NASA is hoping that the hard-working little rover will survive the Martian Winter.

1 reason why mars has such extreme seasons with drastic temperature variations is because it a tilt that faces the sun for long periods of time creating the extreme seasons one year on mars take 687 earth days. that's why the seasons are so much longer.

ReplyDeleteTwo reasons for why Mars has such extreme seasons with drastic temperature variations are that it is farther away from the sun, causing it to have colder seasons than we do, and it has a more eccentric orbit. The different orbit of Mars causes the darastic temperature variations.
ReplyDeletethe moon keeps us in place and makes us tilt because of the gravity of the moon pulls on us and it makes sure we do not go out of orbit
ReplyDeleteIn picture 1 the Earth looks very detailed and you can see what the Earth clearly looks like from a far distance, like in space. It looks like the grass isn't as green because it is winter in North America, because of our tilt the Sun is not directly hitting us.
ReplyDeletethe different orbit makes the drastic tempatures and it is farther away from the sun and that makes the tempatures very cold.
ReplyDeleteThe moon is really the only reason the Earth exists and because of its tilt we have seasons and stuff and the moons gravity pulls on the Earth to keep it in orbit.
ReplyDeleteOne Reason is because Mars has a thin atmosphere and the thin atmosphere will probably make drastic changes. Another reason could be it doesn't have a moon like Earth, and the last one is the length of the Mars year (686.97 days)
ReplyDeleteOne reason why Mars has drastic temperature changes is because of its eccentric (or Kepler) orbit. Because of this orbit, Mars revolves around the sun in an oval shape. At times, Mars, in its oval orbit, is closer to the sun, enabling it to get to 65 degrees F. At the ends of the oval, it is even farther from the sun than if it's orbit was a circular shape, making it get to very cold temperatures.
ReplyDeleteAnother reason why Mars can get extreme cold temperatures is because of its distance from the sun. Mars is farther from the Sun than Earth, making the sun's heat/light less intense. This lack of heat makes Mars very cold.
1) There is no tilted axis to Mars, therefore the rotation and revolution of its orbit around the Sun is way more severe all over the planet than Earth's orbit, due to excessive sunlight on one side of the planet at all times. There are no REAL seasons, yet there are climate changes because of it.
ReplyDelete2) It's farther away from the Sun than Earth is, making nights and winters extremely cold, much colder than Earth's, and the days and summers can get pretty hot.
One reason that Mars has a wide range of temperature is that Mars is about 78 million kilometers farther away from the sun compared to the distance between the Earth and the sun (Mars= 228million kilo) (Earth= 150million kilo).
ReplyDeleteAnother reason why Mars has a wide range of temperature is that Mars has two asteroids instead of an actual moon to control the Mars... If Mars did have a Moon then there could be complex life on Mars...
Mars is suffering from reverse global warming. By how the core has stopped creating a magneic field that prevents solar heat from cooking the martian planet. So the heat will be extreme or the fact that the atmosphere is so thin that the cold space surronding the solar system seeps in and chills the planet.
ReplyDeleteMars has such extreme seasons for two reasons.
ReplyDelete-Unlike Earth, Mars doesn't have a moon to stablize it during its rptation.
-Mars is also farther from the Sun, compared to Earth. This gives it colder temperatures which combined with the fact that it has no atmosphere to absorb sunlight, create drastic temperatures in both ways
-Sam Gravois
One reason Mars has such extreme seasons with drastic temperature variations is because of its Kepler orbit that makes an oval orbit around the sun changing the temperature to higher why its closer and lower why its further away from the sun. The second reason is because Mars doesn't have a moon.
ReplyDeleteThe first reason is because Mars does not have a moon like ours , with a gravitational pull . This means that Mars is unstable with its rotation , which causes drastic climates all over the planet .
ReplyDeleteThe second reason is because Mars is farther from the Sun than Earth is , which means two things :
1) its temperatures are automatically colder , with no atmosphere to absorb heat from any light source (Sun) which causes major temperature changes
2) its too far away from the Sun to get a gravitational pull , which is another reason why the planet is unstable .
^^ 2 reasons why Mars has drastic climate/temperature changes.
-Tessa
1) Mars doesnt have a moon like us that has a gravitional pull, because of this mars moves differently and has wibble woubble rotaintion not steady like the earth.
ReplyDelete2)It has a more than double orbit around the sun making the tempures way colder than Earths.
