from the birth of the Earth to the emergence of the world we know today. With help from host and scientist‚ Richard Smith‚ we meet titanic dinosaurs and giant kangaroos‚ sea monsters and prehistoric crustaceans‚ disappearing mountains and deadly asteroids. The visuals (both real and computer-generated) are beautiful‚ and the stories are clearly and engagingly told. The program builds an appreciation for the landscape by allowing you to fully explore the rich history of Australia. In the first

Extinction and Evolution Ecology helps us understand the importance of mass extinction in evolution‚ and it also helps us understand some of the causes of extinction. Ecological niche is one of the most important concepts to understand. An animal or plant lives in a certain place is active at a particular times‚ and eats certain things; all these factors describe its ecological niche. Our environment is parted into millions of ecological niches‚ each that represents a probable home for life

Madison woke up this morning and felt a little dizzy. She figured she just needed something to eat and she would be fine. Robert‚ her dad‚ was just coming up the stairs to wake her up. He is a news reporter so he has to leave early. Normally he wakes her up about the time he is leaving. Every day after school‚ Madison goes home and watch my dad on tv. Today’s show was weird. You could tell they were concerned about something. They were talking about the differences in the rotation of the earth. Madison

for gravity assists to boost momentum enough to send them beyond the asteroid belt. Rendezvousing with asteroids and comets can be even more challenging; they lack sufficient mass to brake fast-moving spacecraft into orbit‚ so the ships must perform years of orbit adjustment to match position and velocity with the tiniest worlds. Power is also a problem. Located very far from the Sun‚ comets‚ outer planets‚ and most asteroids receive very little solar energy. Solar arrays must be very large to

It is believed Earth may be in the midst of another mass extinction‚ also known as ’The Sixth Mass Extinction ’. This mass extinction is the first for 65 million years since the Cretaceous-Tertiary period. "It ’s the next annihilation of vast numbers of species. It is happening now‚ and we‚ the human race‚ are its cause ’ (Leakey‚ 1995). Every year‚ between 17‚000 and 100‚000 species vanish from our planet‚ which will result in fifty per cent of the Earth ’s species vanishing inside the next 100

Question One: Is blue moon (body 3) circling the yellow sun (body 1) or the purple planet (body 2)? Explain your answer. Using the trojan asteroids setting it looks like all 3 bodys are orbiting the yellow sun 4. Increase the mass of the sun (body 1) to 400 and allow the simulation to run for one complete orbit of the purple planet (body 2). 5. Decrease the mass of the sun (body 1) to 175

Super volcanoes We are now in year 2016‚ and I believe that almost all people in the United State remember the disaster film called “2012”. The catastrophe included great eruptions of super volcanoes in America‚ such as Yellowstone. There are a lot of scientists doing researches of super volcanoes‚ and trying to predict when will the super volcanoes erupt again. Today I would like to introduce some knowledge of super volcanoes‚ and the reason why people do not need to worry about hazards of eruptions
