This document describes two rare weather phenomena: ice balls and snow rollers. Ice balls occur along shores after heavy snowfalls, where waves turn snow to ice balls up to the size of footballs. Snow rollers are cylindrical snow formations that form when a 2cm layer of powdery snow glides easily on ice or frozen surfaces under winds of 40km/h, causing snow to roll into cylinders up to 70cm in diameter. Both require specific temperature and environmental conditions to form.
Winter ecology notes frost, snow, and icemikelink45
The basic aspects of winter revolve around water and how it freezes and how our bodies try to prevent its freezing. In the exterior world ice, frost, snow are expressions of the winter season.
in this presentation I will discus about the glacier, different type of glacier, formation of glacier and its movement from height toward lower area and supply water to our rivers
A look at the factors of winter weather and the challenges of a changing climate. Many of the notes refer to MN, but are true across the northern landscape
This topic is all about Glaciation. This includes; the causes of glaciation, the origin of glaciers, formation, primary types, movement, the erosional, transportation and depositional mechanisms. This also includes the common landforms brought by glaciers.
1. A glacier is a large, long-lasting mass of ice formed on land that masses downhill under its way.
Glacier is part of the earth’s hydrosphere.
Along with the sea, ice glaciers are known as the cryosphere.
2. GROUP OF GLACIER:
They fall into two general groups based on their form size and flow characteristics
3. Alphin glacier that is surrounded by mountains is called an alpine or mountain glacier.
Glaciated valleys are through like U-shaped with board floors and relatively smooth, and steep sides
The valleys may contain littered debris or debris shaped as moraines with a swampy appearance.
There may be taken gouged out of the rocky floor or formed by debris within the valley.
Cirque Glacier: Bowl-like hollow structures are called cirque glaciers. They are formed inside the mountains and tend to move towards the valley. A glacier that forms in a cirque is a cirque glacier.Piedmont Glacier: When the steep valley glaciers spill into flat plains, then a piedmont glacier occurs e.g Malaspina glacier that falls into Yakutat Bay, Alaska.Hanging glacier: When the major valley glacier thins out, that becomes a hanging glacier.Tidewater glaciers: These are valley glaciers that reach the sea, and they provide breeding habitat for seals. These glaciers are the ones that form small icebergs.
4. Continental glaciers are those vast masses of ice sheets covering stretches of land. Such glaciers flow over large areas that are unconfined, where they bury the landscapes underneath
Today, continental glaciers are only present in extreme polar regions: Antarctica and Greenland Historically, continental glaciers also covered large regions of Canada Europe and Asia, and they are responsible for many distinctive topographic features in these regions.
The ice sheet blankets 81% of Greenland and 90% of Antarctica.
FORMATION AND FLOW:
IMPORTANCE OF CONTINENTAL GLACIER:
Glaciers are an essential indicator of the study of environmental change, thereby making people aware of the increasing global warming. Due to the continuously growing industrialization, and use of automobiles, there is a rising graph of air pollution triggered by the emission of carbon monoxide and other harmful greenhouse gases. The outcome of all these is the catastrophic increase in global warming and greenhouse gases.
Glaciers come in a huge range of shapes and sizes. Different glaciers, and even different parts of the same glacier, can have a variety of different thermal, hydrological and dynamic characteristics. Glaciers occur in locations ranging from the poles to the equator, and most parts of the world have experienced the direct effects of glaciation at some time in the past. Glaciers currently occupy less of the planet than they have done in geological history, but nevertheless exert a profound influence on the global environment. Our developing understanding of glaciers will play an important role in our understanding of the global environmental system

Hadj Ounis's most notable work is his sculpture titled "Metamorphosis." This piece showcases Ounis's mastery of form and texture, as he seamlessly combines metal and wood to create a dynamic and visually striking composition. The juxtaposition of the two materials creates a sense of tension and harmony, inviting viewers to contemplate the relationship between nature and industry.
5. This freak of nature occurs after heavy snow falls
along the shores of large lakes and oceans. The
snow is turned into ice by the motion of the waves,
creating huge frozen ice balls.

8. Thousands of balls of ice the size of a football,
huddle along the shore in a wonderful show. For this
to happen the water temperature should be 0 ° C. A
phenomenon known as "Lolly" by the fishermen of
the Canadian Island of Cape Breton.
18. A curious meteorological phenomenon of cylindrical snow
formations known as SNOW ROLLERS is rare because the
precise conditions must be present for their formation.
23. -The frozen surface or ice covered area should glide
with ease to make a roller.
-The ice must be covered with a 2 cm moist layer
thick powder snow and the temperature must be
close to the point where ice melts.
24. -The air temperature must be equal to or slightly
above freezing, between 0 and 1 ° C.
-The wind must be approximately 40 km / hour to
roll the snow.
25. -A gust of wind takes the snow along like a spoonful of
ice cream. Each gust of wind increases its size.

28. The size of the cylinders may reach several
centimeters and one roller had a diameter of 70
cm.

33. Finally, when the roll is too heavy to be
pushed by the wind or comes against an
obstacle, it stops, leaving a trail behind.

39. Gravity also forms snow rollers. The snow falls from a
tree on a slope and rolls down, forming a sphere.
