Answer: In Medieval Europe, knights pledged loyalty to vassals, who in turn pledged theirs to powerful lords, and serfs labored in the fields.
Explanation:
A rigid hierarchy refers to one where people who are born into a certain position in life, find it quite hard to move from it or rather one where there are different social classes and people had to be classified in one class for the system to work.
The system during medieval times was much like this. Social classes existed that determined a person's worth in society such as the knights, vassals, Lords and Royals. There was also the serfs who were considered the lowest in the hierarchy.
The statement is true.
As weird as it may sound, helium was indeed first discovered on the Sun, and after some time on Earth. The first evidence of helium was observed on August 18 1868, as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the Sun's chromosphere. This line has been detected by a French astronomer by the name of Jules Janssen during a total solar eclipse in Gantur, India.
Answer:
Q. 41. Basaltic Lava, Q.43. Basaltic magma Q.44. False
Explanation:
Basalt is a mafic extrusive igneous rock, formed by the rapid cooling of Mg and Fe rich lava, exposed at or near the surface of the earth. Thus forming about 90% of the surface lava on earth.
Shield Volcanoes emit lava or magma in the form of viscous basaltic lava. Highly explosive.
Greenland and Antarctica together constitute the 99% of the earth ice caps so, Greenland has about 80% cover as compared to antarctic 98% and both are depleting fast.
