Problem Overview:

The task involves completing a concept map related to Plate Tectonics. The goal is to fill in the blanks with appropriate terms from the provided list and explain the relationships between the concepts.

Provided List of Terms:

- mid-ocean ridges
- volcanic islands
- rift valleys
- deep-sea trenches
- volcanic mountains
- convergent
- divergent
- transform

Concept Map Structure:

The concept map is divided into three main sections:
1. Mid-Ocean Ridges: Includes "rift valleys."
2. Volcanic Islands: Includes "volcanic mountains."
3. Major Earthquakes: Includes "deep-sea trenches."

Each section is associated with a type of plate boundary:
- Convergent: Plates move toward each other.
- Divergent: Plates move away from each other.
- Transform: Plates slide past each other.

Directions:

1. Fill in the blanks in the sentences at the top of the page.
2. Complete the concept map using the terms in the list below.

Step-by-Step Solution:

#### Part 1: Filling in the Sentences
1. Earth's crust and upper mantle are broken into sections called...
- These sections are known as plates.
- Answer: b. plates

2. The collision of one continental plate with another may produce...
- When two continental plates collide, they push against each other, causing the formation of mountains.
- Answer: b. mountains

3. New ocean crust is formed at a...
- New ocean crust is created at mid-ocean ridges, where magma rises and solidifies.
- Answer: b. mid-ocean ridge

4. A rift valley can form where two continental plates are...
- A rift valley forms when two continental plates move apart, creating a gap that fills with magma.
- Answer: a. moving apart

5. Where Earth's plates move, they may slide alongside one another, pull apart, or...
- Plates can also collide (or converge) when they move toward each other.
- Answer: b. collide

#### Part 2: Completing the Concept Map

The concept map relates specific features (e.g., mid-ocean ridges, volcanic islands, deep-sea trenches) to their corresponding plate boundaries (convergent, divergent, transform). Let’s fill in the blanks step by step.

1. Mid-Ocean Ridges:
- Mid-ocean ridges are associated with divergent plate boundaries, where plates move apart.
- Features include rift valleys.
- Answer for 6: divergent
- Answer for 8: rift valleys

2. Volcanic Islands:
- Volcanic islands are formed at transform plate boundaries, where plates slide past each other, often along with volcanic activity.
- Features include volcanic mountains.
- Answer for 7: transform
- Answer for 9: volcanic mountains

3. Deep-Sea Trenches:
- Deep-sea trenches are associated with convergent plate boundaries, where one plate subducts beneath another.
- Features include major earthquakes.
- Answer for 10: convergent
- Answer for 11: deep-sea trenches

Final Answers:

1. b. plates
2. b. mountains
3. b. mid-ocean ridge
4. a. moving apart
5. b. collide

For the concept map:
- 6: divergent
- 7: transform
- 8: rift valleys
- 9: volcanic mountains
- 10: convergent
- 11: deep-sea trenches

Explanation:

- Divergent Boundaries: Occur where plates move apart, forming mid-ocean ridges and rift valleys.
- Convergent Boundaries: Occur where plates collide, forming deep-sea trenches and major earthquakes.
- Transform Boundaries: Occur where plates slide past each other, often leading to volcanic islands and volcanic mountains.

Final Answer:

\boxed{b, b, b, a, b, \text{divergent}, \text{transform}, \text{rift valleys}, \text{volcanic mountains}, \text{convergent}, \text{deep-sea trenches}}
