Océanos en expansión

The video explains global warming and its effects, such as ice melting and rising sea levels. Scientists initially miscalculated sea level rise due to not considering thermal expansion, which accounts for over 50% of the increase. If unchecked, rising sea levels could lead to severe flooding in low-lying areas, highlighting the importance of addressing global warming.

What is one of the primary effects of global warming on the polar regions?

• Formation of new ice caps

• Decrease in ocean salinity

• Melting of large amounts of ice

• Increased snowfall

Why did scientists initially miscalculate the rise in sea levels?

• They overestimated the amount of ice melting

• They underestimated the amount of rainfall

• They did not account for thermal expansion

• They ignored the effects of ocean currents

What happens to water molecules as temperatures increase?

• They move away from each other

• They move closer together

• They form ice crystals

• They remain stationary

What percentage of sea level rise is attributed to thermal expansion?

• Exactly 75%

• More than 50%

• About 25%

• Less than 10%

What is a potential consequence of continued sea level rise?

• Increased mountain formation

• Severe flooding in low-lying areas

• Decrease in global temperatures

• Expansion of deserts
