I will awnser the first question. the angle of the earth dose effect the temp of the earth. if it is angled tired the sun it gets hotter and if it is angled away from the sun it gets cooler.
Meridians are perpendicular to every latitude<span>. ... All the other </span>longitudes are measured<span>, and named after the angle they make with respect to the center of the Earth from the intersection of the Meridian and the Equator. Since a sphere has 360 </span>degrees<span>, the Earth is divided into 360 </span>longitudes<span>.</span>
I believe the answer is E, but i'm not 100% percent sure
