Front

What is the imaginary line that goes from the North Pole to the South Pole?

Back

Axis

Front

What do we call several months during the year that have similar temperatures?

Back

Season

Front

What can influence wind currents?

Back

Temperature difference between air over land and air over the ocean, temperature difference between air in the tropical zone and air in the polar zones, temperature difference between air close to the ground and air high up in the atmosphere.

Front

True or False: Scientists believe that we are currently living in a period of Earth's fifth ice age.

Back

True. Scientists believe that we are currently living in the warm period of Earth's fifth ice age, which began about 10,000 years ago. It is a warm period because glaciers are present but retreating.

Front

What do ice cores contain evidence of?

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term average weather patterns in a region.

What is the role of glaciers in Earth's climate system?

Back

Glaciers reflect sunlight, influence sea levels, and store freshwater.

Front

What is an ice age?

Back

A prolonged period of time when global temperatures are significantly lower, leading to the expansion of ice sheets and glaciers.

Front

What is the significance of studying ice cores?

Back

Ice cores provide valuable information about past climate conditions and atmospheric composition.
