Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.

What is the difference between magma and lava?
(Student response here)
Both are hot molten liquid rock. Magma forms under the Earth’s surface in the crust or mantle. Lava is molten rock that erupts onto the Earth’s surface. So they are essentially the same stuff, and the name changes based on its spatial relationship to the earths surface.
Magma is a molten rock found beneath earth's surface; lava is once magma erupts from a volcano.
Magma is the term used for molten rock inside earth while lava returns to that same molten rock once it has erupted and is exposed to the surface.
Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows out of a volcano during an eruption.
What type of rocks result from the crystallization of magma or lava?
