How does the law of conservation of energy apply to the sun-Earth system?
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. In the sun-Earth system, energy from the sun is transferred to Earth in the form of sunlight. This energy is then used by Earth to power various processes such as photosynthesis and weather systems, while a portion is radiated back into space as heat. The total energy in the system remains constant due to this conservation principle.
What is closed energy?
here, ill copy from my school :) lol. im learning this too. hope this helps :DIn a closed systemClosed System: A system where the total mass is a conserved quantity but the total energy is not., energy can enter or leave the system but matter cannot.The planet Earth is an example of a closed system. The outer edge of the atmosphere acts as a boundary between the system, Earth, and its surroundings. Matter does not enter or leave the system, except for the occasional meteorite or shuttle, but energy is freely transferred between the Earth and its surroundings. Energy in the form of radiation from the Sun passes through the atmosphere to the Earth's surface. The Earth also emits radiation back out to space. Because energy passes across its atmosphere but matter usually does not, the Earth is considered a closed system.
What is the part of earth's system in which we live?
the biosphere bio meaning life rock and other such elements
How do matter and energy move through an atmosphere?
For living things to carry out their processes, energy must enter the earth system constantly.
What absorbed energy is reradiated some of which escapes into space?
The absorbed energy that is reradiated, some of which escapes into space, primarily refers to the Earth's thermal radiation. When the Earth absorbs sunlight, it warms up and subsequently emits infrared radiation. This process helps regulate the planet's temperature, but not all of this emitted energy remains trapped; a portion escapes into space, contributing to the balance of energy between the Earth and its atmosphere. This energy exchange is crucial for maintaining the Earth's climate system.
What is the significance of the gravitational binding energy of the Earth in relation to its overall stability and structure?
The gravitational binding energy of the Earth is important for maintaining its stability and structure. It represents the amount of energy needed to break apart the Earth due to its own gravity. A higher binding energy means the Earth is more stable and less likely to break apart. This energy helps hold the Earth together and maintain its shape and structure over time.
In terms of energy what kind of system is earth?
Earth is an open system when it comes to energy, as it receives energy in the form of sunlight from the sun and emits energy back out into space. This constant input of energy drives the Earth's climate, weather patterns, and sustains life on the planet.
What is the energy cycle?
The movement of energy into and out of the Earth system.
Is early earth an open or closed system?
Early Earth was an open system because energy and matter such as light energy and meteors were bombarding the Earth.
What are the two main sources of energy in earth's system?
The two main sources of energy in Earth's system are solar energy, which comes from the Sun, and geothermal energy, which comes from the Earth's internal heat.
How much energy would it take to destroy the Earth completely?
Destroying the Earth completely would require an immense amount of energy, estimated to be around 2.24 x 1032 joules. This energy would need to overcome the gravitational binding energy holding the Earth together.
Is earth an isolated system?
No. An isolated system is one which has no exchange of matter and energy with the surrounding. In case of earth, many gas particles of earth's atmosphere are lost to the space. Also it receives energy from the earth. Hence there is a transfer of matter and energy with surrounding (universe) so earth is not an isolated system.
What Is the meaning and significance of earths energy budget to life on earth?
The Earth's energy budget refers to the balance between the amount of energy coming into Earth from the sun and the amount of energy being emitted back into space. This balance is crucial for maintaining Earth's climate, weather patterns, and overall habitability for life. Understanding and monitoring the Earth's energy budget helps scientists assess the impact of human activities on the planet's energy balance and climate system.
Why is earth system resemble a closed system?
The state of the Earth's climate is dependent on the amount of energy stored by the entire system, and in particular the balance between the amount of energy Earth receives from the Sun, in the form of light and ultraviolet waves, and the amount of energy the Earth releases back to space, in the form of infrared heat energy.
What are the two source of energy for the earth system?
solar system and gas
Why scientist considers earth an essentially close system?
Earth is essentially not a closed system. It receives energy from the sun and looses energy as it radiates heat into space.
What is The Rotational Kinetic Energy of the Earth?
The rotational kinetic energy of the Earth is approximately 2.14 × 10^29 joules. This energy is a result of the Earth's rotation about its axis. It contributes to the overall energy balance of the Earth system.
