age of earth CORRECT ANSWER our understanding of radioactivity helps us accurately determine numerical dates for rocks that represent important events in earth's past. Earth is about 4.6 billion years old. Asthenosphere CORRECT ANSWER "weak sphere" 400km deep, small amount of melting, mechanically detached from lithosphere, which can move independently craton CORRECT ANSWER interior of a continent, oldest part density CORRECT ANSWER defined as mass per unit of volume, determines how ...

Accretion Wedge - Answer The accumulation of material at the point of subduction. Aseismic Buildings - Answer Buildings designed to withstand or minimise destruction during an earthquake. Asthenosphere - Answer The upper mantle layer of the Earth. It is semi-molten and approximately 2000km wide. Ash - Answer Fine particles and dust ejected during an eruption, which can remain airborne as clouds or accumulate on the ground. Continental Crust - Answer Crust that forms th...

core : Center of the earth; composed of iron and some nickel; solid inner core & liquid outer core mantle : the layer of of earth outside the core; mostly solid and makes up about 70% of Earth's volume crust : the rocky outer shell of the planet lithosphere : thin, upper part of the mantle and the outermost crust; the rock consists of cooler, brittle rock asthenosphere : below the lithosphere; contains malleable rock that can move over time igneous rock : molten magma that has ...
