If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? Well, this claim was made in the 90’s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930.
Wegener’s theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Over time, the landmass broke and drifted away and is still drifting to this day. In his proposal, he stated that the super content, which he named Pangaea, meaning ‘’all earth” once existed. The supercontinent was surrounded by water bodies, mainly oceans, and seas.
Mountain ranges provide evidence because they are separated by bodies of water on different continents. If the pangeia existed, these mountain ranges would be equal because the continents would be placed next to each other.
Explanation:
The main evidence of the theory of continental drift - and which made it possible to prove it after the Second World War - was the existence of ocean ridges, which are submarine mountain ranges originated by the expulsion of magma through geological cracks, located at points of separation between two tectonic plates.
These mountain ranges provide evidence because they are separated by bodies of water on different continents. If the pangeia existed, these mountain ranges would be equal because the continents would be placed next to each other.
1. The phases of the moon are caused due to the earth's rotations on its axis and the moon rotation around the earth in its elliptical orbit. Certain phases f the moon are caused due to the sun and moon positions about that of the earth on the full moon, new moon and half-moon days. Most of the time we see the same face of the moon.
2. Planet venus show similar properties to that of the moon as both the moon and venus have are made up of same gem material like earth and being a terrestrial planet the venus and both revolve on in the same opposite direction of the earth thus earth sees the same phase of the venus as in the moon.
3. A solar eclipse occurs when the moon blocks the rays id sun and a ring-shaped formations take place when the earth comes in way of the or between the moon and sun the shadows of the earth fall on the moon and hence lunar eclipse takes place.
4. The north star also called the Polaris star seems to change its position for the southern hemisphere, but as for the northern hemisphere, it remains the same as being the north star the equatorial belt the star remains or shows the same side. Due to the rotation and axial tilt of the earth.
5. The cause of sunrise and sunset is mainly due to the sun and the earth's movement around the horizon in the opposite direction and there is 12 hours gap.
The Great Wall of China (traditional Chinese: 萬里長城; simplified Chinese: 万里长城; pinyin: Wànlǐ Chángchéng) is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe.
