What is the origin of the Earth? - Answer-Formed out of a solar nebula What are the origins of Life? - Answer-Archaea - the oldest origin of life on Earth What is kinetic energy? - Answer-The energy of motion What is heat energy? - Answer-Energy created by particles of matter rubbing together What is density? - Answer-A measurement of the amount of matter in a given volume of something. (mass per unit volume) What is convection? - Answer-Transfer of heat through currents caused by differen...

Second Continental Congress - ANSWER-A convention of delegates from the Thirteen Colonies that started meeting in the spring of 1775 in Philadelphia, Pennsylvania. Managed the Colonial war effort and moved incrementally towards independence, adopting the United States Declaration of Independence on July 4, 1776.

Anthro 2B Final (Egan) verified answers and questions 2023. macro-evolution - correct tion above the species level micro-evolution - correct tion below the species level speciation - correct s when one species splits into two, which involves a reproductive isolating mechanism example of reproductive isolation but NOT speciation - correct rd frogs in Florida vs. Maine, can still reproduce but just can't because they are isolated; gene flow can happen extrinsic is...

Describe what happens when two tectonic plates collide along a subduction zone. correct answers One plates moves under another and sinks into Earth's mantle. A trench may be formed Explain how subduction leads to volcanic activity correct answers One plate is pushed down and melted as molten material/ magma rises to the surface near the zone What areas exhibit island arcs correct answers Coast of Asia (Philippines, Ryukyu, Japan, Kuril, and Aleutian) What areas exhibit a growing nonvol...

TMS Tectonic Plate Boundaries and Landforms Complete Test With Complete Solutions. Trench - CORRECT ANSWER A deep drop off formed at a subduction zone Volcano - CORRECT ANSWER A landform built of igneous extrusions over time where a plate is subducted and partially melts Subduction - CORRECT ANSWER Process where one plate is pushed under another at a convergent boundary Folded mountains - CORRECT ANSWER A mountain chain formed where two continental plates converge and squish the ro...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...

Texas Teacher Exam - Science minerals - ANS ️️ A solid inorganic substance of natural occurrence. tectonic plates - ANS ️️ Sections of the Earth's crust that move due to convection currents. tectonic plates - ANS ️️ pieces of the lithosphere that move around on top of the asthenosphere oceanic crust - ANS ️️ earths crust located under the ocean. The thinnest type of crust. Mostly basalt continental crust - ANS ️️ thicker, less dense crust making the continents magne...

Theory of Plate Tectonics - ANSWER A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithosphere? - ANSWER African, Antarctic, Australian, Eurasian, North American, South American, Pacific, Cocos, N...

origin of earth - Answer-• Supernova: death of a star (great explosion) • Supernova happened 4.6 bya, dust and gas flattens to a disk and spins faster due to gravity and solar nebula formed. • Solar Nebula: describes formation of Earth 4.5 bya • Nebula: gas cloud origin of oceans - Answer-• volcanic explosion, H2O condensed and rained down for thousands of years to create oceans • icy comets hitting earth (responsible for 1/2 of earths ocean water) origin of life - Answer-•...

big bang : -still energy left from explosion -discovered in 1960s -assumes earth came from material -Kant created most pop model of formation (planet accretion) nebula : beginning form of planets many bump into others and combine earths composition : -more dense material in center -heterogeneous (bc heat and dense elements melt and flow) 2 -accretion -compression -radioactive decay 3 layers of earth : -based on composition -core, mantle, crust -metallic core sank to center lit...
