Earth Science Practice Test 100% Solved 2024

Earth Science Practice Test 100% Solved 2024 What are the 4 layers of earth - Correct Answer ️️ -Crust, mantle, outer core, inner core Where is the lithosphere located? - Correct Answer ️️ -Upper mantle plus crust Where is the asthenosphere located? - Correct Answer ️️ -Middle mantle What are the 3 types of boundaries? - Correct Answer ️️ -Divergent, convergent, and tranform Warm air rises or sinks? - Correct Answer ️️ -Rises How can heat be transferred? - Correct Answer ️️ -from hot objects to cold objects in three ways; convection, conduction, and radiation Continental crust is made out of what? - Correct Answer ️️ -Rocks such as granite Cool air rises or sinks? - Correct Answer ️️ -Sinks What is Pangaea? - Correct Answer ️️ -A single landmass that broke apart 250 million years ago Does density have an affect on whether convection currents form in liquids or gases? - Correct Answer ️️ -Yes Why was Alfred were era hypothesis about plate tectonics rejected by other scientists? - Correct Answer ️️ -He could not explain the forces that pull and push the continents apart What are mid ocean ridges? - Correct Answer ️️ -Places where oceanic crust is pulled down at the trench Explain tranform boundary - Correct Answer ️️ -Motion- Plates slide past each other Effect on crust- broken and cracked GF - earthquakes and faults Explain convergent boundary - Correct Answer ️️ -Motion- plates come together Effect on crust- subduction or mountain building GF- volcanoes p, mountains Explain divergent boundary - Correct Answer ️️ -Motion- plates moves away from each other Effect of crust- Spreading ridges GF- mid ocean ridge, ocean floor Explain how density and temperature affects the convections currents of a liquid - Correct Answer ️️ -Density and temperature effect convention currents because the temperature heats up the part of the liquid making the liquid less dense. Since the liquid is less dense it moves up and away from the warm temperature only to be cooled. Meanwhile the other cooler liquid takes the previous liquids place. The cold part of the liquid becoming more damage causing it to seek back down. The cycle repeats but using the other cooled liquid that took the other liquids place, causing a circular motion. Explain hose convection currents help shape earths landscape - Correct Answer ️️ - Convection currents help shape Earths landscape because convection currents affect plate tectonics by moving the crust in the direction of the current. Those plate tectonics then make convergent, transform, or divergent boundaries which creates landscapes like mid-ocean ridges, ocean floor, volcanoes, faults, and mountains. Explain hose geographical features forms when tectonic plates moves + 3 examples - Correct Answer ️️ -The geographical features form when plate tectonics move because they make convergent, divergent, and tranform boundaries. 1.) two continental crust plates collide making mountains 2.) two plates move apart creating mid-ocean ridges and ocean floor 3.) two plates slide past each other in opposite directions creating faults. What's does the theory of plate tectonics state? - Correct Answer ️️ -Pieces of earths lithosphere are in slow constant motion, driven by the convection currents in the mantle What does the theory of plate tectonics explain? - Correct Answer ️️ -The formations, movement and subduction of the plates makes changes in the earths crust as the plates move: volcanoes, mountain ranges , and deep ocean trenches What happens when you go deeper and toward the center of the earth? - Correct Answer ️️ -Temperature and pressure increases What does the oceanic crust consist most of - Correct Answer ️️ -Basalt ( dark rock with fine texture) What is the continental crust made mainly out of? - Correct Answer ️️ -Granite ( course texture with light color What happens to size mic waves when they enter a new layer of the earths crust? - Correct Answer ️️ -Reflect, and this proves that earth has layers
