Answer:
Physical change
Any change to the physical properties of a substance is called a physical change.
Physical changes are usually reversible as no new substance is formed. It is the same substance but with changed physical properties.
Chemical change
A change in which one or more new substances are formed is called as a chemical change.
Usually a chemical change involves a chemical reaction, which forms new products.
Example : Rusting of Iron, or burning wood.

thousands of years
Explanation:
A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.
A delta is a place where river enters or drains into the sea with many mouth or outlets.
Deltas are depositional terrain full of dis-tributaries.
- For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
- The entering stream must be large enough and have large amount of sediment.
- The river mouth must have been cut to the same level with that of the drainage basin.
- Most rivers such terrain should be at their lower course where they flow with very low velocity.
- Wave action should be minimal along such coasts.
These processes takes several thousands of years if not millions.

The answer would be sewer systems.
Answer:
The cell will shrink due to osmosis.
Explanation:
As in given question the salt concentration are much more inside the cell, than outside. In order to maintain equilibrium. the water inside the cell will start flowing outside in order to maintain equilibrium, causing shrinkage of cell. The ability of a cell to divide or function will reduce because of water loss. This phenomenon is seen in case of hypertonic solution. Water will start diffusing from the higher concentration to the lower concentration.
This process is known as synaptic pruning.
Synapse pruning is the process when the synapses are eliminated and it occurs usually in the early childhood. Synapses that are eliminated are the ones that organism no longer needs. Synaptic pruning process is regulated and influenced by environmental factors.
