What is the source of the energy that powers the earth's system?

The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.

What is oceanic thermal energy?

Oceanic thermal energy refers to the energy derived from the temperature differences that exist between warmer surface waters and cooler deep waters in the ocean. This temperature gradient can be harnessed to generate electricity using technologies such as Ocean Thermal Energy Conversion (OTEC). By utilizing the temperature difference, OTEC systems can produce clean and renewable energy.

What energy from the internal heat of the earth?

Geothermal energy is the energy extracted from the internal heat of the Earth. This energy is harnessed by tapping into geothermal reservoirs deep underground to produce electricity or for direct use in heating and cooling systems. Geothermal energy is a sustainable and renewable source of power with minimal environmental impact.

Does a nuclear plant generates more energy than a geothermal plant?

Yes, a nuclear plant typically generates more energy than a geothermal plant. Nuclear plants use nuclear reactions to produce heat to generate electricity, while geothermal plants use the Earth's heat to generate electricity. Nuclear plants have a higher energy output due to the intense heat produced by nuclear reactions.

What will be the kinetic energy of the ram of a pile driver when it suddenly undergoes a 10-kJ decrease in potential energy?

10-kj will be added to the Kinetic Energy. Remember the law of conservation of energy. E=PE+KE. and Efinal = Einitial.

What is ecosystem With the help of the suitable models explain the energy flow in the ecosystem?

Ecosystem has two main components Biotic and Abiotic, which are independent of each other. Biotic components recive enrgy from abiotic component sunlight. This energy is further transferred from various strata in the Ecosystem which are based on the trophic system. It is teh structure that is based on dependence of one organism on another for teh nutrition purpose. The energy flows from basic producers to top level carnivores, and at the same time released into the atmosphere. The consumed energy is used to carry out various life functions.

How many geothermal power plants are there in the US?

The US has 77 geothermal power plants (2010 figures), leading the world with an installed capacity of 3086 megawatts (MW).

Most are in the Western states, with California the clear leader, with many power stations around The Geysers, north of San Francisco. Other notable states are Nevada, Idaho, New Mexico and Oregon.

How does ocean thermal energy work?

Therm means heat. Thermal energy is heat energy which has multipurposes, We obtain heat energy from sun which is very helpful for us in keeping ourself away from feeling cold in winter . That was one of the examples of your question

How does thermal energy transfer in the hydrologic cycle?

Thermal energy transfer in the hydrologic cycle occurs primarily through the processes of evaporation and condensation. When water evaporates from the surface of oceans, lakes, and rivers, it absorbs heat energy from the surroundings, cooling them down. As the water vapor rises and condenses to form clouds, this heat energy is released back into the atmosphere, influencing weather patterns and the overall climate.

Which contains a heavy atom often used in nuclear fission reactions to produce thermal energy?

Uranium-235 is a heavy atom commonly used in nuclear fission reactions to produce thermal energy. When uranium-235 absorbs a neutron, it becomes unstable and splits into smaller nuclei, releasing a large amount of energy in the form of heat, which is then used to generate electricity in nuclear power plants.

Where energy used by most organisms come from?

Most organisms get their energy from breaking down food molecules, such as glucose, through a process called cellular respiration. This process allows the cells to convert the energy stored in food molecules into a form of energy (ATP) that can be used for various cellular activities.

What is endicytosis?

Endocytosis is a cellular process in which cells absorb molecules or particles by engulfing them into the cell membrane and forming vesicles. It is a key mechanism for nutrient uptake, receptor recycling, and maintaining membrane homeostasis in cells. There are different types of endocytosis, such as phagocytosis, pinocytosis, and receptor-mediated endocytosis.

Is heat energy a kinetic energy or potenail energy and why?

Heat energy is a form of kinetic energy because heat is related to the motion of particles. This means heat is a form of kinetic energy. Adding heat energy to an object makes it hotter and causes its particles to move faster. That is why heat energy is a form of kinetic energy.

Answer

Heat is the name we give to energy in transit from a warmer body to a cooler body. So it's NOT a form of 'kinetic energy'; what the original answer defines is 'internal energy', not heat!

What providers the earth with all energy?

The sun is the primary source of energy for the Earth, providing sunlight that powers photosynthesis in plants, which in turn fuels most life on the planet. Other sources of energy on Earth include geothermal energy, tidal energy, and the Earth's internal heat.

What happens to the number of organisms as you move from the bottom of an energy pyramid to the top?

The number of organisms typically decreases as you move from the bottom to the top of an energy pyramid. This is because energy is lost at each trophic level through metabolic processes, so there is less energy available to support higher levels of consumers.

Which type of magnet is created from an electromagnet?

a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet

Do virus obtain and use energy?

Viruses do not have the cellular machinery to generate their own energy. Instead, they rely on the host cells they infect to provide the necessary energy and resources for their replication. Once inside a host cell, viruses hijack the cell's machinery to reproduce and create new viral particles.

What is the source of earths energy and what is called?

The primary source of Earth's energy is the sun. This energy is called solar energy, which is harnessed through various processes like photosynthesis, wind energy, and solar panels.

What are the advantages of natural gas energy?

Natural gas is a relatively clean-burning fossil fuel that produces lower levels of greenhouse gas emissions compared to other fossil fuels like coal and oil. It is also versatile and can be used for heating, electricity generation, and transportation. Natural gas is abundant and relatively inexpensive, making it a cost-effective energy source.

What useful energy comes out of a light bulb?

A light bulb emits light energy, which is useful for illuminating a space and providing visibility. Some light bulbs also produce heat energy, although this is often considered a byproduct rather than a primary source of useful energy.

How the human activities soil erosion?

People have been the main cause of worldwide erosion since early in the first millennium, said Bruce Wilkinson, a U-M professor of geological sciences. Wilkinson will present his findings Nov. 8 at a meeting of the Geological Society of America in Denver, Colo.

Many researchers have tried to assess the impact of human activity on soil loss, but most have only guessed at how erosion due to natural forces such as glaciers and rivers compares with that caused by human activity---mainly agriculture and construction, Wilkinson said. He used existing data on sedimentary rock distributions and abundances to calculate rates of natural erosion.

"If you ask how fast erosion takes place over geologic time---say over the last 500 million years---on average, you get about 60 feet every million years," Wilkinson said. In those parts of the United States where soil is being eroded by human agricultural activity, however, the rate averages around 1,500 feet per million years, and rates are even higher in other parts of the world. Natural processes operate over areas larger than those affected by agriculture and construction, but even taking that into account, "the bottom line is, we move about 10 times as much sediment as all natural processes put together," he said.

Because soil formation proceeds at about the same rate as natural erosion, Wilkinson's results mean that humans are stripping soil from the surface of the Earth far faster than nature can replace it

Is rocks a conductive?

Most rocks are poor conductors of electricity due to their high resistance. However, certain types of rocks containing minerals like metal ores or metal oxides can exhibit some level of conductivity.

What are three sports in which a force changes the velocity of a person?

  1. Basketball - Players exert a force when dribbling, passing, or shooting the ball, which changes the ball's velocity.
  2. Swimming - Swimmers exert force against the water to propel themselves forward, changing their velocity in the pool.
  3. Football - Players exert force when kicking or throwing the ball, resulting in a change in the ball's velocity.

Does fireworks have kinetic energy?

Yes, fireworks have kinetic energy when they are being propelled into the air or when they are in motion. However, once they explode and release their energy in the form of heat, light, and sound, their kinetic energy is transformed into other forms of energy.

What is more likely to happen when mitochondria malfunction?

When mitochondria malfunction, there can be a decrease in energy production, leading to cellular damage and even cell death. This can result in various health problems such as neurodegenerative diseases, metabolic disorders, and muscle weakness.
