Elements are defined by their atomic nucleus, the core of the atom, consisting of neutral neutrons and positive protons. The thing that makes two elements different is the number of protons. For example Hydrogen has 1 proton, Oxygen has 8 and Gold has 79. If you have two elements with different numbers of neutrons, they are called isotopes of that element. In principle you can create a new element by smashing together a bunch of protons to create a nucleus, but some combinations are much more stable than others. Therefore the vast, majority of the matter in the universe consists of the first 92 elements of the Periodic Table (after Uranium, which has 92 protons and is therefore element number 92, they are all radioactive and no higher numbered element occurs naturally on Earth). Most of that matter again consists of Hydrogen with one proton (ca. 75%) and Helium with two (ca. 23%) with all other elements sharing the remaining 2%.
Earth is composed of various elements and materials, but most of the matter is found in the core, mantle, and crust. The total mass of Earth is estimated to be around 5.97 x 10^24 kilograms.
there are four the, names are solid,liquid,gas and the new one is plasma.
The mass of the Earth is about 5.97 x 10**(24) kg. [where ** means 'to the power of']

How much matter is recycled on earth?
The amount of matter that is recycled on Earth is not easily quantifiable due to the complex and interconnected nature of Earth's ecosystems. However, it is estimated that a significant amount of matter is recycled through processes like decomposition, nutrient cycling, and waste breakdown to sustain life on the planet. Recycling of matter is essential for maintaining the balance and health of Earth's ecosystems.
Is earth matter?
Yes, Earth is made up of various types of matter. It consists of solids, liquids, and gases that make up the planet's structure, atmosphere, and surface features. Earth's matter includes elements like carbon, oxygen, silicon, and more.
What type of system is the Earth considered in terms of matter?
The Earth is considered a closed system in terms of matter, meaning that matter does not enter or leave the Earth on a significant scale. While small amounts of matter may enter or exit the Earth's atmosphere, the overall mass of the planet remains relatively constant.
Why do scientists consider earth and essentially closed system?
Scientists consider Earth to be an essentially closed system because while matter on Earth can enter and leave in the form of gases, meteorites, and space debris, the overall amount of matter remains constant. This means that Earth's resources are finite and must be managed sustainably to maintain the planet's stability for future generations.
Explain why the Earth is essentially a closed system in terms of matter and if it also a?
The Earth is essentially a closed system in terms of matter because very little matter enters or leaves it. While energy from the sun does enter the Earth, matter such as air, water, and rocks primarily remain on the planet. However, the Earth is not a closed system when considering energy because it receives energy from the sun and releases energy back into space.
What is one of the questions that chapter 3 of Alan Weisman's The World Without Us tries to answer?
How much does our presence on earth matter?
Why are neutron stars made out of different matter than earth?
Neutron stars are made of the same matter as Earth, but they have so much mass that their matter has a high density and the atoms have been crushed with everything compressed into neutrons.
Where would you have less matter earth or the moon?
The Earth has more matter than the moon. The Earth has a much larger mass and volume, containing a diverse range of elements and compounds. In comparison, the moon has a much smaller mass and volume, primarily composed of rock and dust.
Would 1 kg of lead and earth be bigger then marshmallows and earth?
No, it wouldn't. Eath is much larger no matter how many kg of lead there is. Mashmallows are much too small. Earth is very big.

What are the two important elements of psychology?
Water and fire, earth and air just don't matter as much.
Dust matter or not?
everything on earth is matter
What is the state of matter in the earth's crust?
the state of matter for the earth's crust is continental and oceanic.
Is gravity produced by earth matter?
Gravity is produced by all matter, including that of Earth.
Which state of matter is the earth's crust?
The state of matter the Earth's crust is in is solid.
What is matter cycles?
This used and reused of matter on earth is called the "matter cycle".
What percent of earth's living matter is carbon?
Roughly 50% of Earth's living matter is composed of carbon.
