Stopping the Melting

What is a glacier?
A glacier is a giant mass of ice and snow, or a river of ice.
100
What is an ice cap?
Ice caps are sheets of ice spread over a large area.
100
What is happening to the sea level?
The sea level is rising.
100
What are 3 life forms affected by global warming-induced glacial melt?
Ice worms, polar bears, emperor penguins, mosquitoes, algae, birds, fish, and humans are all examples of creatures harmed by climate change in the glaciers. Of course, everything is connected on the food web, so the answer could also be "almost all of them" (but you need 3).

What is the main thing we can do to stop the glacial melt?
Drastic glacial melt can be stopped by taking measures to reduce global warming.
200
How are glaciers formed?
Glaciers are made of compacted layers of snow, which falls and hardens in the cold of winter.
200
What do ice caps do in nature?
Ice caps reflect heat back into space, cooling the planet.
200
Why is the sea level rising?
The glaciers are retreating too much, and the meltwater flows into the ocean
200
Why will ice worms be affected?
Ice worms spend their whole life living on ice and feeding on glacial algae.
200
How can global warming be stopped?
reduce greenhouse gases and the burning of fossil fuels.
300
What do glaciers do in nature?
Glaciers hold freshwater, which melts in the summer. They also erode mountains, depositing sediment as they move.
300
What do ice caps provide for people?
Ice caps are a source electricity and freshwater.
300
How will the rising sea level effect coastal towns?
Saltwater can seep into the rivers and the ground water, contaminates crops, causes erosion and flooding, and destroys habitats.
300
What similar affects do the polar bears and ice worms have because of melting glaciers?
They both spend most of their time living on the ice.
300
What are three things that can be done to hinder global warming?
Use less energy, use environmentally friendly alternatives, and try to not pollute.
400
How do they help the world?
Glaciers provide water for many areas without much rain and without them there would be major problems.
400
How do ice caps form?
Ice caps form like glaciers—snow compacts and forms hard layers of ice
400
About how much would the sea level rise if all glaciers melted?
The sea would rise around sixty-six meters.
400
What does early glacial retreat do for animals and their offspring?
When glaciers retreat too early in the breeding season, breeding failure occurs. Baby animals die, too.
400
What can corporations do to help fight global warming?
Factories and heavily fossil-fuel reliant/greenhouse gas producing companies can find ways to reduce their carbon footprints by exploring more environmentally-friendly solutions and investing in cleaner energy sources.
500
What are glaciers sometimes called and why?
Glaciers are sometimes known as "rivers of ice" due to their movement.
500
What is the difference between glaciers and ice caps?
Ice caps are one kind of glacier, one of two types. Ice caps typically spread from the center and are slightly dome shaped.
500
Under the extreme circumstance of having all glaciers melt, where would San Diego be?
San Diego would be underwater.
500
Which mountains are receding, leaving the mosquitoes to travel to places they have not previously been?
Rwenzori Mountains

What is one renewable source of energy (possibly learned from past presentations)?
Some alternate sources of energy include cold fusion, biofuel, geothermal energy, hydrogen, solar power, and wind power.
