Answer:
The correct order is
1. Weathering
2. Erosion and Transportation
3. Deposition
4. Sedimentation
Explanation:
The process involved in the formation of sedimentary rocks are –
a) Weathering – In this a preexisting rock is weathered into fine particles or pieces
b) Erosion & Transportation – the weathered fine particles are further disintegrated into fine powder so that they can be easily carried away by the force of wind, water , glaciers etc.
c) Deposition – The transported soil is deposited layer by layer with oldest layer at the bottom ,
d) Sedimentation – It is the compaction of loosely deposited soil to form silica and calcite gel.
Answer:
Explanation:
There are majorly five steps involved in the formation of sedimentary rocks -
a) Weathering - At this stage the pre-existing rocks are broken down by natural forces.
b) Erosion and transportation - The weathered rock pieces or soil is carried by air, water , ice (glaciers) etc. for deposition at any place
c) Deposition - At this stage, the carried away soil and smaller rock fragments are dumped at one place for piling up
d) Lithification - This stage consists of two steps a) Compaction and b) Cementation
In compaction , excess water is expelled out of piled up materials by the virtue of their own weight and in cementation chemical forces build up to form sediment deposits.
Hence the correct order of sedimentary rock formation is
