  2. Mechanically

  3. Physically

  4. All of these

Show answer
Correct Option: A
Explanation:

Chemical sedimentary rocks are formed by the precipitation of minerals from water. Precipitation is when dissolved materials come out of water. They are typically made up of the minerals halite (calcium chloride, or rock salt) and gypsum (calcium sulfate).

  4. Liquid

Show answer
Correct Option: B
Explanation:

B. Minerals

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, resistance to tarnish, and its many special properties - some of which are unique to gold. Its rarity, usefulness, and desirability make it command a high price. 

The term mineral is sometimes used in reference to natural earth (non-living) resources, and thus, in a non-scientific sense, petroleum resources are mineral resources and deposits of petroleum are often called mineral deposits. Coal, sands, gravel, and such would also be considered a mineral resource in this particular usage, even though coal is a rock, not a mineral, and the others are mixes of multiple minerals and/or rocks and not, strictly speaking, minerals.

  1. Igneous rock

  2. Sedimentary rock

  3. Metamorphic rock

  4. Sand stone

Show answer
Correct Option: A
Explanation:

Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Igneous rocks occur in a wide range of geological settings: shields, platforms, extended crust, basins, and oceanic crust.
