Which of the statements is correct about solar energy?

The correct statement about solar energy is that it is an abundant, renewable source of energy. Solar energy is generated from the sun, which is an unlimited source of radiation. Solar energy is a clean and sustainable energy source, meaning it does not produce any pollutants which are harmful to the environment.

Additionally, it is a renewable source of energy since the sun does not run out of energy, making it a viable energy source for the long-term future. Solar energy can be used to generate both electricity and heat.

Electricity is generated through photovoltaic cells, which convert the sun’s energy into electricity. Solar thermal systems are also used to generate heat, which can be used to heat buildings, produce hot water, or power HVAC systems.

Solar energy is an attractive energy source because it is free and can be used virtually anywhere in the world.

Which of the following statements relating to solar system is are correct?

A) The solar system is made up of the sun, eight major planets and a number of smaller objects like asteroids and comets

B) The solar system has no moons

A) The statement that the solar system is made up of the sun, eight major planets and a number of smaller objects like asteroids and comets is correct. The eight major planets in the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The asteroid belt is located between the orbits of Mars and Jupiter, and the Kuiper belt is located beyond the orbit of Neptune. There are also many comets and other small objects in the solar system.

B) The statement that the solar system has no moons is incorrect. In fact, the solar system has dozens of moons. For example, Earth has one large moon, while Jupiter has 79. Saturn also has many moons, including the iconic Titan, noted for its large rivers and lakes filled with methane and ethane.

Other planets in the solar system, such as Mars and Neptune, also have their own moons.

Which of these statements about wind power is false?

Wind power does not produce pollution.

The statement that “Wind power does not produce pollution” is false. Although, wind power is a clean, renewable source of energy that does not emit air pollutants or greenhouse gases, the energy production from wind power does produce some form of pollution.

For example, during the manufacturing process of wind turbines, air pollution is created when certain metals are burned or when certain parts are produced using hazardous materials. Moreover, environmental concerns have been raised about the impact of wind turbine noise on wildlife and humans.

Additionally, bird deaths due to collision with wind turbines have also been documented and are considered a form of pollution.

Which is not true of wind?

Wind is not a form of renewable energy sources. Wind, along with other forms of renewable energy such as solar, hydropower, and geothermal, are sources of clean, renewable energy that are becoming increasingly popular due to reducing dependence on fossil fuels and potentially reducing the impact of climate change.

Wind, however, has low energy density, and so is not considered to be a particularly efficient source of power compared to other renewable energy sources, and therefore is not used as much.

Is wind energy a non-renewable resources?

No, wind energy is not a non-renewable resource. Wind energy is a renewable resource because it is generated from the natural motion of the wind, which is an unlimited resource. Wind turbines convert the kinetic energy of the wind into mechanical power, which is then converted into electricity.

This process does not deplete any finite resource, making it an excellent, sustainable, and renewable source of energy. Additionally, wind energy does not release harmful emissions when it is generated, making it one of the cleanest sources of energy available.

Furthermore, the technology used to harness wind power is constantly advancing and improving, making wind energy increasingly efficient and cost effective.

Are non-renewable resources True or false?

Non-renewable resources are resources that cannot be replaced or replenished in a short period of time. Therefore, the answer to this question is “True”. Non-renewable resources include fossil fuels such as oil and gas, minerals, and ore bodies that have been formed over millions of years and cannot be replenished.

Many of these resources are used in energy production and manufacturing, and the finite nature of these resources means that they must be used thoughtfully and managed carefully to ensure that their supply does not run out.

As such, non-renewable resources are critical for many aspects of everyday life, and must be carefully managed for future generations to benefit.

What are the 4 types of non-renewable energy?

The four types of non-renewable energy are fossil fuels, nuclear energy, geothermal energy, and solar energy.

Fossil fuels, such as coal, oil, and natural gas, are created over millions of years by the remains of plants and animals compressing and decomposing underground. They are a non-renewable energy source because they are finite and their extraction and burning releases greenhouse gases into the atmosphere.

Nuclear energy is created from natural elements like uranium and thorium. Nuclear reactions in nuclear power plants generate large amounts of energy from small amounts of fuel. However, the process of extracting energy from nuclei has the potential to cause radioactive contamination of the environment.

Geothermal energy is generated from the heat inside the Earth. Heat is extracted from underground reservoirs, hot springs, and volcanoes, which can be used to produce electricity. Although this type of energy is very clean and efficient, its availability is limited to certain geographic locations.

Solar energy is a non-renewable energy source. Solar energy is generated by capturing and converting rays from the sun into electricity with photovoltaic panels or concentrating solar power systems. Solar energy is abundant, but the technology to capture it is still expensive and energy production is discontinuous, meaning it is intermittent and cannot provide a continuous supply of electricity.

How is wind energy produced?

Wind energy is produced by using the kinetic energy of the wind to drive a turbine. This turbine is then connected to an electrical generator, which takes the mechanical power produced by the turbine and converts it into electrical energy.

The wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. This electricity is sent through transmission and distribution lines to homes and businesses.

Wind energy systems can be ground-mounted or located on towers or buildings. Wind turbines typically range in size, but modern wind turbines are usually around 100-300 feet tall. The size of the turbine and the height of the tower both affect the amount of electricity that can be generated.

Wind energy is a clean, renewable energy source that can be used to power homes, businesses, and even entire communities. Furthermore, it is one of the most cost-effective energy sources available. In addition to this, wind energy produces no air or water pollution, doesn’t require fuel, and emits no greenhouse gases.

What is meant by natural resources explain renewable and non-renewable natural resources?

Natural resources are materials or elements found in nature that can be used for economic production. These materials provide economic benefit to humans and are essential for survival, development, and providing for human needs.

Natural resources can be divided into renewable and non-renewable resources.

Renewable resources are those which can be replenished naturally, such as sunlight, air, water, and soil. Renewable resources are considered to be the most sustainable source of energy, and have the potential to supply a much higher proportion of global energy than they currently do.

For example, solar power, wind power, and hydropower are a few of the renewable energy sources being used to generate power.

Non-renewable resources are those which are exhaustible and can be consumed much faster than they can be replenished. Fossil fuels, primarily oil, gas, and coal, are some of the most extensively used non-renewable resources.

Since they are finite and limited, they are considered to be unsustainable sources of energy in the long-term. Non-renewable resources are considered to be one of the major environmental problems of our time due to their contribution to air, soil, and water pollution.

Is gas a renewable energy?

No, gas is not considered to be a renewable energy source. Renewable energy is defined as energy sources that can be replenished naturally and continuously over a short period. Gas, on the other hand, is a finite resource derived from natural underground deposits that cannot be replenished in a short period of time, and is therefore considered a non-renewable energy source.

Although it is more environmentally friendly than more traditional energy sources such as coal and oil, gas is still a fossil fuel. As such, burning gas can still release greenhouse gases into the atmosphere, leading to climate change and other environmental concerns.

Can water be renewable?

Yes, water can be renewable. This is because it can be found naturally in large bodies, such as oceans and lakes, and can also be sourced from the atmosphere through precipitation and the water cycle.

It is stored in reservoirs, filter systems, and aquifers and can be used again and again. It can also be replenished by natural processes, such as the infiltration of water into groundwater, the melting of ice sheets, or the addition of rain to rivers, lakes, and reservoirs.

As such, it is possible to utilize renewable sources of water that is fit for consumption, agriculture, industrial processes, and cooling. In addition, water can also be employed for energy generation, such as through hydropower, which further adds to its potential as a renewable resource.
