Does earth's molten core affect gravity?
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
Why is there most air closer to the surface?
Most of the Earth's atmosphere is concentrated near the surface due to gravity. The force of gravity pulls air molecules towards the Earth, making the air denser at lower altitudes. As you move higher in the atmosphere, the air becomes less dense because there are fewer air molecules present.
Does heavy rainfall make ocean water more or less dense?
Heavy rainfall makes water less dense because an increase in salinity leads to an increase in density. Rain does not contain any salt. Therefore heavy rainfall makes ocean water less dense. =)
Does gravity increase as you move under the earth?
Yes, but not for quite the reason you might think. If Earth were the same density throughout, gravity would decrease as you moved toward the center, as more and more of Earth's mass would be above you. However, Earth's density is not uniform. Earth's core is made mostly of iron, which is much denser than the rock that makes up the crust and mantle. So gravity would increase as you got closer to the dense. Once you cross into the core, gravity starts to decrease as described above until you reach the very center, where gravity (at least from Earth) is zero.
Which planet has the weakest force of gravity?
Pluto was the smallest planet in our solar system before it was reclassified (though Ceres is even smaller, and was considered a planet longer than Pluto). Because the gravity of an object is directly proportional to its mass and density, that would give Pluto the smallest surface gravity. It is now known that there are a few other large comets out there nearly as big as Pluto (Eris is even bigger). Pluto is no longer classified as a planet because it has not significantly cleared its orbit of debris. Therefore of the eight planets in our solar system, Mercury is the smallest and has the least surface gravity. Mercury is also the most dense, having a large and rich iron core.
Why will the dense area of rock increase the local strength of gravity?
Because it would mean that there is more mass in the same little area, compared to the adjacent areas.
Does larger planets have more gravity than the earth?
It is more accurate to say that more massive planets have stronger gravity. If a planet had the same mass as Earth but a larger radius (i.e. it is less dense) surface gravity would be weaker, as the strength of gravity depends on both an objects mass and the distance from its center.
Why is gravity strongest at Earth's surface?
Gravity is strongest at the earths surface because it's atmosphere is v dense and so the force inc.this happens because force is directly proportional to density.
Is Venus' gravity more or less than earth?
Venus is slightly smaller and less dense than the Earth is, so it has lower surface gravity.
Why does air become less dense as you increase altitude?
gravity, denser things go down. -earth science student
Which one of the following objects will have the greatest force of graity to the earth at its surface?
The object with the greatest force of gravity to the Earth at its surface would be a lead sphere. This is because the force of gravity is directly proportional to the mass of the object, and lead is a dense material, resulting in a larger force of gravity.
How are the planets sizes related to their surface gravity?
Planet sizes are directly related to their surface gravity due to their mass and radius. Larger planets typically have greater mass, which increases their gravitational pull. However, if a planet is significantly larger but less dense, its surface gravity may not be as high as expected. Thus, surface gravity is influenced by both the planet's size (radius) and its density (mass per unit volume).
When is gravity at the largest?
Gravity is related to Mass and distance. Thus gravity increases the nearer you get to a dense massive body.
What is 'dense glass'?
Dense glass refers to glass that has a high specific gravity or high density, which makes it heavier and more resistant to breakage compared to regular glass. It is often used in specialized applications where durability and strength are important.
Can earths gravity increase or decrease?
Yes, it is not a constant. The force of gravity is related to the distance from the centre of the earth so that the force of gravity will be slightly reduced at altitudes. Also, the earth is not a perfect sphere - it bulges at the equator and is flatter at the poles. So the force of gravity will be greater at the poles. The force of gravity is also affected by what is under the surface: if standing over dense rocks, the force will be greater. Finally, the force of gravity is also higher after heavy rainfall. [I guess that is because the water fills up all the air gaps in the soil and so increases its density.]
How is gravity used in the procss of convection?
Gravity causes the less dense stuff to rise
Does earth's molten core affect gravity?
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
