Earthquakes Volcanoes and Mountain Ranges
Earthquakes, Volcanoes and Mountain Ranges
Volcanoes, earthquakes and many of the great, in size, mountains (the Himalayas, Rockies, Urals, Alps, and the Appalachians) will all be marked on my map at some point in this project. Now just let me tell you some interesting facts about some of these topics.
Since recorded history, 550 volcanoes have erupted on the earth’s surface, but even far more have erupted unobserved on the ocean floor.
The enormous Himalayas and many other great mountains are known to be young Fold Mountains. Young, because these have been formed relatively recently in the earth’s history, compared to other mountain ranges like the Aravallis in India and the Appalachian in the USA. These are known as fold mountains because they extend for 2500 km in length in a series of parallel ridges or folds. This information has been found using a theory that took place in 1912, by a German meteorologist, named Alfred Wegener. This theory is the Theory of Continental Drift.
In the real ocean, plenty of natural disasters can trigger a similar event. Caused by a paddle-effect of an earthquake, underwater volcano or even an asteroid, sunamis are enormously dangerous stealth waves that travel vast distances across the ocean.
Is there a pattern or repetitiveness in certain areas on earth where volcano’s, earthquakes and mountain ranges commonly appear?
a) Earthquakes are most likely to occur where tectonic plates meet or hit each other.
b) Volcanoes are most likely to occur where tectonic plates split apart or separate from each other, allowing magma to come up through the cracks.
c) Mountain ranges are most likely to occur where one plate slips under another allowing the magma to come up or collide and push up on each other.
The materials that were used during this project were Science and Technology, The Complete Atlas of the World, the computer, the Internet, pens and pencils.
The different steps I took at conjuring up information to apply to the work that has been assigned, was to:
Step 1) Check in my science textbook, to find the longitude and latitude for each of the huge volcanoes and earthquakes that have happened in history and mark them on my map.
Step 2) Check in my atlas, to find the huge mountain ranges that still stand today and mark them on my map.
Step 3)...
