Question

question 10

fossil fuels consist of extracting decomposed organisms or plants that existed millions of years ago.

true
false

question 11

thermal energy (or heat energy) is related to the motion or vibration of molecules in a substance.

true
false

question 12

today we get most of our energy from:

biomass
renewable energy
nuclear
fossil fuels

Explanation:

Analyze Question 10

Fossil fuels are formed from the decomposed remains of ancient organic matter (plants and organisms) buried millions of years ago. Therefore, the statement is true.

Analyze Question 11

Thermal energy represents the internal kinetic energy of a system, which directly relates to the microscopic motion and vibration of its constituent atoms and molecules. Therefore, the statement is true.

Analyze Question 12

Globally, the majority of primary energy consumption is still derived from fossil fuels (coal, oil, and natural gas) rather than biomass, nuclear, or renewable sources. Therefore, the correct option is fossil fuels.
