Which statemen 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.

## Step 1<br />Sedimentary rocks are formed through a process called lithification. This process involves the deposition of sediment, which is then compacted and cemented over time to form solid rock.<br /><br />## Step 2<br />Option A describes the formation of metamorphic rocks, not sedimentary rocks. Metamorphic rocks are formed when sediment is under high pressure deep underground.<br /><br />## Step 3<br />Option B describes the process of melting, which is not how sedimentary rocks are formed. Instead, this process is how igneous rocks are formed.<br /><br />## Step 4<br />Option C describes the weathering of igneous rocks, which is a process that leads to the formation of sediment, but not sedimentary rocks.<br /><br />## Step 5<br />Option D correctly describes the process of lithification, where loose layers of sediment bond together over time to form sedimentary rocks.
