There aren't any continents

Tilt is the world you're looking for. "Angle the rotational axis makes with the perpendicular to the ecliptic plane" would be more accurate.

The Continental Drift theory is a theory because there is no evidence to support it. Alfred Wegener developed the Continental Drift theory in the 1800's.

Meteorite craters.

the earth doesnt fall.

Deep-sea sediments most likely contribute to continent growth by being scraped off in a subduction zone and left at the surface.

The ratio of the concentration (by weight) of an element (e.g. Ti) in a crystallizing mineralto its concentration in the magma. For example, KTi = [Ti]min./[Ti]magma, where kTi is the partition coefficient for Ti, and [Ti]min. and [Ti]magma are the concentrations of Ti in the mineral and magma respectively. The value of k is dependent on temperature, pressure and the composition of crystallizing mineral and magma.

The wave are classified as their motion respect to their propagation.

The typical tidal range in the open ocean is about 0.6 meters (2 feet). As you get closer to the coast, however, this range gets much greater. Coastal tidal ranges vary globally and can differ anywhere from 1.8 meters to 3 meters (6–10 feet). The world's biggest tidal differential occurs in the Bay of Fundy in Eastern Canada, where the sea level changes by up to 17 meters (55 feet) during the day. Ungava Bay in Northern Quebec, north eastern Canada, is believed by some experts to have higher tidal ranges than the Bay of Fundy (about 17 metres or 56 ft), but it is free of pack ice for only about four months every year, whereas the Bay of Fundy rarely freezes. What is generally regarded as the next highest tidal range occurs in the Bristol Channel in the UK, where sea levels change by some 15 meters (49 feet). The smallest tidal ranges occur in the Mediterranean, Baltic, and Caribbean Seas. A point within a tidal system where the tidal range is almost zero is called an amphidromic point.

maybe; the more powerful the earthquake, the more likely you are to feel it.

Use a compass. It's needle points to the south pole of a magnet.

I presume you mean to ask "Why is it that some organisms are unchanged even after geologic time periods while others have been greatly altered?"

Entire books can (and have) been written about this subject.

Evolution - despite what some people think of it - does not *require* change to occur. In fact, in a stable environment it tends to discourage it. However, if change occurs and works better than what is already present, evolution encourages the change to remain, eventually replacing or diverging from the former (unchanged) population.

If the environment in which an organism exists is relatively stable over geologic times and the organism is well adapted to said environment, most changes will be discouraged by evolution. This is because if the organism is well adapted to the (stable) environment, then any changes from it are likely to be away from well adapted - and thus a disadvantage. Those with the change likely to become a snack (due to a change that makes it easier for predators to find them) or malnourished (due to a change that made it harder to find / consume food), or otherwise at a disadvantage. Such creatures are less likely to live to be old enough to breed, and if by chance they do breed, their children are themselves unlikely to live long enough to breed - and so forth each generation until the changed sub-species is extinct.

Most creatures that are unchanged after geologic times live in very very stable environments - the bottom of a sea (ceolecanth), the tropic jungles, and so forth. If the area is isolated it helps, as it discourages change (lack of new predators / prey entering the area, such as with australia, madagascar, new zealand, and so forth.

The tropic jungle comment may seem strange, but if you consider it you will see that the temperature is the same year round, rainfall is similarly consistent, and so forth. The vegetation can be thick enough and the biodiversity dense enough (all niches filled) to slow the spread of new creatures somewhat.

Evolution only becomes an encourager of change when change is entered into the system from another source - changing seasons, changing competitors / predators / prey, changing vegetative patterns, changing food sources, new niches opening, and so forth. Then evolution rather rapidly encourages new adaptions.

This is a hard question to answer, as the depth of a focus depends upon the type of fault or formation that is being discussed. North America has a range of these, so it varies greatly across the continent.

Seismic impact refers to the effects of an earthquake on buildings, infrastructure, and people in a given area. It can include damage to structures, injuries or fatalities, disruption of utilities, and economic losses. Understanding seismic impact is important for assessing risk, designing resilient structures, and planning emergency response strategies.

Hopefully, this is a thought experiment!

It is gravitational attraction that keeps objects "stuck" to the Earth, so if the Earth split into half, you would still be attracted to it - although by half as much (as the mass of the Earth would have been halved). So you still couldn't fall off.

To cause a tsunami a vast amount of water must be displaced suddenly. The sudden sinking or uplifting of large sections of the crust during an earthquake are one means of doing this. Another means is an impact event. If a large enough meteor or comet were to impact the ocean a tsunami could also form. Lastly, an underwater landslide could cause a tsunami - although these are usually triggered by earthquakes, either in the sea or in the land near the shoreline.

I believe your question is also asking if a tsunami might form from an earthquake on land perhaps near the sea? This could only work if the land moved laterally - side to side - instead of vertically. In other words, if the land moved out into the sea far enough over a significant length of shoreline then enough water might be displaced to cause a tsunami. This would require a significant ripping of the crust apart further inland, however, which is rare. The only example I can think of at present is the African rift valley system.

Yet even this has not yet - to my knowledge - produced tsunamis, or at least none of measurable force / height.

A super continent called Pangaea.

A big rock from space could split the crust, or at least punch a hole in it. (And this has happened! And on several occasions.) We've had some really, really big hits, including one that is thought to have resulted in the capture and formation of the moon. A hit that massive didn't simply split the crust, but nearly ripped the earth apart. There is also the action of tectonic plates, as the plates respond to gigantic pressures from below. The actions of the tectonic plates had a hand shaping life on earth, and they continue to affect us today. I very big ways, too. Earthquakes arise when plates shift, as you know, but the divergent rifts on some plate boundaries could actually be considered a "functioning split" because the plates are continuing to move apart, continuing to split. Remember that the crust of the earth is an evolving megastructure. The massive dynamics that shaped it in the past continue to shape it now, even though billions of years of have passed since the crust formed.
