The Earth’s crust has several moving pieces. They are composed of a variety of igneous metamorphic and sedimentary rocks. The tectonic plates are always colliding or pulling apart, creating mountains. Earthquakes and volcanoes occur at the edge of these tectonic plates because of the impact of the plate movements are greatest there. What would be interesting is what if plate tectonics never existed? What would be the social, economic, climatic impact of living without plate tectonics? Without tectonic forces that push and pull apart our lives would be different from how we know it. Humans would be much safer. The average number of people affected is about 218 million people by natural disasters from tsunamis, earthquakes, and volcanic eruptions. Far less human deaths and less destruction as a whole if we didn’t have plate tectonics. Countries would save on the economic losses from very huge earthquakes. Governments typically have to spend large amounts of money to rebuild homes, and reestablish the damaged infrastructure. …show more content…
Pangaea wouldn’t have separated without the plate tectonics moving and shifting. Life as we known it would be less diverse and evolution wouldn’t have such a great role as it has. One example is when Madagascar broke off from Africa about 160 million years ago. Most of the animals found on that island are not found anywhere else on the planet. The idea of having a modern day Pangaea would mean that the interior of the supercontinent would be dry and hot and the out skirts of Pangaea would have moisture-bearing clouds. One example would be that a larger area of land is likely to follow a stronger seasonal pattern of climate. Without mountains there would be a more uniform distribution of rainfall throughout the whole world. Currently, when plate tectonics shift they cause the earth to get
Rocks are heated underneath the crust then pushed out through a volcano or the oceanic plate. The rock substance that becomes the crust will deposit back underneath the crust. All of the process can be credited to the dynamic nature of Earth.
When the layers of the Earth move it causes the tectonic plates (aka: plate tectonics) to move which causes the Alaskan Way Viaduct to collapse. The layers of the Earth are the inner core, outer core, mesosphere, asthenosphere, upper rigid mantle, oceanic crust, and the continental crust. The Density Column lab showed how things can have different densities like the layers of the Earth. It also showed how things that are most dense stay more towards the bottom and least dense stuff stays more towards the top.
The Connecticut river valley was also formed from many rifts and faults that had developed. A rift valley is a region of lowland that forms where tectonic plates move apart, which is how the river valley was formed. On the other hand, the plate tectonics also formed the Appalachian mountains. The Appalachian mountains were formed by convergent boundaries, which is when two plates collide. The
The two plates that moved were the North American tectonic plate and the Pacific tectonic plate. The plates moved about 15 feet, this is huge because the average movement of tectonic plates during an earthquake is only 2 inches. The earthquake only lasted a minute but it quickly destroyed the city. The earthquake
APUSH Summer Assignment Terms Christopher Columbus: A skilled Italian seafarer that persuaded the Spanish Monarchs to give him three tiny ships in order for him to make his journey to the “New World”. Columbian Exchange: A trade in international commerce that traded things from the New World and the Old World. Conquistadores: The Conquistadores were the first ones to enter the “New World”.
Plate tectonics is a theory that Earth’s crust is composed of nearly a dozen plates, which have shifted around the surface of the Earth over time. This theory provides a reasonable explanation for how mountains formed, and why there are earthquakes and volcanoes. Additionally, this
Minnesota is home to many geological wonders. Whether it be the formidable cliffs of the North Shore, one of thousands of pristine lakes, or the miles of rolling farm land; Minnesota has much to offer. Each state has very different geology, and because of that, each state uses their geology in different ways. The geology of Minnesota plays an important role in many different aspects of our lives including our health, economy, and heritage. If the geology of Minnesota would have been different, there is no doubt that the state would be different today as a result.
The earth is like a jigsaw puzzle, it moves in someway or another all of the time. The tectonic plates that form the surface of the Earth are often sliding against each other, which triggers earthquakes. The 1960 Chile Earthquake was the largest earthquake ever recorded which had a tremendous impact not only on the immediate area and the people living there, but also on the rest of the world. The 1960 was the largest earthquake ever recorded.
Continental crust creates the land and mountains while oceanic
Water rising due to climate change is impacting people by causing islands to get flooded. This causes people to have to evacuate and find new homes, which can cause overpopulation in some cases (Doc G & H). Climate change is also impacting people because of health. The warmer temperatures cause there to be longer pollen seasons since the cold comes later and goes away sooner (Doc E). This makes for miserable and potentially dangerous summers for people who are allergic to pollen (Doc F).
Yellowstone and The Big Hawaiin Island could both very easily change in one day. Both of these island have large volcanos. Both could still erupt any day. But both of these could have very similar other features. Hawaii and yellowstone are very alike and very different.
How do earthquakes form? Earth quakes form when two earth blocks slide past each other. When they slip past each other it is called a fault. Earth quakes
These include floods and droughts. However, the most concrete impact recently has been by drought. The government and the people have not been able to provide enough food supply for themselves. Due to the growth
These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
When two plates rub against each other, they often get stuck. If pressure builds up, it eventually becomes too great and the rock breaks, releasing waves of seismic energy. The spot underground where the rock breaks is called the focus of the earthquake. The ground above the focus is called the epicenter of the earthquake.(6) A solution to the injuries caused
