Question

Earth’s surface is broken into large pieces that are slowly shifting. This gradual process, known as plate tectonics, accounts for movement of entire continents over time. During the past century, geologists have found multiple lines of evidence that support the theory of plate tectonics, including the mechanism that drives the plates’ motion—sea floor spreading. As a result, sections of Earth’s crust are constantly being pulled apart or pushed together. This movement creates many of Earth’s landforms, such as mountains, rift valleys, and volcanoes.

According to the theory of plate tectonics, 250 million years ago all of Earth’s landmasses were clustered into one supercontinent, known as Pangea. Based on the past and current movements of Earth’s plates, predict how the location of the continents might shift during the next 250 million years. Do you think they’ll spread out, cluster together, or move in a combination of the two? What types of landforms do you anticipate forming as a result? What effect, if any, do you anticipate this movement will have on life on Earth?

Answer 1

Based on what I have learned this year and past knowledge, I think they will move in a combination of two. The tectonic plates move around the planet but move very slowly, only a few centimeters per year, which plays a big part in the picture. If you look at California, It's splitting! But who is to say that the continents will not cluster to another land as it spreads out. There's also not enough space on earth for every piece of land. But when they do end up clustered together, mountains will be formed, and if they spread out, faults will be created. So I think in 250 million years we will have another supercontinent like Pangea. I also believe that there will be many new geographical changes, including volcanoes, more mountains, and deeper oceans. This will also cause new Invasive species and the destruction of man-made buildings.

Presently the plates are moving towards each other and will eventually merge into one landmass once again. Presently Africa I moving towards Europe and Asia and will merge with that landmass, closing the Mediterranean Sea. When plates move towards each other extensive fold mountain ranges will form; a modern day example is the Himalayan mountain range. This type of movement will impact ocean currents as we know it and bring about a dramatic change in the climate. Disruption of currents and the closure of some water ways and oceans will lead to the extinction of some species. Leaving only those who are able to adapt to the new climatic conditions.
