What are the causes and dangers of the melting polar ice caps?

Causes of Melting Ice Glaciers

• Burning of fossil fuels. The burning of fossil fuels has resulted in the buildup of greenhouse gases in the environment thus influencing the warming trend because they trap heat in the atmosphere.
• Oil and gas drilling.
• Deforestation.
• Ice breaking ships.

What happens if the Arctic ice cap melts?

“If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly,” the Museum of Natural History site reads.

What causes the ice to melt answer?

As energy is transferred to the water molecules in the ice, the motion of the molecules increases. The motion of the molecules increases enough that it overcomes the attractions the water molecules have for each other causing the ice to melt.

What is causing the ice caps to melt?

Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.

What happen when ice melts?

Changing states of matter and energy A block of ice is solid water. When heat (a form of energy) is added, the ice melts into liquid water. When heat is added, the snowflake melts and changes state to become liquid water. If heat is removed from water vapour, the gas cools down and it condenses back into liquid water.

Will the water overflow when the ice melts?

When the cube melts, the surrounding liquid can move into the space it filled. If the glass contains only ice and water, it will not overflow because the amount of extra water will be equal to that previously displaced by the cube(s).

How does ice caps melting affect us?

Polar vortexes, increased heat waves, and unpredictability of weather caused by ice loss are already causing significant damage to crops on which global food systems depend. This instability will continue to mean higher prices for you and growing crises for the world’s most vulnerable.

What is the main reason for melting of ice sheets Mcq?

What is the main reason for melting of ice sheets? Explanation: Global warming is affecting various places around the world. It is a accelerated the melting of ice sheets, permafrost and glaciers which there by causing rise in the average sea levels to greater extent continuously. 13.
