What is RADIATION
Explain what causes a banana to appear yellow.
What is THE BANANA REFLECTS YELLOW AND ABSORBS ALL THE OTHER COLORS OF LIGHT
Explain how metamorphic rock can become sedimentary rock.
Weathering and erosion wear away the metamorphic rock, forming particles (sediment) then the sediment will eventually compact and cement into sedimentary rock.
