in human includes the regulation of blood glucose level, the regulation of body temperature, or the regulation of water volume inside body.
For maintaining blood glucose concentration, the pancreas releases hormones to help the blood glucose level go back to normal. For example, if the blood glucose level is too high, insulin will be released and some glucose can be converted into glycogen and store in liver. On the other hand, if the blood glucose level is too low, glucagon is released and glycogen is converted back into glucose.
For body temperature, if the temperature is too low, our hair stands upright so more heat is trapped. In addition, our arterioles under skin contracts too so less heat is lost to the surroundings. On the other hand, if our body temperature is too high, our hair stays flat so heat can be transported away quickly, and our arterioles dilate, so more blood flows to the skin surface and more heat will be lost.
Last but not least, if the water volume in body is too low, antidiuretic hormone is released and more water is absorbed by the kidney so less water is lost. On the other hand, if the water volume is too high, antidiuretic hormone is inhibited so less water is reabsorbed back into the kidney.
