Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward , in prograde motion .
At the equator, the solar rotation period is 24.47 days. This is called the sidereal rotation period, and should not be confused with the synodic rotation period of 26.24 days, which is the time for a fixed feature on the Sun to rotate to the same apparent position as viewed from Earth (the Earth's orbital rotation is in the same direction as the Sun's rotation).
By astronomical convention, the four seasons are determined by the solstices (the two points in the Earth's orbit of the maximum tilt of the Earth's axis, toward the Sun or away from the Sun) and the equinoxes (the two points in the Earth's orbit where the Earth's tilted axis and an imaginary line drawn from the Earth to the Sun are exactly ...
The Sun before sunrise is called Savitr, and after sunrise until sunset it is called Sūrya. [4] Savitr is venerated in the Rig Veda , the oldest component of the Vedic scriptures. He is first recorded in book three of the Rigveda; (RV 3.62.10) later called the Gayatri mantra .
This means that dynamo theory was originally used to explain the Sun's magnetic field in its relationship with that of the Earth. However, this hypothesis, which was initially proposed by Joseph Larmor in 1919, has been modified due to extensive studies of magnetic secular variation , paleomagnetism (including polarity reversals ), seismology ...
The word Sudarshana is derived from two Sanskrit words – Su (सु) meaning "good/auspicious" and Darshana (दर्शन) meaning "vision".In the Monier-Williams dictionary the word Chakra is derived from the root क्रम् (kram) or ऋत् (rt) or क्रि (kri) and refers among many meanings, to the wheel of a carriage, wheel of the sun's chariot or metaphorically to the ...
Sea water, in theory, could be used to help a fire. But, its salty components can do more harm than good, which is why firefighters typically avoid using it unless absolutely necessary.
A sunshower, or sun shower, is a meteorological phenomenon in which rain falls while the Sun is seen shining. [1] A sunshower is usually a result of winds associated with a rain storm sometimes miles away, blowing the airborne raindrops into an area where there are no clouds.
