it might help if you think of… Remember we talked about the two classes of planets in our solar system? And how they differ in composition…[reviewing] the terrestrial planets like Mars and Earth…composed largely of rocks and metals, and the large gas giants like Jupiter. Well, the ...
What is marine geology? Geology: The lithosphere is composed of the upper mantle and the crust and it is the outermost shell of a terrestrial planet or natural satellite. The study of the solid features on the Earth, the composition of rocks and the processes which can cause change are stud...
What is the main optical element of a refracting telescope? What does the temperature and composition of a star tell us? What makes up star cluster? How do scientists classify stars? Name the gases that make up most stars? What is the main optical element of a reflecting telescope?
Examining the CMB also gives astronomers clues as to the composition of the universe. Researchers think most of the cosmos is made up of matter and energy that cannot be "sensed" with our conventional instruments, leading to the names "dark matter" and "dark energy." It is thought that onl...
Although we do not know the precise composition of the early atmosphere, there has been enough progress made on this subject in recent years that it is possible to say with some certainty that the methane-rich composition envisioned by Oparin, and the methane-ammonia-hydrogen mixture used by Mi...
How abundant is hydrogen in the Earth's crust, the ocean, and the atmosphere? What moon in our solar system has a substantial atmosphere? Which planet captures atmosphere gravitationally? Which of the terrestrial planets has the highest surface temperature? What is the composition of the atmosphere...
Things that make life on Earth possible: The Sun is a G-type main-sequence star (G2V) based on spectral class and is informally referred to as a yellow dwarf. It is stable (even less active compared to its siblings), long-lasting, and metal-rich. Image: NASAAt the heart of Earth...
Asteroids are the rocky remnants of material leftover from the formation of the solar system and its planets approximately 4.6 billion years ago. The majority of asteroids originate from the mainasteroid beltlocated between Mars and Jupiter,according to NASA.NASA's current asteroid count is over 1...
What is Astronomy? Transcript Astronomy is a broad scientific topic that includes all objects beyond the Earth, as well the Earth itself. The word astronomy has Greek roots meaning “the laws of the stars.” Astronomers study everything from the soil composition of Mars to the fate of the ...
