Which of the following is true concerning natural resources? a. natural resources are not recycled. b. natural resources are only inorganic. c. they are part of natural processes. d. they only incorporate one form of matter.

The correct answer is C. They are part of natural processes.

Natural resources are termed as resources which are known to exist without humankind action.

For example, forces, electrical properties, magnetic and gravitational.

Those components and material are also classified as natural resources. Natural resources can exist either as air, as living organism or as fresh water.

Natural resources can be categorised by renewability, stage development, and as source of origin.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
