Answer:
Titan
Explanation:
It is the only moon in our solar system known to have a substantial atmosphere, which is mostly nitrogen like Earth's. This moon is the largest of Saturn's Moons.
Hope this helped! :)
Answer: Changes in Earth-Sun relationships, namely Earth's orbit around the sun, axial rotation, and axial tilt
Explanation: Milankovitch cycles refer to changes in the Earth-Sun relations because of the earth's orbital eccentricity that the Earth circles the Sun. The shape of the Earth's path around the sun is eccentricity, due to the constant change of the orbital form within the limits of 0 to 5% ellipticity. In addition, these cycles occur not only due to eccentricity, but also due to axial rotation and axial tilt. All this has an employer of climate change on Earth due to the change in the amount of sunlight. These changes should be understood as very long-term, for example, the Ice Age cycle is associated with changes in the amount of sunlight, and due to changes of Earth's orbit. This means they are important as long-term changes.
The 2 main gasses which are found in the earth's atmosphere are C. Carbon dioxide and Oxygen.
Hello there!
Greenhouse agriculture is a place like a house where the plants grow under controlled micro environment.
-------------------------------
For example:
I am not sure if all Walmart has it but there is a Walmart near me and they have a greenhouse agriculture. They have plants there for people to buy. Of course it is not big like the other real greenhouse agriculture but it is similar.
I hope this helps!
Answer:
The albedo temperature for Mars and Venus are 210K and 184 K respectively.Mars albedo temperature is closer to its black body temperature such that the Venus has more albedo.Thus there is a chance that Mars would have had life in their history.
Explanation:
The albedo temperature is given as
![Te =\left [\dfrac{L(1-a)}{ (16\pi \sigma D^2}\right]^{1/4}](https://tex.z-dn.net/?f=Te%20%3D%5Cleft%20%5B%5Cdfrac%7BL%281-a%29%7D%7B%20%2816%5Cpi%20%5Csigma%20D%5E2%7D%5Cright%5D%5E%7B1%2F4%7D)
Here
L = Solar luminosity = 3.846*1026 W m-2 K-4
D = distance from Sun
σ = the Stefan-Boltzman constant = 5.6704 * 10-8 W
a is the albedo constant whose value for Mars is 0.250 while for Venus it is 0.900
So the albedo temperature is given as
Venus: 184 K
Mars: 210 K
The black body temperature is given as
![Te =\left [\dfrac{L}{ (16\pi \sigma D^2}\right]^{1/4}](https://tex.z-dn.net/?f=Te%20%3D%5Cleft%20%5B%5Cdfrac%7BL%7D%7B%20%2816%5Cpi%20%5Csigma%20D%5E2%7D%5Cright%5D%5E%7B1%2F4%7D)
By substitution of the values, the black body temperature for Venus and Mars are as
Venus: 327 K
Mars: 225 K
Mars albedo temperature is closer to its black body temperature such that the Venus has more albedo.
Thus there is a chance that Mars would have had life in their history.
