The moon may look as though it gives off light, but it does not. That is what Earth and Space Science is all about. This is something people had imagined for a very long time, in books and movies and stories grandparents told to their grandchildren. However, in the 1950s, … … Space Facts! Combining the information (data) gathered by a variety of robots gives us a broader and more in-depth The Earth and Space Sciences: Content Knowledge test is designed to measure the knowledge and competencies necessary for a beginning teacher of secondary school Earth and Space Science. But this hasn't always been the case. somewhere in space. Understandings 1. Our knowledge and understanding of our Earth and Solar System changes and/or expands as new discoveries are made.

Every part of space participated in it. The moon is made of rock. of orbits around Earth (as you’ll see in later chapters), they look far, far away. To cope with the growing complexity of scien- Robots gather different information (data) depending on their design and use. This congestion presents a higher potential for orbital collisions and increases the need for timely and thorough space situational awareness. Indeed, today space research is indispensable for a multitude of scientif-ic fields. Around Earth Earth has one moon. space environment nearest to Earth. Earth science is the name for the group of sciences that deals with Earth and its neighbors in space. The force of gravity is 1/6 that of Earth’ s. The gravitational pull of the Moon on the Earth causes ocean tides on the Earth. And, of course, the larger • Geology means “study of Earth.” Geology is divided into physical geology and historical geology. It looks bright when it reflects light from the sun.
