Quiz about Glaciers, Albedo, and Feedback Loops

Question 1

Albedo is how reflective a surface is

Accepted Answer

TRUE

Answer

FALSE

Question 2

Surfaces with a HIGH albedo absorb a lot of solar energy

Accepted Answer

FALSE

Answer

TRUE

Question 3

Surfaces with a HIGH albedo reflect a lot of solar energy

Accepted Answer

TRUE

Answer

FALSE

Question 4

The level of albedo is dependent on color of the surface

Accepted Answer

TRUE

Answer

FALSE

Question 5

Surfaces with a high albedo will get very hot in the Sun

Accepted Answer

FALSE

Answer

TRUE

Question 6

Surfaces with a high albedo have a numerical value close to 1

Accepted Answer

TRUE

Answer

FALSE

Question 7

A feedback loop has features that do NOT affect one another at all

Accepted Answer

FALSE

Answer

TRUE

Question 8

A POSITIVE feedback loop amplifies/magnifies the effect

Accepted Answer

TRUE

Answer

FALSE

Question 9

A NEGATIVE feedback loop amplifies/magnifies the effect

Accepted Answer

FALSE

Answer

TRUE

Question 10

As temperatures warm, glaciers melt, this decreases albedo, which increases temperatures further... this is an example of a positive feedback loop

Accepted Answer

TRUE

Answer

FALSE

Question 11

When you eat a meal the glucose level in your blood increases, your body then makes insulin, which removes excess glucose from your blood stream, bringing your glucose levels back down to a normal range... this is an example of a positive feedback loop

Accepted Answer

FALSE

Answer

TRUE

Question 12

Temperatures must be below freezing at all times in order for glaciers to exist in an area

Accepted Answer

FALSE

Answer

TRUE

Question 13

Enough snowfall is one of the main factors that contributes to an area having glaciers

Accepted Answer

TRUE

Answer

FALSE

Question 14

The number of glaciers in Glacier National Park has remained the same for the last several decades

Accepted Answer

FALSE

Answer

TRUE

Question 15

While Glacier National Park does have glaciers, remote regions in Russia that record some of the coldest temperatures ever seen do not have glaciers

Accepted Answer

TRUE

Answer

FALSE

Question 16

Glaciers completely melt and reform every year

Accepted Answer

FALSE

Answer

TRUE

Question 17

Glaciers can partially melt and change in size with the seasons, but they do not completely melt every year

Accepted Answer

TRUE

Answer

FALSE

Question 18

The amount of solar energy that an object absorbs has no effect on its temperature

Accepted Answer

FALSE

Answer

TRUE
