The obliquity (axial tilt), precession (wobble), and the eccentricity (how close to being circular) of the Earth’s orbit, comprise the Milankovitch cycle. These three factors affect the amount of heat energy from the sun (solar heat) directed to Earth, influencing climactic changes and patterns.
The tilt of the axis mainly affects the amount of solar heat each hemisphere receives. The greater the tilt, the more solar energy is directed at the northern hemisphere. Along with precession, they also affect the length of days and nights experienced by certain parts of the Earth.
The eccentricity of the orbit affects the distance of the Earth to the Sun during its revolution in orbit. The orbit is an elliptical path followed by the Earth, with the Sun not exactly at the center. Thus, there is a time when the Earth is closest to the Sun (perihelion) and this allows the Earth to experience radiation the most. On the other hand, there is also a time when Earth is farthest to the Sun (aphelion). This difference in distance creates a heat exposure retained by the Earth. From the time of perihelion it absorbs so much solar energy and is gradually expended revolving but at the same time still absorbing solar heat – hotter global temperature
.
If the orbit was more circular, the distance of the Earth to the Sun will always be the same at any point in the orbit. Thus, allowing equal exposure to the Earth at all times. There will be no point in time in which the Earth will absorb so much heat. This will cause a cooler global temperature compared to the elliptical orbit.
I thinks its a layer of soil with characteristic properties, sorry if its wrong I'm a beginner
Answer:
The lunar phases gradually change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. The Moon's rotation is tidally locked by Earth's gravity; therefore, most of the same lunar side always faces Earth.

Answer:
Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!
Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.
Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.
The right answers are:
create two identical cells ==> mitosis
create four non-identical cells ==> meiosis
create haploid cells ==> meiosis
creates diploid cells ==> mitosis
occurs in all cels other tha gametes ==> mitosis
occurs in all cells related to sexual reproduction ==> meiosis
