Eli finds a rock with layers and smaller pieces of other rocks embedded in it.The rock is most likely

a) igneous
b) sedimentary
c) metamorphic
d) chemical

Sedimentary. Layers are a key feature of sedimentary rock, as younger layers are deposited atop older ones.

To determine the most likely type of rock Eli found, we need to consider the characteristics of each option.

a) Igneous rock is formed through the cooling and solidification of molten material (magma or lava). It typically does not have layers or embedded pieces of other rocks.

b) Sedimentary rock is formed when layers of sediment (such as sand, mud, or tiny fragments of rocks) build up and compress over time. The layers and smaller pieces of other rocks embedded in Eli's rock suggest a sedimentary origin. Therefore, this is a likely possibility.

c) Metamorphic rock is formed when existing rocks are subjected to high heat and/or pressure, causing them to undergo chemical and structural changes. While metamorphic rocks can sometimes have layers, they usually do not have smaller pieces of other rocks embedded in them.

d) Chemical rocks, also known as evaporite rocks, are formed from the evaporation of water containing dissolved minerals. They do not typically have layers or embedded pieces of other rocks.

Considering the given information, option (b) sedimentary is the most likely type of rock that Eli found.
