Answer:
Its given as below.
Explanation:
Mantle convection is a type of current that raises from the mantle plumes with lava or magma and its rising lava reaches the earth through volcanic eruption and further through the burning of plates inside the mantel, it is directly connected with at of the plates on earth as its due to this effect that the ring of fire is dotted by earthquakes of all types. The Hawaiian volcanoes are on this line also thus are highly explosive and viscous lava flowing from vents, the zone of most active volcanoes.
Answer:
Sidereal Time is the shortest time of earth and Synodic time is longest time of the sun.
Explanation:
<u>shortest to the longest time.
</u>
- Sidereal day and one rotation of the earth on its axis.
- Sidereal month and one full orbit around the earth.
- Synodic month and one full cycle of the moon.
- Solar day i.e Earth rotation on its axis so that the sun appears same on the sky.
As sideral refers to the events that occur on the same day with 23 hours 56 minutes 4.091 sec, and synodic day refers to the 24 hours and 2.5 ms aligned to astronomical bodies. Each synodic day the gradual motion is one degree eastwards. (360 degrees per year.)
The solar day is just one complete solar day. Time is calculated based on sun positioning of the solar clock i.e 24 hr format and the mean solar time is 12 hours.
Solar time does include the moon phases as this phenomenon is limited to the sidereal rotation of the earth on its axis. Aphelion and Perihelion are caused by the earth's rotational effects towards the sun being exposed at the time of day.
Answer:
D. the book is in equilibrium
Explanation:
The book does have the force of gravity exerted on it, but it is able to rest on the table because the force of gravity is countered by the force of the table pushing up on the book.
