How does Earth's atmosphere compare to the atmospheres of Mars and Venus?
Okay first of all mars does not have life 2ndly mars is the 4th planet earth is the 3rd planet mars is mostly red and earth is mostly blue there is some but there are alot moreThe difference between them is that Earth is larger and Mars does not have qualities for life to sprout.71% of Earth's surface is water. Mars has no liquid water, but the Phoenix Mars Lander scooped up soil and ice.Mars gravity is 2.7 times less than that of Earth. Mars has 2 moons and it's atmosphere is 95% CO2 with a tiny bit of nitrogen, argon, oxygen, and carbon monoxide.Earth has 1 moon and has a lot of nitrogen and some oxygen and others (tiny bits of argon and carbon dioxide).(Also, our deserts are hot in the daytime and cold at night. Mars's deserts are freezing and airless.)The biggest difference is that Earth has advanced life forms, Mars does not.Mars is smaller than earth with less gravity. It also has a very thin CO2 atmosphere where Earth has a Nitrogen Oxygen atmosphere that is much thicker. Mars is also very cold while Earth is warm.* Earth is almost twice the diameter of Mars.Nearly 70% of Earth's surface is liquid water, while Mars has none.The sun warms the Earth to more the 100oF; on Mars the temperature barely goes above the freezing mark.Earth has an atmosphere breathable by humans. Mars has virtually none, and it is composed almost entirely of toxic gases. IIRC, Mars is about 1 1/2 time farther from the sun than Earth; and is about 1/2 the size, and 3/4 the density.It's surface is largely iron oxide, which gives it its reddish color. There is no liquid water (there is ice at the poles). Because is it has a much thinner atmosphere, and is farther from the sun, it is much colder.Astronmers speculate that Mars was once much closer to the sun and was more "earthlike," but gradually moved farther away, resulting in its present state.
How far is each planet from earth?

What is 68 percent of the us electrical energy produced by?
Coal.
How old was Picasso when his last kid was born?
Oh, dude, Picasso was like 68 years old when his last kid was born. Can you imagine changing diapers at that age? Like, props to him for keeping the creativity flowing even in his golden years.
How far away is the farthest satellite?
The earth is a planet. An earth satellite is an artificial satellite that orbits the earth A geostationary satellite is an earth satellite that orbits at a height (approximately 22,000 miles) precisely determined to ensure that the satellite remains over the same spot on the earth's surface at all times, thus appearing from the earth to be stationary in the sky.
What layer of the earth is 68 percent?
The mantle is the layer of the Earth that makes up approximately 68% of the Earth's mass. It is located between the Earth's crust and core and consists of solid rock that can flow slowly over geological time scales.
Why if a man weight 180 pounds on Earth he would weight 63 on Mars?
A person's weight on Mars would be 38% less than his weight on the Earth. This is because Mars's gravity is 38% weaker than that of the Earth, so Mars pulls on the person with less force, resulting in lower weight of the person. Edit: 38% of 180 is 68.4. So that doesn't exactly fit the question. However I agree with the "38%" value, so perhaps the question meant "68" not "63".
What is the Mass of 68 kilograms?
68 kilograms
What is the volume of a mass of 68 grams?
The answer to that depends on the density of the substance in question.For instance the volume of 68 grams of Lead would be smaller than the volume of an equivalent mass of gaseous hydrogen.
What is the weight of 1000 us dollars in quarter?
The mass of a US quarter is 5. 67 grams. 4000 of them would total 22. 68 kilograms, which on Earth is equal to about 50 pounds.
How much of earth's land surface is located north of the equator?
less tan 1/2 Excluding Antarctica approximately 78 percent of Earth's land mass is above the Equator
What is the tenpreture on Mars?
-220 through 68 F
Percentage of land mass in eastern hemisphere?
Approximately 68% of Earth's land mass is located in the eastern hemisphere. This includes continents such as Asia, Europe, Africa, and Australia.
Find the density of a substance that has a mass of 31 g and a volume of 68 cm3?
Density equals mass divided by volume. so 68 cm3 / 31 g = 2.2 g/cm3 would be the answer...2.2 g/cm3
What is the warmest it has ever been on mars?
The warmest it gets on Mars in the summer time is 68 degrees Fahrenheit
How hot is mars crust?
Mars does not have a molten core like Earth, so its crust doesn't reach high temperatures like terrestrial crust. The average temperature of Mars' crust is estimated to be around -80 degrees Celsius (-112 degrees Fahrenheit).
How many months does it take for eat and mars to be close?
68 years
