d) sandstone

1. sedimentary rocks
2. how do sedimentary rocks form?

a) by heat and pressure
b) through erosion, deposition, compaction, and cementa
c) from lava cooling
d) by chemical reactions in the mantle

1. which of the following are sedimentary rocks?

a) sandstone
b) shale
c) limestone

Explanation:

Question 3:

Igneous rocks form from cooled magma/lava. Granite (intrusive igneous) and Basalt (extrusive igneous) are igneous. Marble is metamorphic, Sandstone is sedimentary.

Sedimentary rocks form via erosion (breaking rocks), deposition (sediments accumulate), compaction (sediments press together), and cementation (sediments bind). Heat/pressure forms metamorphic, lava cooling forms igneous, mantle reactions aren’t sedimentary formation.

Sedimentary rocks form from sediments. Sandstone (from sand sediments), Shale (from fine sediments), Limestone (from marine sediments) are sedimentary.

Answer:

a) Granite, b) Basalt
