Kirat Hundle 1. What is the difference between an element and a compound? An element is an isotope made of the number of neutrons it has. A compound is a substance made of two or more different elements (a mixture). 2. What is the periodic table? A periodic table is where the chemical elements are organized based on their atomic number (number of protons in the nucleus)‚ electron arrangement‚ and chemical properties. 3. Give two examples of each of the four major mineral groups (silicates‚ carbonates

World At Risk Global Hazards There are different types of hazard 1) A hazard is something that’s a potential threat to human life or property. 2) Natural hazards are cause by natural processes. 3) Natural hazards can be divided into two types: * Hydro-meteoroidal hazards (caused by climatic processes)- these include droughts‚ floods‚ tropical cyclones and storms. * Geophysical hazards (caused by land processes) – these include earthquakes‚ volcanic eruptions and landslides.

southern Montana and Eastern Idaho. It is one of America’s largest‚ oldest‚ and most well known national parks. DISCUSSION I. Thousands of years ago‚ numerous volcanic eruptions shaped the landscape of Yellowstone. A large mass of molten rock (magma) that lies beneath the park fuels the geothermal activities seen there today. A. 1803—Obtained as part of the Louisiana Purchase B. 1872—American government establishes Yellowstone as a national park C. Named for the yellow rocks that lie

Mercury the closest planet to the Sun: Mercury‚ and the other inner planets‚ condense from the heavier elementes. Condensing closest of all to the sun‚ Mercury is rock solid. Outwardly‚ Mercury is like our Moon: rocky‚ cratered‚ barren. But inside‚ like Earth‚ is an iron-rich core. That core is as big as the Moon and‚ at 70% iron‚ Mercury is the densest planet of all. Also Mercury’s day is twice as long as its year. The day lasts 176 Earth days‚ the year just 88. But it gets stranger... If you

also made up of iron and nickel. It is still extremely hot‚ with temperatures similar to the inner core. 3. The mantle is the widest section of the Earth. It has a thickness of approximately 2‚900 km. The mantle is made up of semi-molten rock called magma. In the upper parts of the mantle the rock is hard‚ but lower down the rock is soft and beginning to melt. 4. The crust is the outer layer of the earth. It is a thin layer between 0-60 km thick. The crust is the solid rock layer upon which we live

they react and form carbon dioxide. They become “uncomfortable” like it is allergic to each other and it automatically breaks apart into water and carbon dioxide‚ which makes the liquid inside comes out. Answer to question 3: Volcanoes form when magma from within the Earth’s upper mantle works its way to the surface. Over time‚ the volcano continues to erupt and it gets bigger and bigger. We also collected the data and got these results: Our hypothesis was half correct. The hotter the vinegar

Who is the scientist who did much of the early work on continental drift? In the early 20th century‚ German scientist Alfred Wegener published a book explaining his theory that the continental landmasses‚ far from being immovable‚ were drifting across the Earth. What evidence did this scientist have to support his idea of continental drift? Wegener noticed that the continents seemed to fit together‚ not at the continuously changing shoreline‚ but at the edge to their continental shelves
