Science Questions

1. What are differences between metamorphic, sedimentary, and igneous rocks?
Ans. Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products ofweathering by cementation or precipitation on the Earth's surface. Metamorphic rocks, formed by temperature and pressure changes inside the Earth.

2. What rock did you find the most interesting? Why?
Ans. Granite Because it is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals.

3. What are grains in the rock? Can you show me?
Ans. a sedimentary rock might have individual grains of sand held together by a natural cement. Grains of an igneous rock are individual crystals that have grown as a magma cooled.














4. What are the crystals in the rocks? Can you show me?
Ans. If the magma cools slowly, large crystals form in the rock. This can happen if the magma cools deep underground.

Scoopula - a utensil used to transfer solids (usually in powdered form).

7. Watch glass - A watch glass is a circular concave piece of glassused in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker.

8. O wire - Used for flame tests and especially bead tests of minerals and other unidentified inorganic compounds.

9. Evaporating dish - used to boil off liquids, leaving dissolved solids behind.
