1 answer

Here are the answers to your questions:

Question 1:
A) Earth's orbit alternates between a circular and an elliptical shape.
This is one of the three factors that influence the Milankovitch cycles.


Question 2:
A) Satellite measurements.
Satellites provide the most comprehensive data on ice loss near the poles.


Question 3:
A) Reducing emissions from cars.
This action directly contributes to reducing greenhouse gas emissions and can help mitigate global warming.


Question 4:
A) By burning fossil fuels off-site to make electricity that is used on-site.
Indirect emissions are those emitted in the production of energy that is consumed on-site.


Question 5:
A) The glass in a greenhouse is transparent to visible light and opaque to infrared wavelengths. The same can be said for greenhouse gases.
Greenhouse gases allow sunlight to enter but prevent some of the heat from leaving.


Question 6:
A) A gas composed of molecules with three oxygen atoms.
Ozone (O3) consists of three oxygen atoms.


Question 7:
A) Burning fossil fuels moves carbon from the geosphere to the atmosphere.
This is a critical process in the carbon cycle that adds carbon dioxide to the atmosphere.


Question 8:
A) Oceans moderate warming by absorbing carbon dioxide.
This ability helps to mitigate some effects of climate change.


Question 9:
A) The data obtained from ice cores.
Ice core data reveal past climate conditions and can provide insight into future climate change patterns.


Question 10:
A) Growing in a range farther north.
This shift can help Joshua trees adapt to changing climate conditions.
