With reference to Intrusive Igneous Rocks which of the following is incorrect?

1. Batholiths — deep-seated large deposits of igneous rocks like graphite.
2. Hypobyssal Rocks — small rock deposits.
3. Neck — plug at the top of a volcano.
4. Dykes — large deposits of cooled magma on the earth's surface.

The process that turns loose sediments into rocks:

1. Compaction
2. Lithification
3. Cementation
4. None of the above

Transported sediments get deposited in layers leading to increased pressure and temperature on the lower layers. Select the correct sequence of processes involved in the lithification of these sediments.

1. Compaction — Evaporation — Cementation.
2. Evaporation — Compaction — Cementation.
3. Evaporation — Cementation — Compaction.
4. Evaporation — Dehydration — Cementation.

Sam was working under a geologist. He lost his balance and dropped the bags containing igneous rocks and sedimentary rocks and the rocks got mixed. How would he separate them?

1. Igneous rocks are hard.
2. Igneous rocks are crystalline.
3. Sedimentary rocks have strata showing layers.
4. Sedimentary rocks are soft.
