Energy
The Energy category covers the description, definition, and use of all types of energy. Questions of a general nature can be put in the general Energy category. Other sub-categories exist for Fossil fuels, Nuclear energy, and renewables such as Wind, Solar, Hydro, Tidal, and Wave power.

Why do scientists consider earth and essentially closed system?
Because not much matter gets in or out. However, please note that if you include energy in your considerations, it is notclosed, since energy is flowing in and out all the time.

Total amount of energy an object has?
The total amount of energy an object has is its sum of kinetic energy (energy of motion) and potential energy (stored energy). This can be calculated using the equation: total energy = kinetic energy + potential energy.
Does earth receive its energy from the sun?
Yes, Earth receives its energy from the sun through a process called solar radiation. Solar energy is essential for heating the Earth's surface, driving weather patterns, and sustaining life through photosynthesis.
Example of law conservation of energy?
Let's say that everything is an example of the Law of Conservation of Energy - because this is a law that has never been seen to fail. More specifically, in any energy conversion, one type of energy gets reduced; another type of energy inreases in the same amount.
The hydrologic rock and tectonic cycles are powered by two main energy sources what are the called?
The hydrologic cycle is powered by solar energy, which drives evaporation and precipitation. The tectonic cycle is powered by heat from the Earth's interior, which drives plate tectonics and volcanic activity.
How is energy moved from one organism to another?
How is energy moved from one organism to another?
A.when one organism chases another organism, energy is movedB.when one organism is close by another organism, energy is movedC.when one organism touches another organism, energy is movedD.when one organism eats another organism, energy is moved
Where does the energy come from to melt ice?
Usually from the surrounding air, meaning that while the ice melts, the surrounding air will cool down. Or water, if the ice is in water.

Is geothermal energy available almost everywhere?
Geothermal energy is available everywhere - with there being varying levels of difficulty and expense in making use of it. By this I mean that besides doing it near tectonic plates, or doing some very expensive drilling, it is still impractical in many areas.
However, technology keeps advancing, and we can already make more use of it than in the past. One day we may draw quite heavily upon it. And will no doubt need to!
What happens when the earths atmosphere traps energy from the sun?
When the Earth's atmosphere traps energy from the sun, it leads to an increase in temperature on the planet. This is known as the greenhouse effect, where certain gases in the atmosphere, like carbon dioxide and methane, trap heat and prevent it from escaping into space. This phenomenon is essential for keeping Earth at a habitable temperature but has been accelerated by human activities, leading to global warming.
Compare the climate today with it during the ice age?
During the ice age, the Earth was much colder with extensive ice sheets covering large parts of the planet. Today, the climate is warmer due to factors such as human-induced greenhouse gas emissions, resulting in overall global warming and more extreme weather events. The ice age period had lower sea levels and different vegetation patterns compared to today's climate.
What is a glowing region in the atmosphere?
A glowing region in the atmosphere could refer to phenomena such as the auroras (Northern and Southern Lights) caused by the interaction of solar wind with the Earth's magnetic field. It may also refer to noctilucent clouds, high-altitude clouds that can appear to glow in the twilight sky due to their altitude and the way they scatter sunlight.
How does energy cause damage on Earth?
Energy can cause damage on Earth through processes like burning fossil fuels, leading to air pollution and climate change. Overconsumption of energy sources can also deplete natural resources and disrupt ecosystems, impacting biodiversity and disrupting natural balance. Additionally, the extraction and production of energy sources can lead to habitat destruction and pollution of land and water.
What are the molecules that bump into one another cause energy called what?
The molecules that bump into one another and cause energy are called reactants. When reactant molecules collide with enough energy, they can undergo a chemical reaction and transform into products. This collision energy is known as activation energy.
How does kinetic energy affect your life?
Kinetic energy is the energy an object possesses due to its motion. In daily life, kinetic energy plays a role in activities such as walking, driving a car, or playing sports. Understanding kinetic energy helps in calculating the speed and impact of moving objects, which is important for safety in various situations.
What is the difference between opaque and translucent?
OPAQUE means light transmission is blocked; essentially zero light transmission. A steel plate is opaque. A black piece of cardboard is opaque.
TRANSLUCENT means some light gets through but it is scattered in passage so images do not get through. A frosted glass sheet is translucent. Shower curtains are often translucent.
What is rapidly returned to the atmospheric reservoir when humans burn fuels?
Carbon dioxide (CO2) is rapidly returned to the atmospheric reservoir when humans burn fuels. This process contributes to the greenhouse effect and global warming by increasing the concentration of CO2 in the atmosphere.
Electrical energy travels from a power station through what kind of source?
You answer the question because I dont know!
Which of these is a renewable energy source coal wind natural gas or oil?
Wind is a renewable energy source because it relies on the power of wind to generate electricity. Coal, natural gas, and oil are all non-renewable sources of energy because they are finite resources that can be depleted over time and are not easily replenished.
What is so good about geothermal energy?
Geothermal energy is considered good because it is a renewable energy source that produces low emissions, provides a consistent baseload power supply, and can be used for heating and cooling purposes as well. It is considered environmentally friendly and reliable compared to fossil fuels.
Where does the energy from solar wind hydroelectric sources originally come from?
As you will know energy can not be created. Only transferred from one thing from another. Solar energy captures energy from the sun. Wind energy gets it from the kinetic energy making it move. And hydro electric also gets from kinetic energy. But kinetic energy from the movement of the waves.
What separates a chemical reaction from a nuclear reaction?
In a nuclear reaction, the nucleus of an atom undergoes a change. Common examples would be alpha decay, beta decay, fusion, and fusion. In each of those cases, different elements are formed in the process. This never happens in ordinary chemical reactions. In chemical reactions, it is the electrons that are involved , not the nucleus of the atom.
A closed system or a closed environment can support only as many organisms as the available energy, minerals, and oxygen will allow. In a closed system, there is a limited amount of resources available, so the population of organisms will stabilize based on these factors.
Is the energy stored in food heat energy?
Energy is stored in many ways. Energy is stored in food. We eat the food to get energy. Energy can also be stored in other ways, such as batteries.
Sources of stored energy take many forms like food, fuel and batteries. All energy on the Earth comes from the Sun.
Heat from the sun warms everything on the Earth. Light and heat are forms of energy, which come directly from the Sun. Plants, use the energy from sunlight to make food. Energy from the sun is stored in leaves, stems, roots and fruits. When an animal eats plants it gets the energy stored inside the plant.
Animals eat plants and get the energy stored in plant tissues. They utilize this energy for various activities like running, climbing, hunting and keeping warm. Food we eat contains energy to power our bodies.
Fuels such as oil and coal contain huge amounts of energy. Energy released from these fuels, wind and water can be changed into electricity. Energy is needed for almost all activities that make up our lives.
thank u . . :-)True or false An energy-releasing process that does not require oxygen is replication?
False. Replication is the process by which DNA is copied, and it does not release energy. An energy-releasing process that does not require oxygen is glycolysis.
