Plate tectonic is a scientific theory that says the Earth’s lithosphere is divided into several plates. The plates glide over the mantle. In early 20th century, this theoretical model builds on the concept of continental drift. It was first proposed by the scientist Alfred Wegener in 1912. After seafloor spreading was validated, the theory was accepted by the geoscientific community.
Answer:
This is because of isostatic adjustment.
Explanation:
The mountains of the Himalayas keep growing because of the isostatic adjustment. it allows for a gravitational balance in the Himalayan mountain region, which causes tectonic plates to float below these mountains. This fluctuation occurs in the densest part of the asthenosphere. This density, together with the force of gravity, causes an increase in the height of the tectonic plate that sinks more and more. As the tectonic plate sinks, inversely, this plate rises, when its weight decreases, and it is this rise that causes the mountain to grow.
Answer:Geographic featured that acted as norther borders of the Roman Empire at its height were: Rhine River, Danube River, Carpathian Mountains, and the Black Sea.
Answer: B. Show that light was composed of different colored rays
Explanation:
In the eighteenth century Isaac Newton found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors. He named this phenomenom as dispersion of light.
This phenomenom occurs when a beam of white light (which is compound of many wavelengths or "colors") is refracted (the different rays of light are diverted depending on their wavelengths) in some medium, leaving their constituent colors separated.
