Question 1 1 pts
The outer region of our solar system is comprised of primarily light elements (e. g.
hydrogen, helium, carbon, oxygen, nitrogen, etc.). Why aren't there as many of the
heavier (rock, mineral, & metal-forming) elements in the outer region?
O Outer solar system had TOO MUCH NUCLEAR ACTIVITY to form heavy elements.
O Outer solar system had TOO MUCH GRAVITY to form heavy elements.
Outer solar system was NOT HOT ENOUGH to fuse the heavier elements.
O Outer solar system was NOT COLD ENOUGH to fuse the heavy elements.
