What are the 5 evidence of continental drift?
The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
Why was Pangea not accepted?
This idea was quickly rejected by the scientific community primarily because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents.
What broke Pangea?
During the Triassic Period, the immense Pangea landmass began breaking apart as a result of continental rifting. A rift zone running the width of the supercontinent began to open up an ocean that would eventually separate the landmass into two enormous continents.
Can Pangea happen again?
The last supercontinent, Pangea, formed around 310 million years ago, and started breaking up around 180 million years ago. It has been suggested that the next supercontinent will form in 200-250 million years, so we are currently about halfway through the scattered phase of the current supercontinent cycle.
Who traveled to 6 continents in 100 hours?
What’s the oldest continent?
Will the continents collide again?
The Earth’s continents are in constant motion. On at least three occasions, they have all collided to form one giant continent. If history is a guide, the current continents will coalesce once again to form another supercontinent. And a study in Nature now shows how that could come about.
Was all land on Earth connected?
This giant landmass known as a supercontinent was called Pangea. The word Pangaea means “All Lands”, this describes the way all the continents were joined up together….Earth’s Tectonic History.

How did the 7 continents separate?
It wasn’t until 1912 that meteorologist Alfred Wegener hypothesized that the seven continents had once been joined as a supercontinent. He claimed the lands separated 250 million years ago by the process of continental drift, which means the continents just slowly fractured and went their separate ways.
Can the earth break apart?
New research reveals that when two parts of the Earth’s crust break apart, this does not always cause massive volcanic eruptions. The Earth’s crust is broken into plates that are in constant motion over timescales of millions of years. Plates occasionally collide and fuse, or they can break apart to form new ones.
What would happen if the Earth stopped spinning for 42 seconds?
Assuming that the earth stops suddenly for 42 seconds and then starts spinning again at its normal speed, here’s what would happen: 1. If the earth stops spinning suddenly, the atmosphere will continue to spin. The winds will also cause erosion to the earth’s crust.
What would happen if the earth split in half?
As the Earth is methodically sliced in half, its mantle and core would be exposed to the vacuum of space, causing massive earthquakes that would be felt everywhere on the planet. Those who are the furthest from the split would have the best chance of surviving the longest, at least from the initial earthquakes.
Can we live without moon?
Without a moon the tilt of our earth’s axis would vary over time. This could create some very wild weather. Right now, thanks to our moon, our axis stays tilted at twenty-three point five degrees. But without the moon the earth might tilt too far over or hardly tilt at all leading to no seasons or even extreme seasons.
What would happen if the Earth was swallowed by a black hole?
The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.
Would you die if you went into a black hole?
Although their gravity is stronger, the stretching force is weaker than it would be with a small black hole and it would not kill you. The bad news is that the event horizon marks the edge of the abyss. Nothing can escape from inside the event horizon, so you could not escape or report on your experience.
Is dying in a black hole painful?
If you’re falling into a stellar black hole, you’ll start feeling uncomfortable within 6,000 kilometers (3,728 miles) of the center, long before you cross the horizon [source: Bunn]. Either way, spaghettification leads to a painful conclusion.
What are the fastest tectonic plates?
These average rates of plate separations can range widely. The Arctic Ridge has the slowest rate (less than 2.5 cm/yr), and the East Pacific Rise near Easter Island, in the South Pacific about 3,400 km west of Chile, has the fastest rate (more than 15 cm/yr).
How quickly do tectonic plates move?
They move at a rate of one to two inches (three to five centimeters) per year.
What is the most dangerous plate?
What is the most dangerous type of plate boundary and why?
In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
