Answer:
Uses symbols
Are a good resource for long-range planning
Are used by meteorologists to create other maps
Explanation:
<span>water vapor molecules clump together faster than they are torn apart from their thermal energy</span>
We need to assume that the orbits are circular; this is a very good approximation and do not hesitate to adopt it. We need then to consider the basic equation of circular motion that relates centripetal acceleration, angular velocity, mass, radius and force:

. We also have the basic equation of Newton, F=ma. By checking, we see that for each planet we have that a=v^2*r where v is the angular velocity. v=

where T is the orbital period, hence we have that a=

. Denote with the index 1 the Earth case and with 2 the Mars case. We have then that

. Substituting the known values in a calculator, we get the result: the centripetal acceleration of earth is 2.32 times greater than that of Mars.
Answer: Option (A) and (C)
Explanation: In case of slow sea floor spreading, the magma within the crust doesn't get proper way to exert the force upward because of its slower rate of spreading. Due to this, rifting occurs along the mid oceanic ridge.
Due to continuous rifting, it forms a valley known as the rift valley. This rift valley lacks in ridge and is comparatively smooth compared to a fast spreading sea floor, in which the topography appears to be rough and ridges are formed.
Thus, the statements that are true are option (A) and (C).
