EAPS 106 Exam 1, Review Questions and answers, rated A+ How the Earth acquired its internal heat From internal collisions Why the interior of the Earth is layered (crust, mantle, core) and the relative thickness of the layers When the Earth was being created, heavier metals that are more dense (iron and nickel) sank to create the core. Lighter materials such as silicon and oxygen floated to become the crust and mantel. Crust is thin, mantle and core are miles thick (Earth is like a pea...

Marine Science Exam Test Questions Correct Answers New Update Scientific data suggest that the age of Earth is about ________ years. - Answers -4.6 billion Scientific data suggest that the age Earth's earliest fossilized life form is ________ years - Answers -3.5 to 3.9 billion From earliest to most recent, which of these is a correct order of formation? - Answers -nebula, protostar, star, supernova planets formed in the early solar system as particles orbiting the sun were attracte...

What is Geology? Geology is the study of the earth, including the earth's composition, structure and the processes that have shaped it What geologic factors influence people? Mountains and valleys, volcanoes, faults and earthquakes, rivers, climate, natural resources What are the three natural resources? Minerals, oil, water How are populations influenced by geology? Low populations tend to live in extreme terrain where places of high population are usually on flat land...

and convergent boundaries - ANS plates that come together, possibly forming subduction zones therefore forming ocean trenches, volcanic activity, trenches, and earthquakes (->tsunamis) divergent boundaries - ANS plates going apart, causing seafloor spreading and forming volcanoes, mid-ocean ridges, abyssal plains, and hydrothermal vents transform boundaries - ANS plates moving in opposite directions, frequently causing earthquake activity ocean trenches - ANS ...

Where are berms found? - correct answer Berms mark the position of mean high-tide marks Conditions for marram grass? - correct answer Resistant to salinity, wind, lack of moisture Why are mangroves under threat? - correct answer Cleared because of disease, Aquaculture, Deforestation Why are sand dunes under threat? - correct answer Caravan parks, Golf courses Ba...

CSUF GEOL 310T-09 Henderson Plate Tectonics 100% Solved seafloor spreading The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface. Alfred Wegener A German scientist who proposed the theroy of continental drift Gondwanaland The continents of Africa, South America, India, Australia, and Antarctica when all the continents were a single landmass. Mantle The layer of hot, solid material between Earth's crust and core. Made of olivine a...

EARTH 106 Exam 1 Core - correct answer made of metal, mainly iron (Fe) & nickel (Ni) has inner and outer parts Inner core - correct answer solid Outer core - correct answer more liquid metal Mantle - correct answer made of rocks, denser and darker, made of oxygen & silicon, richer in iron (Fe) & magnesium (Mg) than those on the crust Crust - correct answer thin, light, outermost layer, made of rocks (less dense and lighter than those in the mantle) has oceanic and continental ...

geology - correct answer the study of ancient seas, rivers, and other environments How are the two sides of North America different from each other? - correct answer The western part appears more complex because it has many mountains and valleys The mountains in the eastern US are mor subdued and the east coast is surrounded by a broad shelf that continues out past the Atlantic The center has no l...

GLG 101 Final Exam | questions and answers | 2023/24 Rock Cycle - Magma cools and solidifies creating igneous rocks. Igneous rocks are exposed at the surface and eroded away creating sedimentary rocks. Sedimentary rock deform under heat and pressure to form Metamorphic rocks. How we determine the relative ages of rocks - We place rocks in their proper sequence of formation. Which rock formed first,second, third, and so on. Rock Types - Igneous Sedimentary Metamorphic Igneous Rock...

How is a pressure defined? What are the SI units for pressure (or stress)? correct answer: pressure = force/area = mass/volume units are Pascals 1 Pa = 1 kg m s⁻² How would you compute the pressure at the base of a column of material of any thickness or density? correct answer: P = ρgH where H is height of column, ρ is density of column material Definition of the crust and mantle correct answer: crust & mantle defined by their chemical composition crust→ outermost...
