Understanding the Compostion of Planet Earth

There are two main ways scientists learn about Earth’s Interior. The first way is, of rock samples. Scientists use drills to get as close as they can to get to the center of the earth, they also looked at rocks that spat out of volcanos during a volcanic explosion. The second way is, because of seismic waves. They study how seismic waves travel through Earth, seismic waves are vibrations that travel through Earth carrying energy, released during an earthquake. Those were the two main ways how scientists learned about Earth’s interior.

For centuries, humans thought that the center of the Earth was hollow, but here’s how we know it’s not. Most data that we have found about the interior has come from the study of seismic waves. From that, we’ve learned that the internal area of the Earth is made out of solids and liquids. However, there is other materials that are available that show us what the Earth interior is composed of. Three additional ways that scientists study the interior of the Earth are the diamond that came from the mantle, studying of neighboring planets, and meteorites.

The telescope is very massive it is actually the size of a school bus and weighs about as much as much as 2 grown elephants. The telescope orbits the Earth about 340 miles above.The telescope can travel at about 5 miles per second, this is very cool because that would mean the telescope travels at 18,000 miles per hour. The telescope was supposed to be launched into outer space in the year 1985, but the space shuttle challenger exploded and the launch was postponed while Nasa tried to figure out how to safely resume the launch. In the year 1990 the telescope was launched. The telescope uses digital cameras to get pictures and information and send them through radio waves. The parts of this incredible telescope include, a wide field camera which is a camera that “has higher resolution or ability to distinguish details and a larger field of view or area.”(http://hubblesite.org/) The cosmic origins spectrograph “break light into colors and measure the intensity of each color, revealing information about the object emitting the light.”(http://hubblesite.org/) The advanced camera for surveys is a camera that “ sees in wavelengths from the far ultraviolet to visible light, making it capable of studying some of the earliest activity in the universe.”(http://hubblesite.org/) There are many other parts to the Hubble telescope and all of the parts that were needed for this telescope were put together and created this amazing

The solid part of the Earth consist of solid rocks and soil. The Earths surface is the geosphere. The hydrosphere makes up all of the water on Earth's surface. The Earth is divided into three layers the crust, mantle, and the core. The crust is very brittle and this is why it was easy for Mount St. Helen to blow it to pieces. Tectonic plates are what glides underneath the underlying asthenosphere. This is what causes mountains to shift or grow. This can affect when volcanoes erupt. Volcanos are located near tectonic plate boundaries, where plates either collide or separate.

Talk about the history and great discoveries of the Hubble Telescope. Why was the Hubble constructed? What were some of the problems encountered and how has it moved the discoveries of the universe forward.

The only thing standing in Edwin’s way of getting a clean picture of the stars was this thing known as the Earth’s atmosphere, which because of the fluidic gas and dust that make up the atmosphere it often “blurs visible light, causing stars to twinkle and making it difficult to see faint stars.”(Dunbar) As this makes his job virtually impossible, a German scientist comes up with the idea of a telescope in space to not only see farther but also to see clearer, this was a crucial turning point in Hubble’s findings and will eventually lead to the one of the greatest and most recognized theories around the world.

On April 24th of 1990, The Hubble Space Telescope was launched. This was an important event for NASA, because they finally had something to looked further into the space. The Hubble Space Telescope was known as (HST), and it was sent to orbit around our earthly planet. Did you know it took only 97 minutes to orbit around our planet? Hubble Space Telescope helped change the NASA’s thought on the universe because,

In the article, Ancient History and Ancient Ancestors,the Earth’s continents are not fixed in place and they slide over the molten mantle. The ocean poured in and

The thing that created my planet was the Big Bang. The Big Bang caused tiny, and big particles, rocks, and atoms to form together to create my planet. Those particles, rocks, and atoms created four layers in the planet. The crust, mantle, outer core, and inner core. The crust makes up 1% of the earth and is the outermost layer. Just below the crust is the mantle. It is the largest layer, and it is semi-solid. Below the mantle is the outer core. Made of 5,000 degrees celsius liquid iron, it creates a magnetic field that protects the earth from deadly particles, and from harmful UV rays. Scientists are even predicting that the poles will flip because of it. The most inner and dense layer is the inner core. It is a solid ball of iron that should be liquid, but due to too much pressure it is solid. How do we know what the layers are made? Seismic waves. There are two types; P-waves

It’s been around for twenty years, it’s made over 930,000 observations, it has taken around 570,000 images of celestial objects, it has helped us figure out how old our universe actually is, plus much more. Do you know what NASA uses to find those things out? No? Yes? Well let me tell you, it’s the Hubble telescope. Now you may be asking what’s the Hubble Telescope? What is a Hubble telescope? Or you might just be thinking “oh I already knew what that was”. If you know what I’m talking about this shouldn’t be too confusing for you, but if you don’t know, well now you can finally learn about what helps us discover many things in our solar system. The Hubble telescope was not made by the actual person, in fact, it was named after him because

We had to a drill big and strong enough to get to the center of Earth. Also, suit that would keep me cool. Then I was off to the center of earth. I saw basalt and granite in the crust. It was very hot in the crust. When i hit the mantle, it cooled off a little bit. It felt like it took about a year but it only took about a month or two to get out of the lithosphere. Then i hit the asthenosphere and it took about two to three months to get out of the asthenosphere.Then i got to the outer core which is liquid. So i cut of my engine so it wouldn’t waste the gas and started to sink. It was getting a little colder the lower i got. It only took about five hours playing the xbox i put in the drill and then when i reached the inner core, i turned it

The Earth has four layers. The Crust is what we can see, there are two types of crust, Oceanic and Continental. The Mantle is the second layer where it is solid. The Outer layer is liquid, which can be proven due to the heat of the Outer layer. Lastly the Inner layer where there is more iron and more density.

The Hubble Space Telescope was launched in 1990 in order to execute planetary exploration and discovery. It is known to be NASA’s most successful and lifelong science space mission. By making approximately more than millionth observation of deep space, the Hubble telescope helped to identify unknown objects in space, the existence of dark energy, the age of the universe and the physical process that take place in astronomical objects.

The earth is divided into three main layers: the core, the mantle and the crust. The core is further divided into the solid inner core and the liquid outer core. This layer is

Earth is in fact an intricate planet that has multiple layers of differing compositions. To be exact the earth has four main layers. The uppermost layer is the one humans come in most contact with, the crust. The crust consists of “thin silicate rock material”(Structure of the). Although the crust is not entirely the same. Actually there are two distinct types of crust, oceanic and continental. “The continental crust is made up of mostly rocks similar to granite while the oceanic crust is much denser and made up of a material similar to basalt”(Structure of the, Rose). The second layer is called the mantle. “The mantle is much denser than the crust and contains similar to the crust mostly solid silicate crust”(Structure of the). “As we travel further down the earth we wind up in the outer core. The outer core is a core of molten nickel and iron. Finally there’s the inner core. The inner is a solid metal core made up of nickel and iron”(Structure of the). All these layers functioning together cast out a magnetic
