Answer:
Question 1: getting there
Mars- between 150 and 300 days depending on where mars is in relation to the earth, the speed of the launch, and the exact travel path that will be taken
Uranus- about 9 and a half years
Question 2: weather
Mars- the atmosphere is completely thin, and an extremely cold planet, with an average temperature of around -80°
Uranus- has very strange seasons due to its tilt, has a surface temperature of about -300°F, strong winds, and sometimes clouds made up of methane ice crystals
Question 3: clothing
Mars and Uranus- both mars and Uranus are unsuitable for humans, you would most definetly need a full body space suit such as the Z-2 Spacesuit created by NASA
you can answer the rest based off imagination and Google for facts
Answer:
Seafloor spreading results from intense activity in the upper mantle which cracks the crust and pushes it away.
Explanation:
Seafloor spreading is a process that was first noticed by Alfred Wegener and was used by him in his theory of plate tectonics. There are three types of plate boundaries; convergent boundary, transform boundary, and divergent boundary. The last one is the one where seafloor spreading occurs.
The convection currents in the mantle are the process that breaks up the crust and move the tectonic plates, and when there is higher activity than usual at some place it results in break up the crust of an already existing tectonic plate. Basically, magma rises at a higher rate and pushes through the crust, in this case, the oceanic crust, and it manages to gradually break through it and come out on the seafloor. By doing so, the magma and the pressure from below are pushing the two now divided parts of the plate. As the space between the two different parts becomes larger and large the density of the crust becomes smaller and smaller so more and more magma rises through. The magma quickly solidifies on the ocean floor and piles up, thus creating an underwater mountain range known as a mid-ocean ridge.
Our planet, Earth appears blue due to the mass amounts of water and lacks on its surface.
If you add the two lengths on the left, you can figure out that one side is 100 units and the base is 50. In the smaller triangle, the ratio of base length to side length should be the same. If the big triangle is 50:100, then the small triangles base should be 1/2 it’s side. 1/2 of 60 is...
30 units
Hope this helps :)
One reason is that the plates float on a hot boiling mentle. when the heat rises and the mentle expands the plates above it also moves.
the other reason is that the plates themselves move.plates have warmer inner sides that tend to rise. and colder outer side that tends to sink. this tug of war between the hotter and colder sides of the plate also helps them move.
