Nature (pets and nature by modehbayoblog)

The term "nature" may refer to living plants and animals, geological processes, weather, and physics, such as matter and energy.

The term is often refers to the "natural environment" or wilderness—wild animals, rocks, forest, beaches, and in general areas that have not been substantially altered by humans, or which persist despite human intervention. 

The word nature is derived from the Latin word natura, or "essential qualities, innate disposition", and literally means "birth".

Natura was a Latin translation of the Greek word physis (φύσις), which correlated plants, animals, and other features of the world as developing of their own accord.

For, example, manufactured objects and human interaction are generally not considered part of nature, unless qualified as, for example, "human nature" or "the whole of nature". 

This more traditional concept of "nature" implies a distinction between natural and artificial elements of the Earth, with the artificial as that which has been brought into being by a human consciousness or a human mind.

Much attention has been given to preserving the natural characteristics of Hopetoun Falls, Australia, while maintaining visitor access.

The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socratic philosophers, and has steadily gained currency ever since.

A natural environment encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth

A natural environment is a type of an environment where human impact or interaction has been extremely limited.

In actual sense in the discuss of nature it could involve the critical and soft part of it from scariest animals you never knew existed to the beautiful view of water flows and so on .

THE EARTH 

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets.

Broadly speaking, the Earth has four layers: the solid crust on the outside, the mantle and the core -- split between the outer core and the inner core.

The crust

“Crust” describes the outermost shell of a terrestrial planet. Our planet's thin, 40-kilometer (25-mile) deep crust—just 1% of Earth's mass—contains all known life in the universe. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals.

The mantle 

The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.

The core 

The solid inner core is situated about 3,200 miles below the Earth's crust and is separated from the semi-solid mantle by the liquid outer core, which allows the inner core to rotate at a different speed from the rotation of the Earth itself. With a radius of almost 2,200 miles, Earth's core is about the size of Mars.
