(b) The further comets are from the sun, the slower they travel; therefore, it spends longer at the further distance.…
A. Proposes that icy comets bombarded the Earth for more than a billion years, while its atmosphere was still thin, accumulating fresh water from space that filled the basins in the formative crust.…
Asteroids and Comets: Evidence suggests a second source of water for Earth’s oceans. During the time when oceans formed, many icy comets and asteroids from space collided with Earth. The melted ice from these objects added to the water filling Earth’s ocean basins.…
4. The formation of the solar system from a huge cloud of dust and gases is called the ______________theory (although some sources refer to this as a hypothesis). (Points: 2)…
This episodes of cosmos was a very interesting one. Neil Degrasse starts off with what was suppose to be the means of diversity between humans and animals and he speaks on the topics of natural selection, genetic drift and more to explain why there are so many different breed of creatures and why some are preferred compared to others in certain types of environments. He introduced us to a tree that contained all of the creatures that have been discovered by man, and he tells us the similar physical features that are shared amongst ourselves and those creatures. The part that fascinated me the most is the one that spoke on the topic of the development of eyesight, he used the example of sea creatures to display the complexity of eyesight development.…
2. Your 6th grader has read an article at school about life on other planets, and your child voluntered you to talk to the class about procaryotes and your opinion on whether there can be microbial life on other planets. In light of what you have learned from this chapter, develop an intelligent response for your to present to your childs class. (yes, this is an actual question, and base your response on the reading from this chapter and the web site and any other choices you wish to use!)…
Which of the following best explains why we can rule out the idea that planets are usually formed by near-collisions between stars?…
Terrestrial planets formed inside the frost line, where accretion allowed tiny, solid grains of metal and rock to grow into planetesimals…
Since ancient times, man has pondered over the great enigma about how our universe was formed. In earlier times we have answered this question through creationism, but with our burgeoning thirst of knowledge, we quench this thirst with science. Although we have a superior understanding of how our universe was formed, this question still remains. By sending Cassini to the f-ring of Saturn we can observe how planets form and interact with other matter in space, determine the definitive age of the rings and disprove pre-existing theories about Saturn as a whole.…
The nebular hypothesis explains how our solar system probably formed from a giant cloud of gases and dispersed solid particles.…
Spacecrafts have retrieved extraordinarily valuable information that has furthered the human race’s knowledge of what exists in outer space. However, spacecrafts and shuttles are extremely expensive to build and launch into space so they should be well taken care of. Sending a spacecraft to an asteroid is far better and safer than sending a spacecraft to a comet for quite a few different reasons. First, an asteroid is made up of less materials than a comet. Next, comets produce two tails when approaching the Sun. Lastly, an asteroid’s orbit is much more predictable than a comet’s orbit. With these characteristics, asteroids make a better object for spacecrafts to land on rather than comets.…
named after Gerald Kuiper, who predicted in 1951, as a hypothesis, that the shortperiod comets originate from a collection of material left over from the formation…
The formation of the solar systems started with the idea that a very large cloud of hydrogen gas and dust gets disturbed by something and starts to collapse into its center, the center heats up and becomes a proto-star, the center continues to collapse, under the pull of gravity until it gets hot enough to begin fusing hydrogen into helium and becomes a star on the “main sequence”. It is believe that for a system of planets to form around a star during cloud contraction the cloud must contain heavy elements. When a star ends its life, it explodes in a tremendous…
The Solar System and One Planet Presentation Nicole L Clawson SCI/151: Astronomy November 10, 2014 Jorge Espinosa Introduction Explain the formation of the solar system. Describe a cross-section of Earth with descriptions of its geology and atmosphere. Describe other terrestrial planets’ geology and atmospheres. Describe other kinds of objects sub as asteroids, comets, etc that are found in the solar system.…
Do you believe that there is life on other planets? Better yet, do you believe that there is another planet that looks like earth? As far as I can remember, there has always been the question of “is there life in outer space? I remember being in grade school wondering if there were humans or aliens on other planets and if they were trying to communicate with us. Around January 1986 the Space Shuttle Challenger exploded during takeoff in front of the entire world. As a teenager, this event was tragic and amazing at the same time because I felt that we were on our way to discovering new planets, solar systems, and other life forms. This tragic event was the start of my interest in outer space.…
