C! is your correct answer!
I wanna say earth's surface
<span>Energy produced in the center of the sun
flows out through the sun's layers in different forms, including visible
light. The sun's interior generally becomes cooler and less dense as
you move away from the center. </span><span>Rising currents of hot gas in the convection zone carry energy toward the sun's surface.</span>
Answer:
Stream gradient refers to the slope of the stream's channel .It is the vertical drop of the stream over a horizontal distance.
Explanation:
Gradient is the slope or steepness of a stream channel. It affects the stream's velocity because the steeper the gradient is the greater the velocity due to gravity.
Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form the sun.
