Question

sand grains in a sedimentary rock. which two processes cause sand particles to form sandstone? erosion and heating compaction and cementation cementation and cooling

Explanation:

Sandstone is a sedimentary rock formed when sand - sized grains of sand are cemented together. Compaction reduces the pore space between sand particles and cementation binds the sand grains with minerals. Erosion and weathering break down rocks into sediments but are not the processes that form sandstone from sand particles directly. Cooling is more related to igneous rock formation from magma or lava.

Answer:

compaction and cementation
