Light travels from the sun to the earth, a distance of 144,000,000,000 meters, in 480 seconds. calculate the approximate velocity of light in the direction it travels toward the earth.

144.000.000.000÷480

=300.000.000 m/s

=300.00 km/s

explanation:

it dosn't have red,yellow,green,blue,indigo,violet,or purple

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
