It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. The skin's structure is made up of an intricate network which serves as the body's initial barrier against pathogens, UV light, and chemicals, and mechanical injury
Skin also functions as a large storeroom for the body: The deepest layer of skin can store water, fat and metabolic products. And it produces hormones that are important for the whole body.
i) The sky is composed of the atmosphere, which forms an airy barrier between the earth and beyond. The atmosphere is made up of gasses. Its main ingredient is nitrogen, but it also contains 21 percent oxygen and 1 percent water vapor. Traces of other gases like carbon monoxide and argon are part of the atmosphere too.
ii) Condensation in the air. Air contains water molecules. Clouds exist in the atmosphere because of rising air. As air rises and cools, the water in it can "condense out," forming clouds.
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor, then rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation
