What causes the liquid mantle part of the earth to move?

Answer 1

Firstly, the mantle is a solid, not liquid. It 'flows' over geologic time, but it is still solid rock, kind of like silly puddy. The core has a liquid part and a solid part. The mantle's movement is mainly caused by convection, but the superficial effect of plate movement is debateable. It's a chicken-egg thing; the plates move and cause convection or vice-versa. Most think plate movement is caused by density contrasts. The outer liquid core is believed to move due to rotational forces, and this causes a dynamo that creates the earth's magnetic field.

Answer 2

There won't be a liquid mantle. If the earth had a liquid mantle it would rip the earth right into a million products because of the fact of centrifugal tension. additionally many earthquakes originate on the depths of the place this liquid mantle is and earthquakes can't kind the place there is not any good shape to resonate. in fact there are various circumstances of earthquakes as far down as seven hundred miles under the floor and that i think of the element at which all supplies start to break down into flowing liquid count or plastic basalt is one hundred fifty-2 hundred miles..different wave lengths sent contained in direction of the earth to confirm what number cases the waves refract (P and S or shearing wave) is meant to coach that the cloth is transforming into denser till it reaches the element the place the density decreases so hence the pliancy is increasing. In different words the waves are traveling around the indoors middle because of the fact its believed to be especially liquid...Now that's the well known thought or perhaps Albert Einstein himself shaped an equation to purpose and confirm different densities of our planet by ability of what number cases a wave refracts.. Im not claiming to be Einstein, however the element is we dont understand if the mantle is liquid or merely empty area because of the fact the sound waves might behave further in the two circumstances. one factor is for specific and that i discussed this formerly on a till now post. all of us understand little or no with regard to the interior and that's larglely guesswork. for occasion interior the 1970's a venture began in Northern Siberia referred to as the "Kola properly" or "super deep properly" venture. by ability of the early Nineteen 1890s that they had reached the intensity of approximately 7 a million/2 miles under the floor and that's as far as guy has ever gotten. The scientists fairly concluded that what they concept they might discover at those depths became not and so that they theorized that because of the fact the nice and cozy temperatures weren't increasing that it had leveled off and quicker or later in the event that they saved digging the temperature might start to chop back. that's speculative in nature, even nonetheless it makes a good element because of the fact a million.) we've in user-friendly terms pricked the floor of the "apple" it fairly is our planet 2.) Seismology and determining the character of the earths indoors is fairly wager artwork 3.) no you possibly can be for specific what is going on interior the interior till have been stepped forward adequate to get there.

Answer 3

The mantle must contain some iron, nickel or cobalt, so it could also be magnetic forces from the Sun that cause it to move. Uneven cooling could lead it to expand and contract in different directions. When continents collide (leading to earthquakes and volcanoes) the resistance could cause a drag on the motion of the mantle.

Answer 4

The rotation of the earth on it's axis. Since the earth is moving one way due to the gravitational forces between it and the sun, the liquid core is moving in the opposite direction....

Answer 5

Convection from the heat being generated at the core by the georeactor there. The heat creates convection and then the other forces, like the rotation and gravitational forces create the variations and distortions in the flow. These massive convection rivers produce low voltage massive amperage currents that cumulatively result in the overall magnetic field we experience.

Answer 6

The internal heat and movement are leftover from the cataclysmic impact which set the earth spinning at an angle to the solar plane, and created the moon. The earth has been cooling for 4.5 billion years, and still has a long way to go.

Answer 7

If I were a top with a liquid center spinning

Answer 8

Gravitational forces from the sun and moon

Answer 9
