Renewable And Nonrenewable Energy Resources Quiz For Grade 5

Solar energy is produced by the sun. The sun emits radiation in the form of light and heat, which can be harnessed and converted into usable energy through various technologies such as solar panels. Solar energy is a renewable and sustainable source of power that can be used for electricity generation, heating, and other applications.

Tidal energy is produced by trapping rising tides. This is true because the force of the water from the rising tides is used to spin turbines, which in turn generate electricity. The movement of the water due to the tides provides a consistent and renewable source of energy that can be harnessed effectively.

Nuclear energy is considered very expensive, costing approximately $59.00 per pound. This high cost is due to various factors, including the construction and maintenance of nuclear power plants, the handling and disposal of radioactive waste, and the stringent safety measures required to prevent accidents or incidents. Additionally, the initial investment required to build nuclear power plants is substantial. These factors contribute to the overall high cost of nuclear energy compared to other forms of energy production.

The correct answer is 3,2,4,1. This order is based on the costs of the energy sources. Nuclear energy is typically the most expensive due to the high costs of building and maintaining nuclear power plants. Oil/gas energy is the second most expensive, as it requires extraction and refining processes. Coal energy is next in line, as it requires mining and processing. Biomass energy is the least expensive, as it can be derived from organic waste materials.

Biomass energy works by burning organic materials, such as wood, for fuel. This process releases heat, which can be used to generate electricity or produce heat for various applications. Burning wood for fuel is a common method of utilizing biomass energy as it is a renewable and readily available resource. Burning meat for fuel is not a typical method of biomass energy production, and burning unwanted leaves may be a form of waste management rather than energy generation. Therefore, the correct answer is by burning wood for fuel.

Coal has several disadvantages, all of which are mentioned in the answer choices. Firstly, coal is a major contributor to air pollution, releasing harmful pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter into the atmosphere. Additionally, setting up coal power plants can be expensive due to the infrastructure and equipment required. Burning coal also releases sulfur dioxide, which can lead to the formation of acid rain. Lastly, coal combustion emits large amounts of carbon dioxide, a greenhouse gas that contributes to global warming. Therefore, all of the above options accurately represent the disadvantages of using coal.

This statement is false because trees have the ability to reproduce and spread through seeds. They do not require human intervention for planting. Seeds from trees can be dispersed by various means such as wind, water, or animals, allowing them to grow and regenerate naturally without human assistance. Therefore, the statement that biomass is non-renewable energy if we didn't care about planting is incorrect.

Oil and gas energy, coal energy, and nuclear energy are all used to create heat energy. Additionally, they are all nonrenewable energy resources.

The correct answer is that non-continuous means that tides only run twice a day, solar energy can be affected by cloudy conditions, and wind energy may not always be available due to the absence of wind. This implies that these forms of energy are not consistently available and can be influenced by various factors such as time of day, weather conditions, and natural phenomena.

Wind, hydroelectric, tidal, and solar energy sources all have the common characteristic of being freely available in nature without any cost. Unlike other energy sources that require extraction or processing, these renewable sources harness natural elements such as wind, water, and sunlight to generate power. This makes them environmentally friendly and sustainable alternatives to fossil fuels, which have associated costs and limited availability.
