Answer:
The condition of the Earth had to become favourable before it could support any form of life.
The formation of the different layers around the earth like the ozone layer was necessary before life could originate. Primitive species such as some prokaryotes were able to live in hydrothermal conditions during the initial times. With the passage of time, as the concentration of oxygen increased due to photosynthetic prokaryotes, situations became favourable for eukaryotic organisms to arise.

Answer:
A) Sedimentary
B) Weathering
Explanation:
A sedimentary soil/rock is formed when carrying agents such as wind or water carries rock pieces or soils particles from faraway places and deposit them at one place through a process known as lithification. However, increased pressure and temperature causes weathering of rocks. Changing temperature causes a rock to expand or cool alternatively thereby giving rise of internal stresses. While exfoliation is caused on increasing pressure.
The shivering reflex is used to maintain the homeostasis. This happens when the core body temperature drops. as the result of the reduce temperature, homeostasis is triggered and warmth is caused by the movements of the muscles around the vital organs. <em />
