This Is What It Would Look Like If A Huge Asteroid Hit The Earth. Earth has a long list of hits—and not of the musical variety, but of the rocky, celestial sort.

This Is What It Would Look Like If A Huge Asteroid Hit The Earth

In fact, asteroids have slammed into our planet and caused cataclysmic damage many times in its violent past. On less dramatic occassions, Earth is frequently hit with small asteroids that enter and disintegrate in its atmosphere. According to NASA’s Jet Propulsion Laboratory, Earth was hit by 556 small asteroids between 1994 and 2013. Most don’t make it through the atmosphere, but some—like the Chelyabinsk meteorite—crash-land with considerable force. What would happen if a larger asteroid collided with Earth? If you want to test out your own apocalyptic scenario, there is an online site by Purdue University called Impact Earth that allows users to input their own parameters.

The Best Sites To Learn About Climate Change

It introduces students to the problem, and it also teaches them about the “Five W’s” – who, what, where, when and why. A writing prompt is included. I thought it would be helpful to put together a list of related online resources that are accessible to English Language Learners. I also have a number of links on The Best Sites To Introduce Environmental Issues Into The Classroom, and won’t be duplicating them here. So you might want to check-out that list, too. Countdown To Copenhagen is a Wall Street Journal interactive timeline displaying major events related to climate change over the past forty years. Advancing Emissions is another interactive from the Wall Street Journal charting changes in greenhouse gas emissions over the past forty years. Breathing Earth is an intriguing visual representation of the effect each country has on climate change.

Copenhagen Challenge is an online game on climate change. U.S. BELLAGAIA 5min sample. SpaceFlight Insider – Commentary: 5 Ways Outer Space Taught Us About Earth in 2013. Another year of the Internet has come to a close, which can only mean one thing: time for more lists!

SpaceFlight Insider – Commentary: 5 Ways Outer Space Taught Us About Earth in 2013

The science magazines will undoubtedly create exciting top 10′s of the most awesome things to happen in space in 2013. But some of the stories that most need telling are not the big-ticket tales of human spaceflight and new exoplanet discoveries. For most people, it’s the less flashy things that can mean the most in the lives of people right down here on Earth.

And these benefits are not limited to spinoffs like microelectronics and high-tech medical technologies that people from rich countries enjoy; from human rights to food security, space assets provide incredibly meaningful humanitarian contributions to the planet. Here are five of the many ways in which space touched us down here on Earth in 2013: Photo Credit: CAR 1) Space assets helped human rights workers uncover war crimes in the Central African Republic Space assets were used to help refugees recovering from Typhoon Haiyan.

The total amount of energy in the system remains constant. This is very hard to imagine, but we can use simple simulations and experiments to demonstrate the property. One way to do this is by dropping a soccer ball with a tennis ball balanced on top. You can calculate the energy difference and how it is transferred to the tennis ball. We can do the same thing with force carts in physics. Simulation: When gases are mixed in a container, they each act as if they are the only gas present. Every gas at the same temperature has the same average energy. It’s a Gas: Math and Science of the Blimp - Gas Laws If gases are always moving, can they ever come to a complete stop? This video is of a model demonstrating how gas molecules behave: Gases behave differently from the other two commonly studied states of matter, solids and liquids, so we have different methods for treating and understanding how gases behave under certain conditions.
