e. Trees and plants help to decrease levels of ozone in the atmosphere.
#1 [coal] sediment, rock and water apply pressure and heat, formed at the bottoms of swamps, oxygen cant reach the decaying matter
[oil] sediment, rock and water apply pressure and heat, formed at the bottom of oceans, oxygen cant reach the decaying matter
[natural gas] sediment, rock and water apply pressure and heat, formed at the bottom of oceans, oxygen cant reach the decaying matter, carbon bonds break to produce methane
#2 [crude oil] through drilling wells
[coal] through surface and underground mining
[natural gas] through drilling wells & through hydraulic fracturing
#3 C it was formed from ancient plants and animal remains
#4 C gases that contribute to smog decreased
#5 [coal] allowed companies to build more factories, allowed workers to build stronger buildings
[natural gas] decreased use of electric stoves
[petroleum] increased use of automobiles, allowed people to store and save food
#6 C. the availability of petroleum changed the way people store and package food
#7 C. solar energy because the dollar amount per kWh is lower
#8 A&B harmful to human health & protects earth from sun's rays
#9 B&E minimal environmental affects, doesn't produce pollutants
#10 [acquiring coal] can cause landslides & can cause sinkholes
[natural gas] can cause earthquakes
[both] release methane in the air & can contaminate ground water
#11 C less sea ice to reflect sun's rays
#12 [wind energy] uses groups of turbines
[solar energy] can be easily harnessed by homeowners
[hydropower] partly relies on the water cycle
[biomass] comes from organic plant and animal material
I just took the test its b and c
Are my answers correct??
thank you for the answer
everyone is correct, post all answers when finished
To determine which statements about ozone are true, let's analyze each option:
a. Most ground level ozone is released by vehicles.
To verify this statement, we need to investigate the primary sources of ground level ozone. While vehicle emissions do contribute to ground level ozone, they are not the primary source. Other sources include industrial emissions, power plants, and chemical solvents. Therefore, statement a is not entirely accurate.
b. Ozone is helpful for reducing smog levels.
To assess this statement, we need to understand the role of ozone in relation to smog. Ozone, a key component of smog, is not helpful for reducing smog levels. It is actually considered a pollutant and contributes to the formation of smog. Therefore, statement b is not true.
c. Ozone at ground level is harmful to human health.
To verify this statement, we need to examine the effects of ground level ozone on human health. Ground level ozone is harmful to human health and can cause respiratory problems, aggravate asthma, and trigger other respiratory conditions. Therefore, statement c is correct.
d. Ozone in the upper atmosphere protects Earth from the sun's rays.
To evaluate this statement, we must understand the role of ozone in the upper atmosphere. Ozone in the upper atmosphere, known as the ozone layer, provides a protective shield by absorbing most of the sun's ultraviolet (UV) radiation. This protects Earth from harmful UV rays. Therefore, statement d is true.
e. Trees and plants help to decrease levels of ozone in the atmosphere.
To determine whether this statement is true, we need to examine the role of trees and plants in relation to ozone. Trees and plants do not directly decrease levels of ozone in the atmosphere. However, they help reduce other air pollutants, which can indirectly contribute to the formation of ground-level ozone. Therefore, statement e is not entirely accurate.
In conclusion, the two correct statements about ozone are:
- Ozone at ground level is harmful to human health.
- Ozone in the upper atmosphere protects Earth from the sun's rays.
