Answer:
The best answer to the question: With the discovery of magnetic reversals, there was evidence that:___, would be: the sea floor could create new continental crust.
Explanation:
The theory of sea floor spreading, which came from the studies of how continents formed, and the general mechanics of geology and geophysics, led scientists, since the 1960´s to understand how continental crust, and new land, is formed from the Earth´s lava mantle and the core. This sea floor spreading has been defined as the process during which, as mid-ocean ridges, which delimit two continental plates, move apart, weakening the crust, magna is able to pour through the ridge and form new crust. In relation with magnetic reversals, it must be said that this new crust that forms as lava pours forth will be magnetically charge at the time of its deposition on the surface, and as it cools down, it will store in it the magnetic charge to which it was exposed in the mantle before it was poured forth. As such, magnetic reversal shows that the earth has changed polarity throughout time, polar reversals, and these reversals have been proven through rock evidence that has been present in the ocean ridges, almost like records of the magnetic event.
Answer: C they bring heavy rainfall in summer months
Explanation:
The formula for population density is Dp= N/A, where Dp is the population density, N is the total population, and A is the land area covered by the population. For human populations, A is typically expressed as square miles or square kilometers.
The population density of a country or city or other place is a number showing how crowded that place is. ... For example, France has a population of 60,561,200, and an area of 551,695 square kilometres, so its population density is about 109.8 persons per square kilometre.
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.
