What are glaciers made up of?
Glaciers are not made of rock; they are made of ice. Glaciers can contain rocks, but not of any particular type. Rather, they carry whatever type of rock they are going over or have gone over.
Ask us What force is present at a divergent boundary?
A divergent boundary are two tectonic plates that are moving away from each other, rather than into each other. This can cause rifts, valleys, and ocean ridges.
Why can crevasses in glaciers only be 50M deep?
Plastic flow occurs below that depth.
Why are glaciers called nature's bulldozers?
Because glaciers are huge chunks of ice that can ruin or tear down houses Only if you're daft enough to build your house right in front of a growing glacier! They are rivers of ice, not huge chunks, fed for the duration of their lives by snow avalanching off the mountain ridges around their heads, or by sustained snow-fall on an ice-cover. They are called "nature's bulldozers" (are they? by whom?) because they carve out great U-shaped valleys, but most of the material they move is carried on them or dragged along underneath, then washed downstream by melt-water from their snouts, rather than being pushed in front of the ice. So it's a misleading colloquialism.
Why are mountain glaciers shrinking?
As the glaciers melt, additional water is added to the oceans. This new addition can alter the tempture and the currents of the oceans. At the same time, this additional water causes the global water levels to rise. The rising water is a threat to all coastal cities and threatens to change the shape of the current global landmass. It can also effect the life of many animals by adding fresh water to salt water and changing the concentrations so it is no longer life sustaining for its current occupants.

Are there any famous glaciers near Antarctica?
Antarctica is a continent that covers 10% of the earth's surface. Ninety-eight percent of it is covered with an ice sheet. The mountainous terrain of the continent means that there are thousands of glaciers on the continent. "Near Antarctica' is the Southern Ocean, which may be home to icebergs calved off continental glaciers. Rather than 'famous glaciers', Antarctica is home to ice shelves, the most famous, perhaps, being the Ross Ice Shelf, which is about as large as France.
Is there ice in Costa Rica?
If you mean ice as in freezer ice,then yes there is! But here are no ice burgs,snow,ice glaciers or any formed ice,rather then the ice in the freezer.
What does Antarctica look like?
It has a lot of ice, it's very cold, and rather uninhabited.
What plain is in st thomas?
St. Thomas, a part of the Virgin Islands, is characterized by rolling hills and valleys rather than plains. The terrain is mainly hilly with mountains, forests, and coastline.
Why do you think ancient Chinese cities were founded in the eastern low lying areas rather than in the west?
The river valleys broadened as they flowed east out of the western mountains, and so supported the burgeoning population and growing cities there.

A divergent boundary are two tectonic plates that are moving away from each other, rather than into each other. This can cause rifts, valleys, and ocean ridges.

What is Sediment of different sized particles left by ice from glaciers is called?
Glacial Till (used to be called 'Boulder Clay'). Sometimes Moraine Debris, but terms like 'moraine' refer to the topography of the deposit rather than the material itself.
What is the name of a map showing hills and valleys by shading rather than by contour lines?
The type of topographical map referred to is known as a relief map or raised-relief map. These maps use shadowing to simulate texture and terrain three-dimensionally.
