Match the descriptions to the correct rock types or processes.

Here are the answers for Activity 2.1:

2.1.1 Rocks formed when magma solidifies: F Igneous
2.1.2 This rock type occurs as layers or strata: L Sedimentary
2.1.3 Rocks formed when heat or pressure is added: D Metamorphic
2.1.4 Recognizable remains of plants and animals preserved in rocks: B Fossils
2.1.5 Processes that cause rocks to form, break down, change, and reform over time: E Gneiss (This refers to the rock cycle, but Gneiss is a metamorphic rock formed through these processes, making it the closest match from the options provided for a specific example of a rock type that undergoes such changes.)
2.1.6 Sandstone change under heat and pressure to...: A Quartzite
2.1.7 Limestone turns to... under heat and pressure: C Marble
