Unit 5 - Weather vs. Climate & Long-term climate change

The climate of a location can be described by its:

• Average air temperature

• Humidity

• Timing and amount of percipitation

• All of the above

The long term average weather for an area is called

The climate for a particular place changes very

• Fast

• Slowly

• Moderately

• Often

The temporary state of the atmosphere in the region is known as climate.

• True

• False

Compared to climate, weather is

• Not important

• Variable

• Guarenteed

• Easy to predict

By analyzing ice cores, scientists have a record of conditions dating back how many years?

• 800

• 8,000

• 80,000

• 800,000

How do ice cores in Antarctica tell us about the past?

• It is so cold that snow doesn't melt, all years of snow pile up and compresses and is preserved in the ice core.

• The snow falls then melts and re-freezes creating ice that can be studied.

• The wind blows snow into certain locations where it collects and can be analyzed.

The layers of an ice core are like

• Layers of an onion that can be peeled apart.

• Sheets of paper stacked very tall.

• Tree rings representing a new layer of snow for each year.

What information can be extracted from an ice core? Check all that apply.

• The temperature at the time the snow fell.

• How much dust was in the air at the time the snow fell.

• How much CO2 was in the atmosphere at the time the snow fell.

What is the name of the Antarctic lake where scientists drilled 2.2 miles of ice core?

• Varykino

• Vostok

• Veewok

• Vulcan
