The precession of earth's rotational axis causes the location of the North Celestial Pole and South Celestial Pole, Vernal Equinox and Autumnal Equinox, Summer Solstice and Winter Solstice to change.
The Sun and Moon's gravitational pull on Earth's equatorial bulge is what causes precession. The north and south celestial poles are two distinct locations that appear at opposing ends of the Earth's axis of rotation as it is projected into the sky. These points create circles in the sky due to precession. The Vernal Equinox, which is the point at which the celestial equator and ecliptic meet close to where the Sun is in the Northern Hemisphere Spring, serves as the celestial longitude zero point. The Autumnal Equinox occurs at the other point where the Celestial Equator and the Ecliptic cross. The durations of day and night are equal when the Sun is at one of the equinoxes.
The summer solstice is the longest day of the year and the winter solstice is the shortest day of the year in each hemisphere. The June solstice, when the North Pole is tilted closest to the Sun and the Sun's rays are directly above in the Tropic of Cancer, ushers in summer in the Northern Hemisphere. Winter officially begins on December 21st, when the South Pole is tilted closest to the Sun and the Tropic of Capricorn receives direct sunlight. On these days, the Sun's rays will be farthest north or south from the equator in the sky.

Imagine you are reading a book for school. You need to find important details that you can use for an assignment. However, when you begin to read, you notice that the book has very little punctuation. Sentences fail to form complete paragraphs and instead form one block of text without clear organization. Most likely, this book would frustrate and confuse you. Without clear and concise sentences, it is difficult to find the information you need.
For both students and professionals, clear communication is important. Whether you are typing an e-mail or writing a report, it is your responsibility to present your thoughts and ideas clearly and precisely. Writing in complete sentences is one way to ensure that you communicate well. This section covers how to recognize and write basic sentence structures and how to avoid some common writing errors.
Components of a Sentence
Clearly written, complete sentences require key information: a subject, a verb, and a complete idea. A sentence needs to make sense on its own. Sometimes, complete sentences are also called independent clauses. A clause is a group of words that may make up a sentence. An independent clause is a group of words that may stand alone as a complete, grammatically correct thought. The following sentences show independent clauses.

geologic studies suggest that the outer layers of earth were active in the process of plate tectonics by at least
Geologic studies suggest that the outer layers of earth were active in the plate tectonic process by at least 1.5 billion years ago.
Since the nature of plate tectonics, the origin of the process is obscured: Old oceanic crust is destroyed in subduction zones as new crust is created in spreading centres. It is difficult to determine when active plate tectonics began because of how effectively the planet's surface recycles, with the majority of oceanic crust being less than 200 million years old and very little continental crust remaining from Earth's early history.
Many scientists believe that plate tectonics began, in one form or another, around 3 billion years ago. However, some believe it may have begun as recently as 1 billion years ago or even earlier. Both the surface and the atmosphere of the Earth are shaped by plate tectonics. Large temperature fluctuations caused by too much or too little greenhouse gas are tempered by the release of volcanic gases and the formation of new silicate rock, which absorbs significant amounts of carbon dioxide from the atmosphere.

Plato and his pupil Aristotle taught that the earth is stationary and at the center of the universe with the sun, the moon, and the planets moving around the earth in perfect circles
Two eminent thinkers, Plato, and his pupil Aristotle held the view that Earth was the center of the universe in the fourth century. The geocentric theory is the name given to the notion that Earth is at the center of the cosmos. Any theory of the solar system's structure that places the earth at its center is called a geocentric model. Ptolemy of Alexandria's geocentric model was the most advanced. Aristotle thought that only humans existed on Earth and that they were the only species in the cosmos.

Isolated submarine volcanic mountains with a vertical relief of greater than 1000 meters are called?
Isolated submarine volcanic mountains with a vertical relief of greater than 1000 meters are called- Seamounts
Underwater mountains known as seamounts rise hundreds or thousands of feet above the ocean's surface. Typically, these are extinct volcanoes that produced lava heaps when they were active, which occasionally caused the ocean's surface to break.
Seamounts are frequently discovered close to the tectonic plate borders and mid-plate regions close to hotspots. As plates separate along mid-ocean ridges, magma rises to fill the spaces. Oceanic crust is forced toward the Earth's hot center around subduction zones where it melts and forms magma that rises buoyantly to the surface and explodes to produce volcanoes and seamounts.

The crust, mantle, and core are the three layers that make up the earth. Based on the behaviour of seismic waves and laboratory experiments, geologists can distinguish between them. The densities of each stratum provide the basis for these divisions. Minerals and solid rocks make up the crust.
The mantle, which lies below the crust, is composed primarily of solid rocks and minerals with some pliable regions of semi-solid magma. There is a heated, dense metal core in the center of the Earth. The crust and upper part of the mantle make up a unified geologic structure known as the lithosphere, and the layers of the Earth are continually in contact with one another.
