Answer:

B. As new rocks are formed along mid-ocean ridges, older rocks are pushed down deep into the Earth into ocean trenches.

<h2>Why is the Earth not getting larger if the sea floor is slowly spreading?</h2>

Mainly due to the Atlantic experiencing seabed expansion. The sea bottom is subducting, or moving underground, in the Pacific. This is how the Earth's tectonic plates and geological activities function. The top side of the mantle travels to the bottom at one end and to the top at the other, similar to a conveyor belt. This explains why there are volcanoes, why continents drift, and why our planet's surface is continually changing over the span of millions of years.

Therefore, the planet is not getting bigger because its surface is constantly recycling itself.

Answer:

The given blank can be filled with corona.

The Moon moves in between the Earth and the Sun in a solar eclipse. When this takes place, a segment of the light of the Sun gets blocked. During a total eclipse of the Sun, the corona of the Sun can be witnessed shining in all the orientations surrounding the Moon. The only time when the corona of the Sun can be witnessed is during a total solar eclipse. Colorful lights from the chromosphere of the Sun and the solar prominences are also visible at the time of a total solar eclipse.

A population's emigration in one month totaled three individuals. During the same period, immigration was 17 individuals. Natali
Ratling [72]

There was no net change in the given population. The size of the given population remains unchanged.

The explanation behind this is that if we consider the given values-

Emigration- 3

Immigration- 17

Natality- 12

Mortality-26

Therefore,

The overall effect on the population will be=

(Emigration+ Mortality) - (Immigration + Natality)

= (3+26) - (17 + 12)

=29-29

=0

Here the emigration means the number of people who have migrated from the population. Mortality refers to the number of deaths in a given population. Immigration is the migration of people into the population and natality is the overall number of births that have taken place in a population. Therefore there is no net gain or loss in the given population. This exerts no effect on the population keeping it unchanged.
