15 POINTS!! In the South Texas Plains, the Rio Grande River flows along the southern border of the state. The Rio Grande shapes the region through the processes of weathering, erosion, and deposition. Which of the following is an example of the river forming a depositional feature?
A.
As the water's speed decreases along the inside edge of a curve, sediment is laid down to form a point bar.
B.
As the water flows along the outside edge of a curve, it removes rock and soil from the river bank.
C.
As the water's speed increases, it scours deep grooves in the muddy river bottom.
D.
all of these

A) As the waters speed decreases along the inside edge of a curve, sediment is laid down to form a point bar

Explanation:

Depositional landforms are the visible evidence of processes that have deposited sediments or rocks after they were transported by flowing ice or water, wind or gravity. 

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.
