C. Greenhouse gases contribute to climate change
Explanation:
It is desirable to use an energy source that does not produce greenhouse gases because these gases contributes a whole lot to climate change.
Over the years, studies have shown that the primary use of fossil fuels have significant lead to changes in the climate.
- Greenhouse gases are produced during the combustion of fossil fuels.
- The most important gas produced in this process is the carbon dioxide.
- The greenhouse gases prevents long range radiation from leaving the earth.
- They waves interacts with the gases and warms the earth surface.
- Anomalous concentration of the gases causes more warming of the earth surface.
- This leads to a change in climate.

Answer:
When a disaster is declared, the Federal government, led by the Federal Emergency Management Agency (FEMA), responds at the request of, and in support of, States, Tribes, Territories, and Insular Areas and local jurisdictions impacted by a disaster.
Explanation:
Answer:
All steps are 20 * 100 (break the rest into appropriate pieces)
You can multiply as follows
(2000) * ((3 * 60) + (2 * 60) + 60)
V = 2000 * 6 * 60) = 720,000 cm^3 = .72 m^3
.72 m^3 * 2400 kg / m^3 = 1728 kg
Momentum (p) = mass × velocity
P= 200,000×4.5
P= 900,000 .... answer !!
4.2 liters..... there are 1,000 mL in a liter and there is a total of 4200 mL in this case which is divided by 1000 which gives you 4.2 liters.
