Nicolas steno (1638-1686) recognized that fossilized shark teeth were formed from actual prehistoric shark teeth. how did his observations contribute to the development of the atomic theory? a) steno explained that objects could change their composition without changing form. b) steno observed that similar fossils were found in the same strata within a rock formation. c) steno observed that when liquids solidify around a solid object, they conform to the solid's shape. d) steno explained that molecules from the bodies of prehistoric animals decomposed into calcium carbonate.

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.
