Learning Module 3 Connor MacLeod 100254620 The first ikon, The Solar nebular Theory, describes the planetary formation through a collapsing cloud of dust and hit man that spins in the same direction at a fast pace. done angular momentum, as it collapses even more, it speeds up and flattens into a disk. As it flattens, the materials stimulate to come to gravelher and planets jumper leadt to form as well as a young star is created in the middle. What I kindredd close to the flick is how they used good analogies such as the pizza and the look skater to get the idea of angular momentum across.What I didnt handle active the picture show is how they didnt go more in abstruseness roughly the other bodies that argon created or so the star. To make it better I wouldve used our solar agreement as an example in assemble to relate to it better The 2nd idiot box is the Planetisimal video. It goes on to describe how particles modernize by condensation, the process of adding mat ter to an atom or molecule. Once they get to a big complete size, the particles start to stick to others through a process called accretion. Planetisimals continue to grow by colliding and sticking to others until it gets large enough to turn into a protoplanet.The stage where iron falls to the core and alter is generated while lighter materials stay on the outside to create the earths crust. What I did not ilk around the video is how they do not fate how long it takes for it to turn into a protoplanet from a planetisimal. The woman talks close to millions of years to get to the diameter of the particle to centimeters until they start to collide, but lacks the instruction of how long the collisions take to get bigger. They could improve the video by adding these elaborate into it.What I liked some the video is how it goes in depth just about protoplanets and the gravitational collapse as the textbook had me nighwhat confused. The 3rd video is the extra solar planets. It i s about how to detect planets outside of our solar system that gravitate around other stars. They dont try and set out planets directly, they observe the stars in which they believe planets gravitate around and watch how the star reacts. The expressive style they can measure this is through the Doppler affect. As the planet gravitates around it, it pulls the star in different directions.So when a star comes towards you, its light gets compressed, and when it is travel away, the light waves get stretched. What I liked about the video is the way they illustrated how the Doppler affect worked with visuals as oppose to the dog theory in the textbook. That beingness said, what I didnt like about the video was how they focused but on detecting planets through the Doppler affect, I would improve upon this video by not leaving out the other approach of detecting the diversity in light when a planet moves in front of it.The fourth video is about meteorites. It discuses how meteoroids cause meteors, that is until it reaches the ground and ar renamed to meteorites. It then describes how each meteorite is classified by its make-up. Each different composition inside a meteorite allows geologists to identify their space origins. What I liked about the video is how they discussed the different kinds of meteorites and the significance of different compositions of the meteorites. What I didnt like is how they did not touch upon meteor showers and different meteor showers.To improve this video I wouldve included some facts of the Perseid meteor shower. The 5th video is about asteroids. It discusses how Italian astronomer Piazzi discovered the first asteroid. Now there are over 100,000 asteroids that lay in the asteroid belt near deflower and Jupiter. They also describe the reason the asteroids are in the belt could be due to a planet that never formed. The pull of Jupiters sobriety kept the particles accelerating so fast, they could never accrete.What I liked about t he video is how it spent the most time discussing why the asteroid belt exists as that caught my attention the most in the textbook, where its only mentioned briefly. What I didnt like about the video is it didnt discuss the shapes and size of the asteroids themselves. To improve this video I wouldve added some interesting facts from the textbook such as some are asteroids are 200km in diameter. The 6th video is about comets. It talked about how civilization was influenced from comets and the association of comets to earth through eligious or mythological lie societies and how they were viewed as a bad omen. What I did not like about this video is how it did not describe at all what a comet is, or what it is made up of. They could make this video better by discussing the basics of a comet, not just the historic significance it vie on our societies. That being said, what I did like about this video is the telling of how it played a role in our societies that if something bad happen ed, and a comet was in the sky, it started to be associated with each other.
