If we space closer come the equator 보다 to either the phibìc or the southern Pole, approximately how rapid are we relocating with the rotation of Earth?
earths speed of rotation on axis, typical speeds the stars in neighborhood solar neighborhood relative come us, earths rate of change about sun, rate of ours solar mechanism orbiting center of milky means galaxy, speeds of an extremely distant galaxies family member to united state
From the reality that basically every galaxy is moving away from us and an ext distant galaxies are moving away from united state at a faster rate 보다 closer ones, us conclude that..
You are watching: Earth is made mostly of metals and rocks. where did this material come from
13) by studying remote galaxies in the 1920s, hubble made the complying with important exploration that 13) led us to conclude that the cosmos is expanding:
A) every galaxies external the Local group are relocating away indigenous us, and also the farther away they are, the faster they"re going.
