Question

question 23
which statement describes how sedimentary rocks are formed?
a. sediment is under high pressure deep underground.
b. sediment melts because of heat deep underground.
c. igneous rocks get worn away over time.
d. loose layers bond together over time.

Explanation:

To determine how sedimentary rocks are formed, we refer to the text: "Sedimentary rocks are formed at the surface of the Earth, either in water or on land. Sediments — such as fragments of rocks, minerals, or animal or plant material — build up in layers, creating this type of rock." And option D says "Loose layers bond together over time", which matches the description of sediments (loose materials) building up and bonding over time to form sedimentary rocks. Option A and B refer to processes related to igneous or metamorphic rocks (involving high pressure/heat underground melting, which is not sedimentary rock formation). Option C is about igneous rocks being worn away, not sedimentary rock formation.

Answer:

D. Loose layers bond together over time.
