What change would occur in a glacier if average annual temperature rose and the precipitation decreased?
The glacier would retreat. The rise in temperature would cause the glacier itself to start melting, and in addition, would lower the amount of precipitation in the form of snow at the top of the glacier. It would be rain instead. Lowering the precipitation would cause less ice formation as well and would also contribute to the glacier retreating.

What are some external forces of a glacier?
Some external forces acting on a glacier include temperature, precipitation (snowfall), wind, and sunlight. These factors can influence the accumulation, melting, and movement of glacial ice.
How fast is the fox glaciers?
Fox Glacier in New Zealand moves at an average speed of about 1 to 5 meters (3 to 16 feet) per day, depending on various factors such as temperature, precipitation, and the glacier's underlying conditions. This movement can vary, with periods of faster flow during warmer weather or after heavy rainfall when meltwater lubricates the glacier's base. The glacier's dynamic nature is a result of the interplay between accumulation of snow and ice and its melting at lower elevations.
What condition is most important to the growth of glaciers?
The most important condition for the growth of glaciers is a balance between snow accumulation and snowmelt. When more snow falls in a glacier area than melts during the summer, the glacier can grow and advance. Temperature and precipitation patterns also play a significant role in glacier growth.
When ablation exceeds accumulation the glacier is?
When ablation exceeds accumulation, the glacier is in a state of retreat. This means that the loss of ice and snow through melting, sublimation, and calving is greater than the amount of new snow and ice being added. As a result, the glacier's mass decreases, leading to a reduction in its size and extent over time. This imbalance can be influenced by factors such as temperature increases and changes in precipitation patterns.
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.

How does glacier survive?
by having the proper temp and precipitation
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.
How long does a glacier take to melt?
It depends on conditions. A long period of above-average warm and dry weather can cause a glacier to shrink. As the ice gets thinner, the warm meltwater and increased exposure to rocks (which absorb sun energy) quickens the pace at which the glacier recedes.
What condition is most important to the growth of glaciers?
The most important condition for the growth of glaciers is a balance between snow accumulation and snowmelt. When more snow falls in a glacier area than melts during the summer, the glacier can grow and advance. Temperature and precipitation patterns also play a significant role in glacier growth.
What is The Temperature of a glacier?
The temperature of a glacier varies depending on factors like altitude, season, and climate. The surface temperature of a glacier can range from below freezing to slightly above freezing, while the temperature deep within the glacier can remain below freezing even during the summer.
What is the temperature of a glacier in Antarctica?
Inside a glacier it is exactly 0° C (the temperature at which water freezes to ice). On the surface of a glacier it can be anwhere from +25° C (if you are really lucky) to -60° C.
What is the relationship between size and temperature?
Temperature influences glacier size.
How does a cloud turn into a glacier?
When snow accumulates on a mountain, it compacts over time to form layers of ice. These layers can gradually increase in thickness to become a glacier. The process involves the gradual transformation of snow into dense, compacted ice due to pressure and temperature changes.
What is the temperature necessary for a glacier to melt?
A glacier is ice, which melts just above 0 Celsius or 32 Fahrenheit.
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.
What determines the shape of a glacier?
The shape of a glacier is primarily determined by the interplay of gravity, the underlying topography, and the accumulation and melting of ice and snow. Glaciers flow downhill due to gravity, adapting their form to the landscape they traverse, which can include valleys, ridges, and other geological features. Additionally, variations in temperature and precipitation affect the glacier's mass balance, influencing its thickness and extent. As a result, the combination of these factors creates diverse glacier shapes, from broad, slow-moving ice sheets to steep, narrow valley glaciers.
