<h3>What is earth rotation?</h3>
The rotation of the planet Earth around its own axis and variations in the orientation of the rotation axis in space are referred to as Earth's orbit or Earth's spin. Earth rotates prograde in an easterly direction. The Earth rotates counterclockwise when viewed from the northern polar star Polaris. The Northern Hemisphere's North Pole, sometimes referred to as the Geographic North Pole or Terrestrial North Pole, is where the Earth's axis of rotation and surface meet. The North Magnetic Pole of the Earth is distinct from this place. The other location where the axis of rotation of Earth crosses the surface is the South Pole, which is located in Antarctica. The Earth revolves once every 24 hours or so in relation to the Sun, but only once every 23 hours, 56 minutes, and 4 seconds in relation to other far-off stars.

The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]
Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]
Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.
The correct answer should be D. Studies have been inconclusive regarding the nutritional value of organically grown food and conventionally grown food.
There has yet to be found a conclusive evidence that organic food is better. Most of the things that people hate about regular food is easily removed either by washing the food such as fruits or vegetables or by cooking them in any way. Risks of illnesses and diseases is also not related to the difference between them.
Answer:
analysis of magnetic and seismic patters
Explanation:
The proof for the long-doubted idea of drifting continents came in the form of analysis of magnetic and seismic patterns understanding of mountains glacial ice animal distributions analysis of magnetic and seismic patterns.
It simply means seismic and magnetic patterns which are measured through some designated machines are instrumental in the understanding of mountain glacial ice animal distribution.
