The answer "true" suggests that the farmers who created Providence Canyon indeed had poor farming practices. This implies that their farming methods were not effective or sustainable, leading to negative consequences such as erosion and the formation of the canyon.

Burning fossil fuels is the correct answer because it is a major source of pollution in the atmosphere. When fossil fuels such as coal, oil, and natural gas are burned for energy, they release harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants contribute to air pollution and have detrimental effects on human health and the environment. While pollen, forest fires, and volcanic eruptions can also contribute to air pollution, their impact is generally localized and not as significant as burning fossil fuels on a global scale.

Wood, leaves, and manure are all organic materials that can be used as fuel to generate energy. These materials come from living or recently living organisms, making them part of the biomass. Biomass fuels are considered renewable because they can be replenished through natural processes, such as the growth of plants and the decomposition of organic waste. Therefore, the correct answer for this question is biomass.

Washing your car in the middle of the day is not a way to conserve water because during that time, the sun is at its peak and the temperature is usually higher. This means that the water used for washing the car will evaporate quickly, resulting in wastage of water.

Tidal power depends on tides to generate electricity. Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans. As the tides rise and fall, the kinetic energy of the moving water can be harnessed to turn turbines and generate electricity. Unlike other renewable energy sources like wind or solar, tidal power is predictable and reliable, as tides occur twice a day without fail. Therefore, tides are the crucial factor in generating electricity from tidal power.

Geothermal energy refers to the heat energy stored beneath the Earth's surface. This intense heat can be harnessed to generate electricity or heat buildings. Unlike hydrogen power, nuclear fusion, and solar energy, which have different sources and processes, geothermal energy specifically utilizes the heat from the Earth's interior.

To prevent the dust bowl, farmers could have attempted all of the above soil conservation practices. Crop rotation involves planting different crops in a specific order to improve soil fertility and prevent erosion. Planting wind breaks, such as trees or shrubs, can help block strong winds and reduce soil erosion. Contour plowing involves plowing along the contours of the land, which helps to slow down water runoff and prevent soil erosion. By implementing all of these practices, farmers could have effectively conserved the soil and mitigated the dust bowl phenomenon.

Soil conservation refers to the management practices that are implemented to prevent the destruction or degradation of soil. This includes techniques such as contour plowing, terracing, and crop rotation, which help to prevent erosion and maintain soil fertility. By implementing these practices, soil can be protected from factors such as wind and water erosion, nutrient depletion, and loss of organic matter. Soil conservation is essential for sustainable agriculture and ensuring the long-term productivity of agricultural land.

The three major fossil fuels are coal, oil, and natural gas. While coal and oil are commonly known as fossil fuels, natural gas is also considered a fossil fuel as it is formed from the remains of ancient plants and animals that were buried and subjected to high pressure and heat over millions of years. Natural gas is a cleaner-burning fuel compared to coal and oil, and it is widely used for heating, cooking, and electricity generation.

The given correct answer states that fossil fuels are relatively inexpensive. This means that one advantage of using fossil fuels is their affordability compared to other sources of energy. While fossil fuels have several disadvantages such as being non-renewable, contributing to pollution, and eventually running out, their cost-effectiveness is not considered a disadvantage.

Nuclear power is advantageous because it is inexpensive to produce. Unlike other forms of energy, such as fossil fuels, the cost of nuclear power is relatively low once the initial investment in building the infrastructure is made. The fuel used in nuclear reactors, uranium, is also widely available and relatively cheap. This makes nuclear power an attractive option for countries looking to meet their energy needs without breaking the bank. Additionally, the cost stability of nuclear power allows for long-term planning and budgeting, making it a reliable and cost-effective source of energy.

Plowing removed the grass from the Great Plains, which had a significant impact when a drought struck in the 1930s. Without the grass to hold the soil in place, the exposed soil was vulnerable to erosion by wind. The combination of drought and strong winds led to massive dust storms, creating the infamous Dust Bowl. Therefore, plowing played a crucial role in causing the Dust Bowl.

In a nuclear power plant, water is changed into steam using the heat released from nuclear fission reactions. Nuclear fission involves splitting the nucleus of an atom, which releases a large amount of heat energy. This heat energy is used to heat water, which then turns into steam. The steam is used to drive turbines, which generate electricity. The burning of natural gas, geothermal energy, and captured solar energy are not used in the process of changing water into steam in a nuclear power plant.

Wind energy and hydroelectric power are both indirect sources of solar power because they are ultimately derived from the sun's energy. The sun powers the water cycle, which creates wind through the movement of air masses, and also drives the evaporation and precipitation that fills rivers and reservoirs, generating hydroelectric power. Therefore, both wind energy and hydroelectric power can be traced back to the sun's energy, making solar power the correct answer.

Wood is an example of a biomass fuel because it is derived from organic matter, specifically trees. Biomass fuels are renewable energy sources that come from living or recently living plant and animal materials.
