Question 7

Scientists are more than 95% certain that nearly all of global warming is caused by increasing concentrations of ___________ and other human-caused emissions.

Answer 7

greenhouse gases (GHGs)

Question 8

_________ is emitted during agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste. It can trap heat in the troposphere and deplete ozone in the stratosphere.

Answer 8

Nitrous oxide (N2O)

Question 9

Answer 11

Obliquity

Question 12

It is the point in the orbit of the earth closest to the sun.

Answer 12

Perihelion

Question 13

The ______________ or ______________ is an explanation for changes in the seasons which result from the changes in the earth’s orbit around the sun.

Answer 13

Milankovitch Cycles; Astronomical Theory of Climate Change

Question 14

it is where the direction of Earth’s axis of rotation is pointed

Answer 14

Precession

Question 15

It is the main driver of the greenhouse effect, and it enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products, and also as a result of certain chemical reactions (e.g., manufacture of cement). It is removed from the atmosphere (or “sequestered”) when it is absorbed by plants as part of the biological carbon cycle.

Answer 15

Carbon dioxide (CO2)
