A large rift valley can be found along the east coast of Africa. It has been slowly widening over time, and it is now wide enough to contain many large lakes. Which of these best explains the slow widening of this rift valley over time?
Group of answer choices

Earth's rotation

wind and water erosion

the Moon's gravitational pull

lithospheric plate movement

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

this may not be entirely correct but let me know.

a is the answer to this question
