How long did it take for the continents to make it to their current postions?
-
200 billion years
-
3000 million years
-
200 million years
Correct Answer
A. 200 million yearsExplanation
The correct answer is 200 million years. This is the estimated time it took for the continents to move and form their current positions on Earth's surface. This process is known as continental drift or plate tectonics, which involves the slow movement of Earth's tectonic plates over millions of years. Through this process, the continents have shifted and collided, forming the continents as we know them today.Rate this question:

What was the name of the super-continent?
-
Pangeo
-
Pang
-
Pangea
Correct Answer
A. PangeaExplanation
Pangea is the correct answer because it was the name of the super-continent that existed around 300 million years ago. Pangea was a massive landmass that contained all of Earth's continents before they started to drift apart. This theory is supported by geological evidence such as the matching shapes of coastlines and similar rock formations found on different continents.Rate this question:

What layer of the earth do tectonic plates occupy?
-
Lithosphere
-
Curst and Upper Mantle
-
Asthenosphere
Correct Answer
A. LithosphereExplanation
Tectonic plates occupy the lithosphere, which is the outermost layer of the Earth. The lithosphere is made up of the crust and the uppermost part of the mantle. It is divided into several large and small plates that float on the semi-fluid asthenosphere beneath them. These plates interact with each other, causing geological phenomena such as earthquakes, volcanic activity, and the formation of mountains.Rate this question:

How many types of plate boundaries are there?
-
2
-
3
-
2.5
-
4
Correct Answer
A. 3Explanation
There are three types of plate boundaries: convergent, divergent, and transform. Convergent boundaries occur when two plates collide, causing one plate to be forced beneath the other. Divergent boundaries occur when two plates move away from each other, creating new crust. Transform boundaries occur when two plates slide past each other horizontally. Therefore, the correct answer is 3.Rate this question:

Which bondary has three sub-types?
-
Divergent
-
Convergent
-
Transform
Correct Answer
A. ConvergentExplanation
Convergent boundaries have three sub-types: oceanic-continental convergence, oceanic-oceanic convergence, and continental-continental convergence. In these boundaries, tectonic plates move towards each other, leading to the formation of mountains, volcanic activity, and earthquakes. The collision of plates can result in the subduction of one plate beneath another or the uplifting of crustal material. Therefore, convergent boundaries are characterized by intense geological activity and the creation of various landforms.Rate this question:

What boundary were the Himalayas created?
-
Divergent
-
Convergent
-
Transform
Correct Answer
A. ConvergentExplanation
The Himalayas were created as a result of convergent boundaries. Convergent boundaries occur when two tectonic plates collide, causing one plate to be forced beneath the other in a process called subduction. In the case of the Himalayas, the Indian Plate collided with the Eurasian Plate, leading to the uplift and formation of the mountain range. This collision continues to this day, causing the Himalayas to grow taller each year. Therefore, the correct answer is convergent.Rate this question:

What boundary is sea-floor spreading applied?
-
Divergent
-
Convergent
-
Transform
Correct Answer
A. DivergentExplanation
Sea-floor spreading is a geological process that occurs at divergent boundaries, where tectonic plates move away from each other. As the plates separate, magma rises from the mantle, creating new oceanic crust. This process results in the formation of mid-ocean ridges and the spreading of the sea floor. Therefore, sea-floor spreading is applied at divergent boundaries.Rate this question:
