LUOA Earth Science Module 8 (2023/2024) Already Passed Glossopteris was a temperate climate leaf fossil. He found it in Antarctica. How could this be? Because that fossil was supposed to have been in a temperate climate near the equator but instead was in Antartica, meaning that the continents have moved since the beginning of time. Alfred Wegener discovered rocks in the Appalachian Mountains matched rocks in _______________________. Europe and Greenland Originally, Wegener's hypothesis that...

tidal hypothesis : Theory that the solar system started with a near collision of sun and large star. Few astronomers believe this theory. condensation hypothesis : solar system began with rotating clouds of dust and gas. Condensation happened in center to form sun, and smaller parts of clouds formed. More astronomers believe in this idea. Core : Outer core- liquid; inner core- solid. Very dense in center. Believed that core is 80% iron. Helps heat oceans. Mantle : Surrounds core. ...

Mean rate of reaction (with reactant) - Answer Rate of reaction: Quantity of reactant used ---------------------------- Time taken Mean rate of reaction (with product) - Answer Rate of reaction: Quantity of product formed ---------------------------- Time taken Measurements for quantity of product or reactant - Answer Either as mass in g or as volume in cm³ Measurements for the rate of reaction - Answer Either as g/s, cm³/s, or mol/s Factors which affect rate of c...
