How could an area near the equator have a glacier?
It is possible that glaciers can exist at the Equator if they are at high enough in elevation that the air becomes cold again and snow can fall. …
What types of climatic conditions are needed for glaciers to form?
Glaciers require very specific climatic conditions. Most are found in regions of high snowfall in winter and cool temperatures in summer. These conditions ensure that the snow that accumulates in the winter is not lost during the summer. Such conditions typically prevail in polar and high alpine regions.
Under what conditions will the front of a glacier remain stationary under what conditions will the front of a glacier remain stationary?
Glacial fronts remain stationary when melting and snow accumulation are equal.
What are glaciers near the equator called?
Alpine glaciers are found at high altitudes, and they sometimes occur relatively close to the equator. They accumulate snow at their tops and flow downhill.
Was the equator hot during ice age?
The results indicate that the mean annual temperature during the last ice age was 5.4 degrees C plus or minus 0.6 degrees C (8.6 degrees F to 10.8 degrees F) lower than today, suggesting that equatorial South America did cool significantly at low altitudes, the scientists said.
What is needed for glaciers to survive and grow?
Growing a glacier requires two essential ingredients: adequate snow fall and a cool climate. In warm climates, high mountain peaks may recieve heavy snowfall in the winter, only to have it melt away during the warm summer months. A cool climate means cool summers.
What are two ways that glaciers move?
Glaciers move by a combination of (1) deformation of the ice itself and (2) motion at the glacier base. At the bottom of the glacier, ice can slide over bedrock or shear subglacial sediments.
Where are the glaciers near the equator?
Let’s look at the glaciers near the earth’s equator and you’ll find some on each continent that straddles the equator, i.e. Asia, Africa, and South America. They are: Carstensz Glacier, near the peak of Puncak Jaya, Indonesia, island of New Guinea; 04°05’S, 137°11’E; elevation ~4,700 m.
Is there ice at the equator?
Think equator, the place on earth where each day has 12 hours of daylight and 12 hours of night, no winter or summer seasons, just a tropical paradise on earth. Except for the higher elevations, where there are glaciers. Yes, real natural ice right there on the ground courtesy of Mother Nature.
Were tropical areas once covered by glaciers?
The finding, detailed in the March 5 issue of the journal Science, also has implications for the survival and evolution of life on Earth through this bitter ice age. Geologists found evidence that tropical areas were once covered by glaciers by examining ancient tropical rocks that are now found in remote northwestern Canada.
What transfer glacial ice from hanging glaciers to the valley floor?
Avalanches and icefalls transfer glacial ice from hanging glaciers to a larger glacier beneath them, or directly to the valley below. An ice sheet spreads out from its center.
