What elements form Earth?
In the Earth's core iron makes up most of the mass. Everything else floats on the surface. The surface crust is mostly granite. The crust at the ocean bottom is mostly basalt.
Is the earth mostly land or water?
By mass, the Earth is composed of mostly iron (35 percent), oxygen (30 percent), silicon (15 percent), and magnesium (13 percent). The Earth's Surface is predominantly water!The surface area of the earth is predominantly water (about 70%), and I sincerely hope this isn't a serious question...The average depth of the oceans is only about 3000 meters (0,05 % of the radius of the Earth) so most of the mass of the earth is not water.To shorten this down....the earth is mostly water.
About 75 by mass of Earth's crust is composed of what two elements?
About 75 percent of the weight of the Earth's crust is made up of Oxygen and Silicon. The remaining percentage is composed of Aluminum, Iron, Calcium, Sodium, Potassium, and Magnesium.
Is earth matter?
Everything that has any mass at all is considered matter. This includes Jupiter. Even though the planet is made of gas, gas is still matter, so Jupiter is matter.
How much of earth mass is made up by the mantle?
The Mantle accounts for about 79% of the earths mass
What is the mass of the earth is made by which two elements?
In the Earth crust the most abundant are oxygen and silicon.
What elements form Earth?
In the Earth's core iron makes up most of the mass. Everything else floats on the surface. The surface crust is mostly granite. The crust at the ocean bottom is mostly basalt.
Is earth mostly gas or rocks?
Earth is made mostly of rock. It has comparatively small amounts of liquid and gaseous components. The four innermost planets of the Solar System have this in common with Earth, while the outer, non-dwarf planets are all gas giants, in which gaseous elements comprise the vast majority of the mass of the planets.
What part of earth's mass is made up of mostly silicate materials such as olivine?
Because oil does
What elements form?

What are the two most abundant elements by mass found in the earth's crust?
The two most abundant elements by mass in the earth's crust are oxygen and silicone. The crust of the earth typically runs between 20 and 25 miles deep from the surface.
Is the sun made mostly of hydrogen and helium true or false?
True. The Sun is mainly composed of hydrogen (about 74% of its mass) and helium (about 24% of its mass). The remaining 2% consists of trace amounts of heavier elements.
Is plutos gravity stronger than earths gravity?
The amount of gravity an object has is directly proportional to its mass. If you had 2 planets the same diameter as the Earth, one made mostly of hydrogen, the other, most lead, the Lead Earth would have much more mass, and therefore more gravity than the Hydrogen Earth. Now real planets are a milieu of many elements & compounds. One would have to find the average density of each planet, Earth & Pluto; then find their size, then calculate their masses. Assuming that most things are equal (both planets are mostly made of rock), the Earth is larger, and thus has more mass than Pluto. So Pluto's gravitational acceleration is a lot less than 9.8m/sec/sec (Earth's acceleration).
Is sunlight made up of elements?
No. Any kind of light is not made up of elements, but rather of photons, which have no rest mass.
What are the top 5 elements of the Earth by mass?
The mass of the Earth is approximately 5.98 × 1024 kg.It is composed mostly of iron (32.1%), oxygen(30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminum (1.4%); with the remaining 1.2% consisting of trace amounts of other elements. Due to mass segregation, the core region is believed to be primarily composed of iron (88.8%), with smaller amounts of nickel (5.8%), sulfur (4.5%), and less than 1% trace elements.
Why does the density of Saturn is much less than earth's even though it is much bigger in size?
Saturn is a planet made out of mostly gas. As gas has little mass, it is less dense than Earth. Remember that density is proportional to its mass and surface area.
How is a supernova related to matter found on earth?
A supernova is a star that explodes. Stars about the size of our Sun explode when they run out of "fuel". The fuel they have is Hydrogen which they fuse into Helium and thus convert mass into energy (they shine brightly), Then the Helium and some Hydrogen are fused into heavier elements (Lithium etc) making more energy. All elements heavier than Carbon and lighter than Iron are made in the supernova explosion that comes at the end of the star's "life". Heavier stars will make even heavier elements. The Earth is mostly made of these heavier elements. We are all stardust.
