The physical systems of the earth include the lithosphere, the hydrosphere, the atmosphere and the biosphere.
The hydrosphere consists of the earth's water. Approximately 70% of the earth's surface is water. It is found in oceans, lakes, rivers ponds, ice and ground water.
The Lithosphere consists of the solid surface that covers the Earth. Features such as hills, mountains, plateaus, plains and ocean basins are land forms covering the lithosphere.
The atmosphere consists of the thin layer of gases that surround the earth and rises up to 100 miles from the earth's surface, beyond which is outer space.
The biosphere consists of all things living on the surface of the earth and includes animals and plants.

In general, the human impact on the natural resources is negative.
Explanation:
The humans constantly stride to be as developed as possible and to live at a higher standard as possible. This means that the economies constantly need to progress, develop, and grow. In order for this to be achieved the humans need natural resources, mostly for energy, but also for numerous other things.
Because the demand for natural resources is constantly on the rise and it seems that it will be in the future as well, the natural resources are spent at a rate much faster that the time needed for them to replenish naturally. This leads to decrease of the natural resources and eventual putting end to some of them, in a process that benefits the humans for now, but on the long run can only be seen as destroying and over-exploration of these resources.

Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock.
