The earth does get bigger! Every time a meteorite hits the earth, or even if it burns up in the atmosphere, the "mass" of that meteorite adds to the mass of the earth. Simply put, mass is weigh and material. Rocks however don't add too much mass to the earth. Rocks are formed from lava (igneous rocks) or from part of the earth's crust (sedimentary rocks). They don't add any weight to the earth because when the weight of the rocks is added to the weight of the rest of the earth, the total weight is the same as it was before the rocks were formed. I believe your question has more to do with size. In other words, if more and more rocks are being formed on the outside of the earth, why doesn't the earth get bigger? The answer is similar. The rocks that are formed on the outside of the earth come from the inside of the earth. Therefore, when rocks are formed on the outside of the earth, they leave empty spaces inside the earth. In reality, the
"empty space inside" that I mentioned could be very small and is not deep in the earth's crust. The empty spaces won't make the earth fall in on itself all of the time. If water from under the earth's crust are carried away, however, sinkholes can form. Much more mass needs to be added to the earth until the earth can become noticeably bigger

What force is needed when forming sedimentary rocks?
Geo-thermal force is needed in forming the sedimentary rocks. The fragments of igneous rocks by erosion are carried by water currents and deposited in the basin for millions of years. The upheaval in the earth strata bring these deposits deep. The pressure of earth mass and its heat converts these deposits in to sedimentary rocks. The red sand stone is the best example of sedimentary rock formation.
Why vesicular texture is not associated with peridotites?
Peridotites are invasive rocks formed underneath the earth's surface and the high pressure conditions dodge gases from forming and getting away
What caused the earth to continue to grow in size?
As the lava cools its makes rocks..... then it become part of the land and grows bigger as there is more lava
What are rocks that hit the earth?
meteorites are rocks that hit the earth meteors have not
The smallest group of rock forming minerals consists of silicates?
Rock-forming minerals 1. Silicates - are minerals which consist of silicon and oxygen with some metals or nonmetals. Some rocks which have these minerals are granite, sandstone, basalt, gneiss and quartzite. 2. Carbonates - are minerals which consist of carbon, oxygen and some other elements. Rocks in which these minerals are found include marble, limestone and dolomite. 3. Oxides - are minerals which consist of oxygen and some other elements. They are found in rocks such as sandstone and shale. Although there are about 3000 different minerals found on Earth, there are only very few of them which form rocks.
Difference of lunar rocks and earth rocks?
Lunar rocks are those forming the Moon - as the word 'lunar' says. Earth rocks are formed on Earth - but the rock forming the Moon is also a constituent of the Earth.
Did rocks stopped forming the earth?
no
How does dominant weathering affect which rocks you will see on earth?
it doesnt.

What do rock from Earth and rocks from the Moon have in common?
Many of the rocks of the Moon are described as breccias, that is they are formed from pieces of older rocks. Various types of breccia occur on Earth too, for instance in volcanic regions. Basalt is also common on the Moon, and this is also true of Earth. The Moon has lots of the mineral feldspar, which is also the commonest of the Earth rock forming minerals.
Why do think that the earth was created?
Earth was created as a result of the big bang. Debris from rocks, dust and ice as a result of the bang were squeezed together by gravity, forming spherical planets.
What are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
What happened to the moon when the earth was forming?
billion years ago some planet at size of mars crash into earth then the dust and the rocks left over from the from the crashed planet crates the moon
If new rocks are always forming why is the Earth not getting bigger?
The new rocks don't form from nothing. They form either from material from older rocks that were broken down, or magma that originates inside Earth. As magma rises and erupts as lava from volcanoes the crust will sink down slightly, filling in the space left behind. New oceanic crust is formed as lava erupts at mid-ocean ridges, but at the same time old oceanic crust slides down into the mantle at subduction zones.
What is the common mineral that forms the rocks of earth's crust?
There are several common rock forming minerals, but the most common single mineral of the crust is quartz.
What are the 5 major processes involved in forming sedimentary rocks?
Sedimentary rock formation begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth's surface they begin the long slow but relentless process of becoming sedimentary rock.
Why is it unlikey that fossils would be found in ingenous rocks?
Igneous rocks began as hot, fluid material - from lava erupted at the Earth's surface forming extrusive rocks, from magma (unerupted lava) at shallow depths forming intrusive rocks, or from magma in deep bodies (plutons) forming plutonic rocks. But whatever the form the nature of their formation, the heat at formation, any organic material would immediately burn up rather than become fossilised. The absence of fossils is a simple and obvious indicator that any given contextual rock or strata is igneous.
