Humans have long considered whether or not there is life somewhere else in the universe. our movies and books have been filled with the ideas of martians and other alien creatures. considering
what you know about earth's characteristics compared to the other planets, and earth's place in the universe, what do you think? do you believe there is lite somewhere else in the solar system?
what about somewhere else in the milky way? how about in other galaxies?
The Earth's seasons are not caused by the differences in the distance from the Sun throughout the year (these differences are extremely small). The seasons are the result of the tilt of the Earth's axis.
The Earth's axis is tilted from perpendicular to the plane of the ecliptic by 23.45°. This tilting is what gives us the four seasons of the year - spring, summer, autumn (fall) and winter. Since the axis is tilted, different parts of the globe are oriented towards the Sun at different times of the year.
Summer is warmer than winter (in each hemisphere) because the Sun's rays hit the Earth at a more direct angle during summer than during winter and also because the days are much longer than the nights during the summer. During the winter, the Sun's rays hit the Earth at an extreme angle, and the days are very short. These effects are due to the tilt of the Earth's axis.
The solstices are days when the Sun reaches its farthest northern and southern declinations. The winter solstice occurs on December 21 or 22 and marks the beginning of winter (this is the shortest day of the year). The summer solstice occurs on June 21 and marks the beginning of summer (this is the longest day of the year).
Equinoxes are days in which day and night are of equal duration. The two yearly equinoxes occur when the Sun crosses the celestial equator.
The vernal equinox occurs in late March (this is the beginning of spring in the Northern Hemisphere and the beginning of fall in the Southern Hemisphere); the autumnal equinox occurs in late September (this is the beginning of fall in the Northern Hemisphere and the beginning of spring in the Southern Hemisphere).
Nearly everyone enjoys the change of seasons on Earth – from winter to spring, from summer to fall. ... Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun
Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface.
The interior of Mars is probably solid.
The Earth's magnetic dynamo is generated by a current in the interior of the planet that is a result of the eddies that form thanks to the outer core being molten.
Since Mars is a smaller planet and is located twice as far from the Sun as Earth, it cooled faster and likely no longer has a molten or semi-molten interior. The cooling of the interior of the planet would have shut off the magnetic process and could explain why the modern Martian atmosphere is so tenuous.
The interior of mars is rigid
To produce the magnetic field of the earth, the outer core is fluid and constantly moving.The outer core is made up of metalsThese metals are rich in iron and nickel and some other elements. During the early formation of the earth, these minerals differentiated into this layer of the earth based on their density. But the outer core region is molten and fluid. The movement of these materials is responsible for the production of the geo-magnetic field that makes the earth behave like a bar magnet.
Mars has no magnetic field and we can suggest that its interior is rigid and solid.
Hope this helps you...
There are also different types of Earthquake waves such as P. Waves, S. Waves, and Surface Waves
-P.Waves: "Primary" or "push-pull" and it travel faster than other waves
-S. Waves: "Secondary" or "side-to-side" and it leaves the epicenter at the same time as the P. Waves but travel slower and it reaches the location after the
-Surface wave is the strongest and it only travel on the crush. it is a combo of the P. and S. waves
