Which of these statements is true about heating up air in the lower atmosphere? It occurs mainly through radiant energy.
It occurs through convection from Earth.
It happens to a different extent over land and water.
It takes place through conduction between the sun and air.

it takes place through conduction between the Sun and Air

Explanation:

the sun helps heat it up for radiation and conduction is what keeps the air warmer

coordinates of r(b,c)

slope of nm is 0.

step-by-step explanation:

the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

the midpoint of the line segment nk is given by

∴r(b,c)

the slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

slope of rs is

hence

coordinates of r(b,c)

and slope of nm is 0.

i would love to you but i cant see a picture. i see that you already told someone before that i wont let post pictures on well i can kinda of you. posting pictures on here with your question is so much easier if your posting them on the app on your phone. if your trying to post a picture on a computer what you have to do is find out the name of the painting or equation, and once you've got that go to google type in the name and ta-da! and then last but not least you have to copy it. at the bottom of where you typing out the question you sould have this thing that looks like a paper clip and hit that and it should let you add it on here.

i hope this

have a great day
