Question

1. choose the correct answer.

why do we see sedimentary rocks more often than igneous and metamorphic rocks?
because they are intrusive
because they are the rocks that line the surface of our planet
because they are extrusive
because they are the rocks found in the ocean

1. choose the correct answer.

sedimentary rock is often called lithified rock, which means ____.
materials turned softer
materials turned to stone
lithium
bumpy

Explanation:

Sub - Question 1

To determine why sedimentary rocks are seen more often, we analyze each option:

• Option "because they are intrusive": Intrusive refers to igneous rocks that cool below the surface, so this is incorrect.
• Option "because they are the rocks that line the surface of our planet": Sedimentary rocks form from sediment at the Earth's surface (like in oceans, rivers, on land), so they are more likely to be exposed at the surface compared to igneous (many deep - formed) and metamorphic (formed under pressure/heat deep in the Earth) rocks.
• Option "because they are extrusive": Extrusive is for igneous rocks that cool on the surface, so this is incorrect.
• Option "because they are the rocks found in the ocean": While sedimentary rocks can be in the ocean, they are also on land, and this doesn't fully explain why they are seen more often overall.

The term "lithified" comes from "lithos" which means stone. So we analyze the options:

• Option "materials turned softer": Lithification involves compaction and cementation which harden materials, not soften them.
• Option "materials turned to stone": This matches the meaning of lithification (turning sediment into rock).
• Option "lithium": Lithium is a chemical element, not related to lithification.
• Option "bumpy": Bumpy is a description of texture, not related to lithification.

Answer:

B. because they are the rocks that line the surface of our planet
