Honors Sea Levels Rising and Albedo

Front

What is sea level rise?

Back

Sea level rise refers to the increase in the average level of the world's oceans due to factors such as melting ice, thermal expansion of water, and changes in land water storage.

Front

Which factors contribute to sea level rise?

Back

Factors include glaciers melting, ice sheets melting, thermal expansion of seawater, and changes in groundwater storage.

Front

What does NOT cause sea level rise?

Back

Sea ice melting does not cause sea level rise because it displaces the same amount of water as it contributes when it melts.

Front

Explain the concept of albedo.

Back

Albedo is the measure of how much sunlight is reflected by a surface. High albedo surfaces, like ice and snow, reflect most of the sunlight, while low albedo surfaces, like oceans, absorb more heat.

Front

Which surface has the highest albedo?

Back

Ice and snow have the highest albedo, reflecting most of the sunlight that hits them.

Front

What happens to sea levels when ice melts?

Back

When glaciers and ice sheets melt, they contribute additional water to the oceans, causing sea levels to rise.

Front

How does thermal expansion affect sea levels?

Back

As water warms, it expands, leading to an increase in sea level known as thermal expansion.

Front

What is the relationship between temperature and ice melting?

Back

As global temperatures increase, ice melts more rapidly, contributing to sea level rise and further warming due to decreased albedo.

Front

What is the impact of melting sea ice on sea levels?

Back

Melting sea ice does not raise sea levels because it is already floating and displaces its own weight in water.

Front

What is the expected effect on ocean levels if the volume of liquid expands?

Back

If the volume of liquid expands due to warming, sea levels are expected to rise.
