Who is right? Which best describes convection currents? Magma rises in the mantle because heat makes it less dense and then sinks when it cools off because it is more dense Magma rises in the mantle because heat makes it more dense and then sinks when it cools off because it is less dense vs.
When I say transform you say Slide When I say Divergent you say Apart When I say convergent you say collide

Answer • Pulling apart • rift valleys Ocean ridges
Question #7 What is a transform boundary • The motion • what happens there
Answer • Sliding • earthquakes
Question #8 What is the 3 main types of evidence that help prove continental drift?
Answer • Fossils (glossopteris) • Climate (tropical plant fossils found in sedimentary rock in polar climates • Landforms (mountain range in Argentina matches that in South Africa, continents seem to fit together)
Question #9 If new crust is being formed, why is the earth not getting bigger?
