What is the most abundant element in the core?
IronIron is the most abundant element by mass in the Earth constituting about 80% of the inner and outer cores of Earth. The molten outer core is about 8000 km in diameter and the solid inner core is about 2400 km in diameter.
What two kinds of matter were present in the nebula clouds that gave birth to the Earth?
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out but gravity can slowly begin to pull together clumps of dust and gas.
What was the solar nebula quizlet?
The solar nebula is the cloud of gas from which our solar system was born when it collapsed under its own gravity. By using the compositions of the Sun other stars and interstellar gas clouds we know that the solar nebula contained 98% hydrogen and helium and only 2% of all other elements combined.
What are three major features of our solar system that provide clues as to how it formed describe each one briefly?
Answer: Four major features provide clues: (1) The Sun planets and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto the planets divide clearly into two groups: terrestrial and jovian. (3) The solar system contains huge numbers of asteroids and comets.
What do both the terrestrial and jovian planets have in common quizlet?
Both the terrestrial and the Jovian planets possess a solid core made mostly of metallic and/or rocky material. The planets located closest to the Sun are smaller and have high density.
What were the three major components of the solar nebula quizlet?
hydrogen and helium gas hydrogen compounds rock metal. Hydrogen and helium gas were the most abundant by far comprising about 98% of the solar nebula.
What are the four major ingredients that make up the solar nebula?
Composition. The ingredients of the solar nebula fell into 4 categories based on their condensation temperatures: metals rocks hydrogen compounds (water methane ammonia) and light gasses (hydrogen and helium). Distance of a planet from the Sun determined the temperature and thus the materials which condensed first …
What is a solar nebula made of?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed possibly due to the shockwave of a nearby exploding star called a supernova. When this dust cloud collapsed it formed a solar nebula – a spinning swirling disk of material.
What are the two theories on how the solar system began?
These are the Nebular Hypothesis of Laplace the Planetesimal Hypothesis of Chamberlin and Moulton and the Capture Theory of See. Darwings theory of Tidal Friction is scarcely a distinct hypothesis but is mentioned separately on account of its application to all of the others.
What are the two lightest elements?
Hydrogen helium lithium and beryllium are the lightest four elements with one two three and four protons respectively. Hydrogen has no neutrons helium has two lithium has four and beryllium has five and the masses of the elements increase in that order.
What are three major features of our solar system that provide clues as to how it formed?
Four major features provide clues: (1) The Sun planets and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto the planets divide clearly into two groups: terrestrial and jovian. (3) The solar system contains huge numbers of asteroids and comets.

What are the two most abundant chemical elements in the universe?
Together helium and hydrogen make up 99.9 percent of known matter in the universe according to Encyclopedia.com.
Why are the Jovian planets formed from materials different from the terrestrial planets quizlet?
Why are the Jovian planets formed from materials different from the terrestrial planets? d. Gaseous Jovian planets formed farther away from the heat of the Sun are formed from light weight nebulae “dust.”
What processes cleared the nebula away and ended Planet building?
8) What process cleared the protoplanetary nebula away and ended planet building? Very likely the solar wind during the T-Tauri stage of the star clear the last of of the gas away or combined with ultraviolet radiation from other stars.
What is the elemental composition of the sun’s nebula?
Composition of the Solar Nebula The solar nebular contains 98% Hydrogen and Helium (produced in the Big Bang) and 2% everything else (heavy elements fusion products inside the stars). Local thermal environment (Temperature) determines what kind of material condensates.
What were the most abundant elements in the solar nebula?
Hydrogen is the most abundant element in the Universe helium is second.

What 2 things make up everything in the universe?
Everything in the universe is composed of two things: matter and energy.
What are two characteristics of terrestrial planets?
Terrestrial planets are Earth-like planets made up of rocks or metals with a hard surface. Terrestrial planets also have a molten heavy-metal core few moons and topological features such as valleys volcanoes and craters.
What elements make up planetary nebula?
Planetary nebulae usually contain larger proportions of elements such as carbon nitrogen and oxygen and these are recycled into the interstellar medium via these powerful winds.
What is Jupiter’s main ingredient?
Jupiter is made up predominantly of hydrogen. The simple basic gas a prime ingredient on the sun accounts for 90 percent of the atmosphere. Nearly 10 percent is composed of helium. A very small fraction of the atmosphere is made up of compounds such as ammonia sulfur methane and water vapor.
Different Types Of Nebulae
What were the three major components of the solar nebula?
Condensation of the Solar Nebula. The solar nebular contains 98% Hydrogen and Helium (produced in the Big Bang) and 2% everything else (heavy elements fusion products inside the stars).
Where did the elements in the Sun’s nebula come from?
The cloud was made largely of hydrogen (H) with some helium (He) and small amounts of the remaining naturally occurring chemical elements. The elements larger than He had to have been produced in a supernova.
What are the two types of nebulae?
On the basis of appearance nebulae can be divided into two broad classes: dark nebulae and bright nebulae. Dark nebulae appear as irregularly shaped black patches in the sky and blot out the light of the stars that lie beyond them.
Which two elements are found in most planets?
The most abundant elements among these objects are hydrogen and helium primarily because the sun and the four largest planets are predominantly made up of these two elements.
What were the two original elements in our universe?
The only chemical elements created at the beginning of our universe were hydrogen helium and lithium the three lightest atoms in the periodic table.
What are the three major components of the solar nebula?
The solar nebula like most things in the universe was 98% Hydrogen and Helium with small amounts of hydrogen compounds (1.4%) and traces of rock and heavy metals (0.6%). All elements heavier than Iron were created in supernova explosions of prior high-mass stars.
What is the most abundant element in the atmosphere?
Nitrogen
The most abundant naturally occurring gas is Nitrogen (N2) which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at . 93%.
What Is a Nebula?
What is the most important element in the universe?
Hydrogen is the most abundant element in the universe accounting for about 75 percent of its normal matter and was created in the Big Bang.
What are the two main types of planets in our solar system?
Planets are generally divided into two groups: the terrestrial and the giant planets. The terrestrial planets are the four inner planets: Mercury Venus Earth and Mars. They are generally small in size (about the size of the Earth) and are predominantly rocky in composition.
What differentiates terrestrial planets from Jovian planets?
The main atmosphere of terrestrial planets is a gaseous mix of carbon dioxide and nitrogen gases and all terrestrial planets have rocky surfaces. … Jovian planets are larger further from the sun rotate faster have more moons have more rings are less dense overall and have denser cores than terrestrial planets.
How terrestrial and jovian planets are formed?
Summary: The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The jovian planets formed outside what is called the frost line where temperatures were low enough for ice condensation. See also what is the national animal of honduras
What is nebula general composition?
Planetary nebulae are chemically enriched in elements produced by nuclear processing within the central star. Some are carbon-rich with twice as much carbon as oxygen while there is more oxygen than carbon in the Sun.
What are the characteristics of a solar nebula?
Four Major Characteristics of the Solar System
- smaller size and mass.
- higher density (rocks and metal)
- solid surface.
- few moons and rings.
- closer to the Sun.
