Sea levels are rising due to melting ice and glaciers. Global warming is causing the Earth to warm up. This means sea levels are getting higher.
Sea Level Rise & Global Warming
Sea Level Rise: The increase in the average level of the ocean, caused by melting ice and glaciers, as well as thermal expansion of water due to global warming. Global Warming: The phenomenon of increasing average air temperatures near the surface of Earth over time. Thermal Expansion: The expansion of a substance when heated, causing it to take up more space.
Concepts:
Do you think sea level rise due to global warming is a serious problem?
- Yes, it is a very serious problem.
- No, it is not a serious problem.
- I'm not sure.
The world's oceans have risen 8 inches in the last century. By 2100, it is estimated that sea levels will rise between 1-4 feet. The melting of polar ice caps is one of the most visible effects of global warming.
