tectonic movement can cause tectonic plates to collide, drift apart, or slide across one another

The difference in arrival times of P and S waves.

Pangaea (also Pangea) was the collection of all land masses on Earth around 250 million years ago, which broke into the current landforms through continental drift.

Pangaea is from the Latin for "entire Earth".

as v=f/\(lemda), it shows that velocity dependx on the frequency of wave i.e numbr of wavs produced in one second and wavelength(lemda) which is the distance between two consecutive crests or troughs in transverse waves nd in longitudnal waves it is distance betwen two consecutive compressions or rarefactions.

Continental Drift is important because we live in an environment where if we were to still be, "attached," to different continents, we wouldn't be able to travel and explore the different places that cultures have to offer.

thermal convection is the primary force that cause the sea floor to spread

When a mound of magma forms on the floor of a caldera, it can lead to increased pressure and potential eruptions. As the magma accumulates, it can cause the caldera floor to rise, potentially leading to uplift and deformation of the surrounding area. This can be a precursor to an eruption if the pressure continues to build.

Heat travels in the form of infrared radiation. You don't use radiation to
detect radiation. You use a detector that responds to the type of radiation
you're trying to detect. In the case of infrared radiation, your skin makes an
excellent detector.

Mudflows could very well be an agent of erosion. Their massive weight will move anything in their path. Rocks right up to boulders can be swept down in the rush of the material in response to gravity. And they can be extremely abrasive depending on the material suspended in them. It is the moving mass of mudflows that gives them the ability to "power through" anything that extends up even a fraction of an inch above "ground level" that makes them unstoppable. You've seen what water slamming into things does. Imagine "water" that has several times the mass of liquid H2O (which mud has) slamming into a bank of earth or into a pile of rocks. Goodbye earth or rocks.

Continental drift creates separate continents. These continents will have the populations confined to reproduction of isolated gene pools (all set of alleles of individuals that make up a population). In other words, a population of species 1 living on a new continent will only be confined to reproduce with the individuals of the population living on that continent. Keep in mind that the smaller the population, the lesser the variation they will have, because only the fittest will survive with those environmental conditions. This will mean a smaller gene pool, and with these populations adapting to their new environments, they will eventually speciate.

No, only Continental Drift Theory.

Continental drift is the movement of the Earth's continents relative to each other. The hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s, that a sufficient geological explanation of that movement was found.

Continental drift referred to the concept that the Earth's continents were once part of a large supercontinent and had subsequently split apart and arrived at their present destinations.

Continental drift theory has been replaced by the science of plate tectonics, an all inclusive explanation of the process of continent movements, crust creation, lithologies, subduction, the rock cycle, and so on. The engine behind plate tectonics is heat from the interior of the Earth. This heat is a combination of heat from radioactive decay, remnant heat from Earth's formation process, and crushing pressures from its mass.

Heat rises through the mantle outward toward Earth's surface. In a layer of the upper mantle known as the asthenosphere, the solid rock is plastic-like, enough so that the rock slowly flows in a current. The current rises to reach its maximum height at a weakness in the hard uppermost mantle with attached crust known as the lithosphere. At these points, the hot mantle rocks melt from the lowering of lithostatic pressure and rises to form new crust at the mid-ocean ridges. As new material is added at the ridges, the tectonic plates on either side move apart. Over time this causes the continents located on the plates to "drift' apart.

At the other end of the current, older, denser crust is being pushed under less dense crustal plates and less dense oceanic plates, in a downward trajectory toward the mantle, where it melts and gradually becomes part of the mantle rock once again. The Pacific Ocean is gradually shrinking due to the subduction of its boundaries in an area known as the Ring of Fire. One day it will cease to exist, and once again there will exist a supercontinent.

Tornado season in Indiana typically occurs from April to June, with May historically having the highest frequency of tornadoes. However, tornadoes can occur at any time of the year in Indiana. It is important for residents to stay informed about severe weather and have a plan in place in case of a tornado.

The continents do not "drift" in the usual sense of the word. They are held tightly together on the numerous plates, and move because they are being pushed, squeezed, and/or lifted. At no time are they free to move about with no other plates packed around them.

Continental Drift is a theory developed in the 1900s by a German scientist named Alfred Wegner. He believed that the continents all fitted together at one point and published a book explaining it in 1915. He believed that the Earth 200 million years ago had one large landmass, aka Pangaea. His theory stated that the Earth's continents split up over time to create the continents we know today. He believed that this could be proven, and found a 250 million seed fern whose seeds could not travel long distances (not over oceans). Wegner died in a blizzard in Antarctica looking for the fern after he found it on other continents. Not until the 1960's did scientists find the fossil evidence to be good enough to prove that all land was joined at one point in time. Sea-floor spreading is another phenomena that science finds to be proof of Pangaea.

The general result is to make the ocean basin wider.

Earthquakes can happen, but on small scales, the country does not lie on a tectonic plate, so they will not occur

Earth's tilt causes seasons based on what direction its facing the sun. The tilt allows Earth to have different seasons in different places in the world. If Earth didn't have its tilt each place would only have one season all year long.
