What is biomas energy?

Biomass, a renewable energy source, is biological material from living, or recently living organisms, such as wood, waste, (hydrogen) gas, and alcohol fuels. Biomass is commonly plant matter grown to generate electricity or produce heat. In this sense, living biomass can also be included, as plants can also generate electricity while still alive. The most conventional way in which biomass is used however, still relies on direct incineration. Forest residues for example (such as dead trees, branches and tree stumps), yard clippings, wood chips and garbage are often used for this. However, biomass also includes plant or animal matter used for production of fibers or chemicals. Biomass may also include biodegradable wastes that can be burnt as fuel. It excludes such organic materials as fossil fuels, which have been transformed by geological processes into substances such as coal or petroleum.

What region on the earth near the equator receives the most solar energy?

The Atacama desert is on the equator and is above most clouds

rain forests and jungles receive little sunlight

mountains have few clouds

moisture and pollution obscure sunlight

What are people's basic needs?

People's basic needs include food, water, shelter, and warmth. In addition, humans need social connections, safety, and access to healthcare to thrive. Meeting these needs is essential for maintaining good physical and mental well-being.

How do worms behave?

Worms are typically nocturnal and burrow underground during the day to avoid predators and extreme temperatures. They feed on decaying organic matter in the soil, aiding in the decomposition process. Worms are beneficial to soil health as they help aerate the soil and improve its nutrient content through their castings.

What do you measure mass with in the metric system?

Mass is typically measured in the metric system using a scale or balance. The unit of measurement for mass in the metric system is the gram (g) or its multiples such as kilograms (kg) and milligrams (mg).

What is the difference of work and joule?

Work is a measure of energy transfer that occurs when a force is applied to an object and it moves in the direction of the force. Joule is the unit of measurement for work and energy, representing the amount of work done when a force of 1 newton is applied over a distance of 1 meter.

The concept of energy links the various scientific disciplines physical science life science and earth science explain why?

Energy is a fundamental concept that transcends scientific disciplines because it plays a critical role in all natural processes. In physical science, it is studied in the context of forces, motion, and thermodynamics. In life science, energy is essential for biological processes such as metabolism and cellular activities. In earth science, energy influences phenomena like weather patterns, climate change, and geological processes. By understanding energy, scientists can explain and predict interactions across diverse disciplines.

What is the starting energy in the sun?

The sun's primary source of energy is nuclear fusion, which converts hydrogen into helium. The core of the sun reaches temperatures of about 15 million degrees Celsius, where this fusion process occurs. This process releases an enormous amount of energy that powers the sun's brightness and heat.

The flow of energy in the biosphere is continually decreasing True or False?

False. The flow of energy in the biosphere is constant and not continually decreasing. Energy enters the biosphere in the form of sunlight and is continuously cycled through ecosystems via processes like photosynthesis and respiration.

How is natural gas found in the earth?

Methane gas at high pressure. Answer: Natural gas is one of the components of the production of fossil fuels (oil and coal) below ground. It collects in natural reserviors (porous rock formations capped with impervious rock). These formations are found by examining the underground stratigraphy by seismic exploration or the drilling of rock cores. Once a potential collection is identified it is confirmed by drilling a test well.

How do you get the formula mgh of potential energy?

The formula for potential energy, (mgh), comes from the equation (PE = mgh), where (PE) represents potential energy, (m) is mass, (g) is acceleration due to gravity, and (h) is height. This formula represents the energy an object possesses due to its position relative to a reference point.

Is mechanical energy a vector quality?

No, mechanical energy is a scalar quantity. It represents the sum of potential and kinetic energy in a system, without direction.

What kind of energy transformation happens in a waterfall?

In a waterfall, potential energy from the water at a higher elevation is converted into kinetic energy as the water falls downward. The kinetic energy can then be harnessed to generate electricity using hydroelectric power plants.

What does chemical energy geothermal energy?

Geothermal energy is the type of energy that comes from the heat that is within the earth. Chemical energy on the other hand refers to the potential energy of a chemical substance to undergo a chemical reaction.

How do countries generate electricity?

Electricity is generated by turning a turbine. There are many ways to power the turning of the turbine, including: 1) hydroelectric power (water flowing down by gravity via dams or other restrictions can turn turn turbines) 2) burning fossil fuels (coal, gas, oil) 3) nuclear power 4) wind 5) generating steam to turn the turbine (geothermal steam, or by burning fossil fuels or organics like wood or chemicals).

What is a example for chemical energy?

Chemical potential examples are like, Icy Hot ( the pain patch or cream ) or a Light Stick ( the ones you break/crack and the glow ) hope this helps a little :)

How deep does a home geothermal pipe have to be?

A geothermal pipe for a home generally needs to be buried at least 5-10 feet deep, but this can vary based on local regulations, soil type, and climate. Deeper depths may be required in colder climates to take advantage of more stable ground temperatures for efficient heat exchange.

The path of energy from the sun from one living thing to another is a?

The path of energy from the sun to living things is through photosynthesis, where plants convert sunlight into chemical energy. This energy is then passed on to organisms that consume plants, forming a food chain or web. Ultimately, energy is transferred between organisms as they eat and are eaten, with each step losing energy in the form of heat.

What is required by all living things?

Living things must be able to acquire nutrients and energy. This also means that living things must have a metabolism.

Is the energy stored in the feces lost to the ecosystem why or why not?

No, the energy stored in feces is not entirely lost to the ecosystem. Microorganisms in the soil break down feces, releasing nutrients back into the environment for use by plants and other organisms. This process helps in nutrient cycling and maintaining ecosystem health.

What type of cell is the most commonly used to convert solar energy into electricity?

Photovoltaic cells, commonly known as solar cells, are the most commonly used type of cell to convert solar energy into electricity. These cells absorb sunlight and generate direct current (DC) electricity through the photoelectric effect.

What is histiosis and monilla?

Histiosis is a rare form of cancer that arises from histiocytes, a type of immune cell. Monilla is a misspelling of the word "monilia," which refers to a type of yeast infection caused by the fungus Candida.

What is energy from heat called?

Energy from heat is typically referred to as thermal energy. Thermal energy results from the movement of atoms and molecules within a substance, leading to an increase in temperature.

The transfer of energy that occurs when molecules collide?

Conduction:The transfer of energy by collusions between the atoms and molecules in a material.

So conduction

But others think its heat because heats deffinition is

Heat: A transfer of energy from an object to another due to a difference in temperature.

What is the law of coversation of energy?

The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. In any closed system, the total amount of energy remains constant over time. This fundamental principle is a cornerstone of physics and plays a key role in understanding various physical processes.
