James is a scientist who is working on finding an answer to a question about solar eclipses; however, he doesn’t have enough time or data to test all the possible answers to his question. Based on this, James is using specific studies and calculations in an effort to find answers that are close to, or an approximation of, a correct answer. What are these approximation answers that James is looking for called? intervals astrometry estimation clusters

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.

explanation:

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
