The map below shows a section of the state of florida. the red line indicates a geologic feature found in florida. this geologic feature can best be described as a large stream of fresh water that drains surface run-off from the land into large bodies of water such as oceans and lakes. the geologic feature indicated in the map is known as a. a levee. b. a river. c. a pond. d. a coastline.

B. A river.

Explanation:

A river is a geological entity characterized by a freshwater stream that has a flow influenced by the force of gravity that allows that water to flow towards an ocean, a lake, another river or the sea, that is, a river it is a large stream of fresh water that drains runoff from land to large bodies of water, such as oceans and lakes.

A river can also flow into a dry land portion, although it is a rarer situation to happen, or it happens before the river connects to any body of water.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
