The transition zone between the crust and mantle is called as mohorovicic discontinuity.
The mohorovicic discontinuity was discovered by Andrija Mohorovicic in the year of 1909. The Moho lies at the depth of 35km beneath the continents and 8km beneath the oceanic crust. The Moho separates both the continental crust and the oceanic crust from underlying mantle. The Moho lies almost entirely within the lithosphere, only beneath the Mid Oceanic Ridge does it define lithosphere and asthenosphere boundary. Immediate above the Moho velocity of the P wave is 6km/sec and just below the Moho it becomes 8km/sec. Moho is characterised by up to 500km thick.
The Mohorovicic Discontinuity marks the lower limit of Earth's crust. It occurs at an average depth of about 8 kilometers beneath the ocean basins and 32 kilometers beneath continental surfaces. Mohorovicic was able to use his discovery to study thickness variations of the crust.
Mohorovicic discontinuity is the layer which is between the earth's crust and mantle. It's density ranges from 3.3 to 3.7.

<span>The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat. Thats why his statement is incorrect.</span>
<span>Fasten pedestal and bench grinders on a solid surface securely.Ensure all the guards are in place and secure before using a grinder.Adjust tool rests to within 3 mm (1/8 in.) of wheels. Never adjust rests while wheels are moving. Work rest height should be on horizontal centre line of the machine spindle.Maintain 6 mm (1/4 in.) wheel exposure with a tongue guard or a movable guard.Check that wheels have blotters on each side.Check the wheel fits properly to the spindle when mounting. If it is loose, get another wheel.Tighten the nuts before you turn the grinder on.Before you plug in the grinder, manually spin the wheel to make sure it is spinning freely.</span><span>Make sure the cables are not damaged and in good condition.Keep the cables out of the work area.<span>Wear proper personal protective equipment:<span>eye, ear and face protection,metatarsal safety boots, where required,respiratory protection may be required, depending on the work.</span></span>Wear gloves only where necessary and if there is no risk of entanglement.Stand to one side of the grinder until the wheel reaches operating speed.Bring work into contact with the grinding wheel slowly and smoothly, without bumping.Apply gradual pressure to allow the wheel to warm up evenly. Use only the pressure required to complete a job.Move the work back and forth across the face of the wheel. This movement prevents grooves from forming.<span>Wheels are made only for grinding certain items. Do not grind rough forgings on a small precision grinding wheel. is that enough</span></span>

The scientific law of one organism feeding off to other where energy is transferred from one form to another is known as the law of conservation of energy.
Explanation-
Energy from the the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.
The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.
