Answer:An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years.
Explanation:These global cooling periods begin when a drop in temperature prevents snow from fully melting in some areas. The bottom layer turns to ice, which becomes a glacier as the weight of accumulated snow causes it to slowly move forward. A cyclical pattern emerges in which the snow and ice traps the Earth’s moisture, fueling the growth of these ice sheets as the sea levels simultaneously drop.

Gradient is an area of ground that tends evenly upward or downward.
A stream gradient can be defined as an area of water that that tends evenly upward or downward of the stream and it is measured by the difference in elevation between two points on a stream divided by the distance between the two points that the water actually flows.
The gradient influences the speed in respect to time of the stream. The steeper the gradient, the higher will be the speed of the of the flow.
