Answer:
1. lava
2. crystals
3. rivers, deposition, weathering
4. heat and pressure
5. Sedimentary rocks
Step-by-step explanation:
1. igneous rocks from from lava, hence, the name
2. magma forms crystals, so the process at which they melt alters the sizes
3. sedimentary rocks occur due to extreme pressure over time, such as weathering, or rain
4. heat and pressure for a long period of time can melt and from new rocks
5. Sedimentary rocks from from pieces of other rocks
