Which process begins the formation of sedimentary rock?

the movement of sediment
the cementation of rock sediment
the breakdown of rock into sediment
the buildup of sediment in one location

Answers

Answer:

Weathering breaks down pre-existing rock into particles, while erosion moves the particles to a site of deposition. These processes begin the formation of sedimentary rock.

Explanation:

Sediment is the term for the component that aids in the formation of sedimentary rock. All of the processes that lead to the sedimentation of organic and mineral particles are together referred to as sedimentation. The cementation of rock sediment forms sedimentary rock. The correct option is B.

What are sedimentary rock?

Sedimentary rocks are created by the material being deposited at the Earth's surface and then being cemented there by bodies of water. Existing rocks or pieces of extinct animals that have accumulated on the surface of the Earth over time generate sedimentary rocks.

Sediment is crushed and cemented as a result of deep sediment burial, creating sedimentary rock. The three types of sedimentary rocks are categorized as Organic, Clastic, and Chemical Sedimentary Rocks. Lime stone, clay, sandstone, etc. are some Sedimentary rocks.

The sediment particle size and fluctuation is the best indicator of the type of rock.

Thus the correct option is B.

You havent attached the choices so we cant tell u the answer

Answer:

I do not see the options but this is what I know.

Explanation:

At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE. In this case, the energy added to the liquid goes into breaking the bonds between the liquid molecules without causing the temperature to change. The same thing happens when a solid changes into liquid.

Answer:

A. - angle and number

Explanation:

(>-<)

The size of the crystal faces and the angle between them define the crystal system. Therefore, option (D) is correct.

What is a crystal system?

A crystal system indicates many classes of crystals, space groups, and lattices. In crystallography terms,  crystal system and lattice system are associated with each other. The crystals based on their point groups are divided into seven crystal systems.

The seven-crystal system is the Cubic, Tetragonal, Hexagonal, Orthorhombic, Monoclinic, Triclinic, and Rhomohedral systems. The classification of Seven Crystal Systems is depending upon their lattice and atomic structure.

The size and length of their surfaces which are known as ‘faces’ and sides, and the angles between them, define the shapes of crystals. The cubic crystal system is the most symmetrical as all the angles and the length of the edges is equal.

While the triclinic is the most unsymmetrical crystal system as all the lengths and the angles between faces are unequal.
