Which is true of solid biofuels?
Charcoal is the primary replacement when wood is scarce.
Indoor air pollution from them results in millions of deaths annually.
Switchgrass is a newly developed replacement for wood.
They are carbon neutral due to the net removal of forests.
The primary use of manure is as a heat source in developed nations.

Biodiesel
Ethanol
Carbon
a direct substitute for petroleum-based diesel fuel. It is usually more expensive than petroleum diesel, although the difference varies depending on market conditions and the price of petroleum.

Which of the following is NOT a solid biomass?
wood
charcoal

biodiesel
How is solid biomass primarily used?
To heat homes and for cooking food
as a substitute for petroleum
often mixed with gasoline to make a hybrid fuel
in developed countries by people who can afford it.
Which of the following statements BEST Describes the environmental effects of using solid biomass.
Solid biomass such as wood and manure produces large amounts of particulate matter, carbon dioxide, and nitrous oxides.
Solid Biomass burns cleaner than gasoline.
Solid Biomass can be combine with petroleum to create a biofuel that lasts longer and burns cleaner.
Solid Biomass is a fuel primarily used in developed countries because people can afford it.
Which of the following is NOT a negative consequence of the accumulation of sediments in reservoirs?
As reservoirs fill with sediments, less water can be impounded.
Sediment build up reduces the generating capacity and the lifespan of a dam.
A dam prevents nutrient-rich sediment from overflowing the river and fertilizing the low lying agricultural areas.
Sedimentation cannot be removed to reverse the excess siltation.
How are fossil fuels related to the sun?
All fossil fuels are created by decomposition of ancient plants and animals. Plants require sunlight to grow and animals require plants for food.
Fossil fuels are a result of the unequal heating of the earth's surface over millions of years.
The sun drives the hydroelectric cycle which helps to decompose waste material into coal.
Fossil fuels use heat from radioactive elements including uranium from the earth's interior.
