What else can I help you with?
One reason that molten rock at the surface is different in composition from molten rock underground is that?
minerals are added as moltenn rocks melt other rocks
What is a reason that molten rock at the surface is different in composition from molten rock underground?
Magma is a combination of molten silicate minerals and volatiles (gases) and Lava loses many of these volatiles (gases) when it comes in contact with the atmosphere; hence each has a different chemical composition. This is true. Also, temperature and pressure conditions differ from the surface to underground, so different crystals (that make up the magma and lava) will form. Furthermore, the composition of the magma (below ground) may be different to the lava (above ground), so the resultant rocks may have differing chemical compounds composing them.
What is one reason that matter is able to move around within the Earth?
The interior of the earth is molten.
Why are there different types of map projections?
=The curved surface of the earth cannot be shown accurately on a map because such a surface must be stretched or broken in some places as it is flattened. For this reason mapmakers use map projections.=
What is the reason the high surface tension of water?
The reason behind the high surface tension of water is hydrogen bonds. This very strong bond enables small insects to walk on the surface of water.
What are the three properties of mixture?
1) There is no fixed composition in mixtures. Eg. Copper and tin are mixed together in variable ratios to form brass. Therefore, it is a mixture. 2) Mixtures do not have a fixed boiling point. This is due to the varying composition of its constituents. Its different constituents have different boiling points, therefore resulting in its unfixed boiling point. 3) Mixtures do not have a fixed boiling point. The reason is similar to the reason given for its unfixed boiling points. Hope this helps (: -babyhamsterx
The reason we observe different rates of acceleration in objects is due to wind?
The different rates of acceleration in objects are primarily influenced by factors like gravity, mass, and the surface characteristics of the object and the surface it is on. While wind resistance can affect the motion of objects, it is usually a minor factor compared to these other influences.
Why does the sun have such a strong gravitational pull?
The acceleration of gravity on the surface of any astronomical body depends on its mass and the distance of its surface from its center ... the 'radius'. Whatever the nature of gravity on its surface is, that's the reason. I was about to say "It doesn't.", but I don't know whether you consider Pluto to be a planet any more. Mercury's gravity is more than 6 times as strong as Pluto's is. And it's also more than double the strength of gravity on the surface of our Moon.
What is the main reason why the surface of Venus is so hot?
The main reason why the surface of Venus is so hot is due to its thick atmosphere that traps heat from the sun, creating a greenhouse effect.
Why the end of a glass rod becomes round on heating reason?
when glass rod is heated ,it melts. Now a liquid having surface tension ,tends to have least surface area.we know that a spherical surface has least surface area compared to other shapes of same volume.so end of a glass rod becomes round when heated .........geddit :)
When you are using elevated surface from bottom to up is distance varies with time?
No. There is no reason to suppose that the elevated surface is moving.
When the earths shadow falls on the moon?
The shadow of the Earth on the moon's surface is the reason that it takes different phases. When the Earth completely occludes the moon, it is a new moon, and when there is no shadow, it is a full moon.
