Newton’s 1st law of motion states that a moving object will go in a straight line unless an outside force changes this motion. what outside force prevents supply planets from moving in a straight line into space? -gravity - meteorite impacts - supernovas -nuclear fusion

i think that is is gravity becasue gravity pulls the planets

I would say that gravity from other planets and the sun prevents supply planets from moving in a straight line into space.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
