10. How many
forms of fossil fuels are there________________
a. One
b. Two
c. Three
d. Four
Explanation: There are three major forms of fossil fuels they are coal, oil and natural gas. They formed from organic remains of plants and animals that were converted into coal, oil and natural gas by exposure to heat and the pressure of the earth’s crust over millions of years.
11. According to WHO, how many premature deaths
annually linked to air pollution causing by the burning of fossil fuels?
a. One million
b. Three million
c. Five million
d. Seven million
Explanation: Fossil fuels are not environmental friendly. Burning of fossil fuels result in pollution and can cause serious environmental concerns. According to WHO, 7 million premature deaths annually linked to air pollution by the fossil fuels burning.
12. Energy in the form of heat and light is
obtained by________________
a. Biomass
b. Fossil fuels
c. Sun
d. Wind
Explanation: Energy in the form of heat and light is obtained by sun. Sunlight contains a large amount of energy. The Sun’s energy warms the planet’s surface, powering titanic transfers of heat and pressure in weather patterns and ocean currents.
13. SI unit
for energy is_____________
a. Watt
b. Kilogram
c. Newton
d. Joule
Explanation: SI unit for energy is joule. Metric unit of measurement for energy or work equal to a force of one Newton applied through a distance of one meter. One joule is equivalent to 0.737324 ft-lbs. Joule is a SI unit of work, energy and heat.
14. Trapped
heat inside the earth is known as_______________
a. Heat energy
b. Kinetic energy
c. Geothermal energy
