Honors Sea Levels Rising and Albedo

Front

What is albedo?

Back

Albedo is the measure of the reflectivity of a surface, expressed as a percentage. It indicates how much sunlight is reflected by a surface compared to how much is absorbed.

Front

Which surface has the highest albedo?

Back

Snow has the highest albedo, reflecting most of the sunlight that hits it.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What happens to particles when heat is added to a system?

Back

When heat is added, the particles in the system speed up due to increased energy.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where energy is passed from one molecule to another.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight, which can travel through a vacuum.

Front

How does temperature affect sea levels?

Back

As temperature increases, water expands, leading to rising sea levels.

Front

What is the relationship between albedo and climate change?

Back

Higher albedo surfaces reflect more sunlight, which can help cool the Earth, while lower albedo surfaces absorb more heat, contributing to warming.

Front

What is the effect of melting ice on sea levels?

Back

Melting ice contributes to rising sea levels as it adds more water to the oceans.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a substance due to an increase in temperature.
