Capital expenses are either amortized or depreciated depending upon the type of asset acquired through the expense. Tangible assets are depreciated over the useful life of the asset whereas intangible assets are amortized.
The area near the surface of the earth can be divided up into four inter-connected geo-spheres: the lithosphere, hydrosphere, biosphere, and atmosphere.Scientists can classify life and material on or near the surface of the earth to be in any of these four spheres.The names of the four spheres are derived from the Greek words for stone (litho), air (atmo), water (hydro), and life (bio).ost of the planet's life is found from three meters below the ground to thirty meters above it and in the top 200 meters of the oceans and seas. The atmosphere is the body of air which surrounds our planet. Most of our atmosphere is located close to the earth's surface where it is most dense.
The innermost four planets of our solar system are called the âterrestrialâ planets, which comes from the word âtelluricâ. It is derived from the Latin words âterraâ and âtellusâ, used to refer to Earth. The terrestrial planets (in order of their distances from the Sun) are Mercury, Venus, Earth and Mars.They are made mostly of silicate rocks and metals, with solid surfaces and atmospheres that range from thick (on Venus) to very thin (on Mercury). The terrestrial planets in our solar system orbit relatively close to the Sun, this gives them their other name; the âInner Planetsâ. 2  Earth is the most hospitable to life. 3  Mars may have supported life in the past, but there is no evidence that conditions have ever been life-friendly on Mercury or Venus.
