Answer:
Conditions at the base of a glacier increase glacial flow velocity -
Steeper slope
Smooth rock / glacier contact
Colder basal water temperature.
Explanation:
Steeper slope and smooth rock/glacier contact will increase glacial flow velocity because higher the steepness higher the velocity and smoothness will apply less friction.
Due to decrease in ice thickness the load at the bottom of the glacier will decrease, and we know that the glacier flows under the load of itself, so lesser the load lesser the velocity.
Colder basal water temperature will generate less amount of melt as compared to warmer basal water temperature, so in colder condition, glacial flow velocity will not be increased.
Not quite sure what you're asking, but erosion and deposition do create land forms. For example: erosion along the coastline may result in the formations of arches, stacks, stumps, wave cut platforms, caves, etc. Deposition, different amount of it and in certain areas, under the influence of either destructive or constructive waves, will form beaches - ones with a lot of beach, through a lot of deposition, or slopes beaches where destructive waves have crashed upon the beach. Hope this is what you're looking for.

South America is a continent that has a steady rise in its population. It has around 415 million people and if the trend of rise continues, very quickly the continent will reach the mark of half a billion people.
The biggest, and also the most populous country in South America is Brazil. Brazil has an estimated population of around 209 million people, and it is growing population. Brazil's population accounts for approximately half of the population on the continent.
