Step-by-step solution for: Plate Boundaries, Volcanoes, and Types of Volcanoes - Worksheet ...
Here are the answers to the questions on the worksheet.
Q.1 Fill in the blanks:
a) tectonic plates
b) plate boundary (or fault)
c) less
d) magma
Q.2 Label the type of plate boundaries:
* Top diagram (arrows moving apart): Divergent
* Middle diagram (arrows sliding past): Transform
* Bottom diagram (arrows crashing together): Convergent
Q.3 Which statement is false?
The false statement is b). (Volcanoes are found all over the Earth, not just in our solar system—though technically they exist elsewhere, in the context of Earth science, saying they are *only* found on Earth in our solar system is often considered the distractor, but actually, looking closer at option b: "Volcanoes are only found on Earth in our solar system." This is scientifically false because there are volcanoes on Mars and Venus. However, usually, these tests look for the "obvious" error. Let's look at c: "Many volcanoes are found on the ocean floor." This is true. d: "The body of molten rock... is known as a magma chamber." This is true. So b is definitely the false one because other planets have volcanoes too.)
*Correction*: Actually, let's re-read carefully.
a) Volcanoes change surface constantly. (True)
b) Volcanoes are only found on Earth in our solar system. (False - Io, Mars, and Venus have them).
c) Many volcanoes are found on the ocean floor. (True)
d) The body of molten rock that feeds a volcano is known as a magma chamber. (True)
Answer: b)
Q.4 Which term is defined as an opening in the Earth's crust where molten rock and gases have erupted?
Answer: c) Volcano
Q.5 Which statement is false?
a) Divergent, convergent, and transform are the three major types... (True)
b) An example of a convergent plate boundary is the Pacific Ring of Fire. (True)
c) An example of a transform plate boundary is the San Andreas Fault. (True)
d) Volcanoes mostly occur at transform boundaries. (False - They mostly occur at divergent and convergent boundaries).
Answer: d)
Q.6 Label the parts of a volcano:
* Top center (pool of lava): Crater
* Left side (underground pool): Magma chamber
* Center vertical tube: Main vent
* Right side smaller tube: Secondary vent
* Material flying out top: Lava (once it exits) or Ash/Gas
* Layers on the side: Ash, dust, steam and gas (or layers of lava/ash)
*(Note: Based on the word bank provided: Magma chamber, Lava, Secondary vent, Crater, Main vent, Dust, ash, steam and gas)*
Q.7 \_\_\_\_\_ volcano is erupting or has shown signs that it may erupt in the near future.
Answer: b) Active
Q.8 \_\_\_\_\_ volcano has not erupted in a long time, but it might in the future.
Answer: c) Dormant
Q.9 \_\_\_\_\_ volcano has erupted thousands of years ago and is not expected to erupt again in the future.
Answer: d) Extinct (Note: The options list "Passive" as d, but standard science terms use Extinct. Looking at the options provided in Q9: a) Dormant, b) Active, c) Passive? Wait, the image cuts off the options for Q9 slightly, but typically the third type is Extinct. Let's look at Q7/Q8/Q9 options again.
Q7 options: a) Dormant, b) Active, c) Passive, d) Extinct? No, Q7 lists a) Dormant b) Active c) Passive d) Extinct is likely cut off or implied.
Let's look at the text definitions:
- Erupting/near future = Active.
- Not erupted in long time/might in future = Dormant.
- Erupted long ago/not expected again = Extinct.
Looking at the visible options for Q9: a) Dormant, b) Active, c) [Cut off], d) Passive.
Usually, "Extinct" is the correct term. If "Extinct" isn't an option, sometimes old worksheets use different terminology, but "Extinct" is the scientific standard. Assuming standard curriculum:
Q7 Answer: Active
Q8 Answer: Dormant
Q9 Answer: Extinct (If "Extinct" is option C or D hidden/cut off. If strictly choosing from visible words, none fit perfectly except potentially a mislabeled "Passive", but Extinct is the right word).
Crossword Puzzle Answers:
Across:
4. EXTINCT (State of volcanoes that erupted thousands of years ago...)
7. CINDER CONE (Tall, cone-shaped volcano made of alternating layers... wait, Cinder cones are usually just cinders. Stratovolcanoes/Composite are alternating layers. Let's check clue 7 again: "Tall, cone-shaped volcano that is made of alternating layers of lava and ash." This defines a COMPOSITE or STRATO volcano. Given the space, maybe STRATOVOLCANO? Or just COMPOSITE? Let's check Down clues to intersect.)
10. SHIELD (A small, steep-sided volcano... wait. Shield volcanoes are broad and gently sloping. Cinder cones are steep. Clue 10 says "small, steep-sided volcano that erupts gas-rich, basaltic lava." That is a CINDER CONE. But Clue 7 described alternating layers which is Composite. Let's re-read Clue 10 carefully. "A small, steep sided volcano..." -> CINDER.
Let's re-evaluate Clue 7: "Tall, cone-shaped... alternating layers". This is COMPOSITE.
Let's re-evaluate Clue 4: EXTINCT.
12. VENT (An opening in the Earth's crust...)
14. LAVA (The body of molten rock that flows...)
