Rock types, plate tectonics, and the processes that shape the Earth's surface over time — nearly everything in this subtopic connects back to the rock cycle and the plates constantly shifting beneath it. Every question comes with a written explanation of the process involved.
Weathering breaks rock apart where it sits; erosion is the separate process of moving that broken material somewhere else — a question describing movement is testing erosion, not weathering.
Convergent boundaries (plates colliding) typically build mountains or create subduction zones; divergent boundaries (plates separating) create new crust and rift valleys — the two produce essentially opposite landforms.
Any of the three rock types — igneous, sedimentary, or even another metamorphic rock — can be transformed into metamorphic rock through enough heat and pressure; there's no rule that it has to start as igneous.

A rock forms when magma cools and solidifies. What type of rock is this?
Two tectonic plates are moving directly toward each other, with one plate being forced beneath the other. What type of plate boundary is this, and what is this specific process called?
A geologist finds a sample of quartzite, which forms when intense heat and pressure transform sandstone (a sedimentary rock). What type of rock is quartzite, and does this example follow a rule that sedimentary rock must first become igneous before it can become metamorphic?
Geology questions reward tracking process, not just vocabulary — the rock cycle and plate boundaries are both defined by what's happening, not by a fixed starting point.
For every rock or plate-boundary question, state the specific process — subduction, weathering, cooling — before picking a final answer. Untimed practice is where that habit sticks.
Move to timed sessions once the three rock types and three boundary types are instant recall.
Pair geology with meteorology in a mock — both build on the same Earth-systems foundation, just above versus below the surface.
