TECTONICS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A student argues that the theory of plate tectonics is false because we do not feel tectonic plates moving beneath our feet. What is wrong with this argument?
A
On average, plates move only a few centimeters per year.
B
Tectonic plates are located in Earth’s asthenosphere, too far beneath the planet’s surface for us to feel them moving.
C
The student is correct; plate tectonics is no longer considered a valid theory.
D
Because the plates are all moving at the same speed relative to each other, we do not feel the motion of any single plate.
Explanation: 

Detailed explanation-1: -Because the plates are all moving at the same speed relative to each other, we do not feel the motion of any single plate. Tectonic plates are located in Earth’s asthenosphere, too far beneath the planet’s surface for us to feel them moving.

Detailed explanation-2: -Because plate tectonics explains things, it is a theory, because it does not provide a method to accurately calculate when and where plates move, so it is not a law. Note: Plate tectonics explains the Middle Atlantic Ridge, the African Rift Valley, subduction zones, earthquakes, volcanic locations, and mountains.

Detailed explanation-3: -The mantle sits between Earth’s dense, very hot core and its thin outer layer, the crust. Plate tectonics has become the unifying theory of geology. It explains the earth’s surface movement, current and past, which has created the tallest mountain ranges and the deepest oceans.

Detailed explanation-4: -Tectonic plates move around and can cause earthquakes and volcanic eruptions. First of all, it is important to know that the Earth’s crust is broken up into large pieces called tectonic plates. Remember, tectonic plates are giant pieces of the Earth’s crust that fit together and move around on the Earth’s surface.

Detailed explanation-5: -In the early 20th century, a scientific theory called continental drift was proposed about this migration of the continents. That theory was initially ridiculed, but it paved the way for another theory called plate tectonics that scientists have now accepted to explain how Earth’s continents move.
