1. What geomorphic process involves transport of rock meaterial over earth's surface by water, wind , or ice?

a. Tectonic activity

b. Erosion

c. Faulting

d. Weathering

2. Finely divided particles of mineral and/or organic matter transported by water, wind, or gravity are called:

a. Glacial deposits

b. Drift

c. Tidal remnants

d. Sediments

3. Dark heavy minerals, rich in silicates of magnesium and iron, which dominate the composition of the oceanic crust are called:

a. Felsic minerals

b. Micas

c. Clastic

d. Mafic minerals

4. Rocks that are transformed deep in the crust by heat or pressure, or both, are classified as:

a. Sefimentary rocks

b. Metamorphic rocks

c. Plutonic rocks

d. Igneous rocks

5. Course-gained igneous rocks are:

a. Formed on the surface by solidification of lava

b. Intrusive igneous rocks

c. Formed under the surface by solidification of magma

d. Both b, and c

6. Sediments are deposited in horizontal layers on earth's surface. Sedimentary rocks commonly show distinct layering in their form, an observable characteristic called:

a. Lithification

b. Compaction

c. Horizonation

d. Stratification

7. Which of the following is not a sedimentary rock?

a. Sandstone

b. Limestone

c. Granite

d. Shale

8. In the rock cycle, the following transormation between major rock types can occur:

a. Igneous rock is re-crystallized into metamorphic rock

b. Metamorphic rocks are subducted, melted, and later become igneous rocks.

c. Sedimentary rocks are made into metamorphic rocks by heat and pressure

d. All of above

Explanation / Answer

1) a) erosion, as erosion is the process of transfer of rock materials from one place to other under the action of wind and water.

2) d) sediments, these are small particles which travel under the action of wind and water and settles due to gravity

3) b). Micas, these are rich in silicates of magnesium and iron and are useful ores too.

4) d). Igneous rocks,

5) d) Both b, and c, these are formed by both th actions

6) c) Horizonation,

7) d) Shale, the are made under different actions of sea

8) a) Igneous rock is re-crystallized into metamorphic rock, because it is the first thing that magma turns into
