What Are Glaciers?

Glaciers are massive ice masses formed by falling snow that can be as tiny as soccer fields or as long as hundreds of kilometers.

Although these freezing white masses appear to be rock solid, you’ll be startled to learn that they aren’t stable and continue to drift across the area they once occupied, just like rivers do.

As a result, they’ve been given the moniker “ice rivers.”

Types of glaciers

There are two sorts of glaciers.

  1. Alpine glaciers and
  2. Ice sheets/ Continental Glaciers

Alpine Glaciers:

Alpine glaciers, also known as valley glaciers or mountain glaciers, originate along mountain sides and flow down valleys.

Alpine glaciers are found in the high mountains of every continent except Australia.

Ice sheets :

An ice sheet is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 sq. km.

When ice sheets form, they traverse the limits of mountain ranges due to pressure differences.

They start by forming a dome in the center, then radiate out in all directions, covering landforms such as hills, mountains, and valleys.

Today, continental glaciers cover most of Antarctica and the island of Greenland.

But, more importantly, How Are The Glaciers Formed?

Let me explain, The Best Step By Step Guide How Are The Glaciers Formed

Glaciers form when a considerable amount of snow gathers each year and does not melt.

When snow falls, it begins to compress, or grow denser and more densely packed, and gradually transforms from light crystals to hard ice pellets known as neve.

When new snow falls on top of the old, it buries the material beneath it, compressing it even more and converting it into dense, wet eyes known as fern, a transitional state between snow and glacier ice.

Fornication is the action of snow condensing becoming glacial fern. Layers of fern developed on cover of each other over time, after many years and several snowfalls.

And when the ice has thickened sufficiently. The glaciers are formed as fern grains merge into a massive amount of solid ice, which could take over a hundred years before we see them slowly free-flowing on calm water.

However, don’t be fooled by their movements.

Yes, despite their gentle movement, glaciers are a force to be reckoned with, capable of destroying practically everything in their path.

Glaciers are stronger than dense forests, powerful slopes, and mountainsides.

When the glaciers advance, the ground beneath and surrounding them erodes or wears away. These white masses transport massive amounts of rock, soil, and clay, with some stones as large as elephants.

Glaciers Melted

But here’s something to keep in mind, my friends:

Even though most people become aware of how rapidly glaciers have indeed been melting in recent years, the earth underwent a “Little Ice Age” between the 17th and 19th centuries. Because of a lengthy period of colder temperatures, glaciers were able to develop and flourish throughout this time.

Glacier ice now holds nearly three-quarters of the world’s fresh water. Many people believe that if global temperatures rise to the point where glaciers melt, sea levels will rise dramatically, causing flooding along coastal lines.

Yes, sea levels have been rising year after year, and scientists believe that melting glaciers may be a major contributor.

It’s still unknown how much the sea level will rise as a result of melting glaciers.

Causes of melting glaciers.

But one thing is certain: the earth’s average temperature has been steadily rising in recent years. And glaciers are crucial markers of global warming and climate change in a variety of ways that could have serious consequences for people as well as other animals.

Effects of melting glaciers on the environment

Yes, rising freshwater levels will have an influence on the ocean ecology.

Many species that rely on salt water for existence, such as corals and other saltwater fish, may not be capable of adapting to a more freshwater home.

So, in order to prevent the earth from drowning, we must reduce global warming.

Also, when it comes to physical aspects, the greatest glacier in Antarctica, Lambert’s Glacier, is around 270 miles long and 60 miles wide.

I hope you learned something interesting about glaciers.

20 Fun Facts About Glaciers

Here you better know 20 Fun Facts About Glaciers:

  1. Falling snow accumulates over time to build massive, thicker ice structures, which are known as glaciers. A glacier’s formation is a painstakingly slow process that takes hundreds of years.
  2. Glaciers cover about 10% of the earth’s surface, or 5.8 million square miles (15 million square kilometers), and are significantly more important than most people believe. Because glaciers provide for almost 75% of the world’s fresh water supply, the melting of an estimated 90% of the world’s glaciers is a major worry.
  3. The age of glaciers is some of the most amazing facts about them. (Scientists believe the age of the Antarctic Ice Sheet should be at least 30 million years old, while the Greenland Ice Sheet is only 2.) 5 million years old.
  4. 99 percent of all glacial ice is found in the Arctic and Antarctic. The Greenland Ice Sheet, on the other hand, covers 660 square miles (1,710,000 square kilometers), or nearly 80% of Greenland’s area.
  5. Chile also has a sizable glacier population, with 31,000 of them, accounting for more than 80% of all glaciers in South America.
  6. There are glaciers in 47 countries.
  7. Glacier ice has a different appearance than ice cubes or ice from our freezers because of how solid it develops.
  8. Glaciers act as a filter, absorbing red and yellow light while reflecting blue, explaining why they appear blue.
  9. Older glacial ice is denser and appears darker.
  10. There are over 100,000 glaciers in Alaska, according to estimates. The majority of them go unnamed.
  11. Before being engulfed by a glacier, mountain valleys were often “V” shaped. The valley widens and deepens with glaciers, forming a “U” shape.
  12. Consequently, if all the earth’s land ice melted, global sea levels will indeed rise by 230 feet (70 meters), almost same height as a 30-story building. Attempting to slow the melting of glaciers is crucial for the earth as a whole, and experts from all around the world are working on it.
  13. The ice inside glaciers changes shape and moves due to gravity.
  14. Glaciers can advance more than 50 feet each day. The Jakobshavn Glacier in Greenland broke a new world record by moving an astonishing–by glacial standards, at least–150 feet per day in the summer of 2012.
  15. Glaciers flow from higher to lower elevations. They do, however, flow so slowly that if you were standing next to a glacier, you would probably not see it moving.
  16. Glaciers can flow all the way down to the sea in cold, snowy climates. Icebergs are fragments of glaciers that break off and float in the ocean.
  17. Glaciers are largely formed of ice, but as they travel, they gather up particles.
  18. The OMG (Oceans Melting Greenland) project of NASA investigates the various ways in which ocean waters affect marine glaciers.
  19. Glacier melt feeds lakes, rivers, and oceans with nutrients. Those nutrients can cause phytoplankton blooms, which are the foundation of aquatic and marine food systems.
  20. Meanwhile, gradual glacier melt protects plant and animal habitats along streams. As a result, glaciers frequently have an unintended impact on animals and fisheries.
