Why do glaciers grow slowly in Antarctica?
With so little precipitation, it is difficult for glaciers to grow more quickly. What this also means is that the existing glaciers are millions of years old.
Why do glaciers grow and shrink?
Glaciers grow when more snow accumulates in a glacier than melts or evaporates. Glaciers shrink when more ice melts or evaporates than accumulates through snowfall. Changes in temperature, precipitation, and environmental conditions can influence the growth and shrinkage of glaciers.
When glaciers grow global sea level?
When glaciers grow, they typically store more water as ice, which leads to a decrease in global sea levels. This occurs because the water that would otherwise contribute to sea levels is trapped in the ice. Conversely, when glaciers melt, this process releases stored water back into the oceans, causing sea levels to rise. Therefore, the balance between glacier growth and melting is crucial for determining global sea levels.
What conditions cause glaciers to grow larger and advance?
Glaciers grow larger and advance when accumulation of snow and ice exceeds melting and sublimation. This typically occurs in colder climates where temperatures remain low enough to prevent significant melting, especially during summer months. Additionally, increased snowfall can enhance accumulation, while factors such as elevation and latitude also influence glacier growth. These conditions create a positive mass balance, leading to the forward movement of glaciers.
What are the different types of glaciers?

Why do glaciers grow slowly in Antarctica?

How do glaciers weather valleys?
they melt and put water in the valleys and they grow
Why do glaciers grow slow in antarctica?
Antarctica is a desert with about five percent humidity. This means that very low amounts of moisture are available to be frozen into glaciers.
Did human have to wait for glaciers to spread before they could grow crops?
No. There were no humans when it was the time of glaciers and it will be thousands of years before man learns to farm.
Two factors that effect the size of glaciers?
Two factors that affect the size of glaciers are temperature and precipitation. Higher temperatures can cause glaciers to melt faster, while increased precipitation can help glaciers grow by adding more ice mass.
Is the formation of glaciers is directly controlled by climate?
Yes, the formation of glaciers is directly controlled by climate. Glaciers form in areas where snowfall exceeds snowmelt and evaporation, allowing the snow to accumulate and eventually compress into ice. A colder climate with consistent snowfall and cool temperatures is necessary for glaciers to form and grow.
Why do glaciers grow and shrink?
Glaciers grow when more snow accumulates in a glacier than melts or evaporates. Glaciers shrink when more ice melts or evaporates than accumulates through snowfall. Changes in temperature, precipitation, and environmental conditions can influence the growth and shrinkage of glaciers.
Would cold winters or cool summers cause glaciers to grow?
Yes, because the gather of snow fall.
Did humans have to wait for glaciers to spread before they could grow crops?
no because they are made of water and they should not be in the way
How can glaciers cause disposition?
When glaciers move as they grow, they grind the ground and rock underneath them. These pieces are pushed forward while they grow. When they final begin to melt, the water that is in the glaciers flows out from underneath them. This often carried sand and small bits of gravel. As they melted further and faster, larger gravel and stones wash out. Finally very large rocks and boulders are left behind. All of these are called deposition.
Why do sea levels fall as glaciers grow larger?
The amount of water on the planet stays the same. If huge amounts of this water is frozen on land, in glaciers, then it means that there is less water in the oceans, and sea levels are lower.
Glaciers form and grow when the snowfall from one season does not melt and is later covered and compressed into ice by the snowfall what seasons?
This is true
