Hard 2 deepens plate tectonics for Grade 4 with mid-ocean ridges, subduction, the Ring of Fire, hot spots, and folded rock. Multiple-choice and fill-in items push students to use evidence such as ocean fossils on mountains and to sort fast changes from slow ones using clear plate-tectonics reasoning. This Grade 4 worksheet supports classroom practice and homework review at home for stronger learning outcomes.
Style:
Earth's Changing Surface
Part A: Multiple Choice
Circle the best answer for each question.
1. Which type of plate boundary is MOST likely to build a tall mountain range on a continent?
A) Two plates pushing together
B) Two plates pulling apart
C) Two plates sliding past each other
D) Two plates standing perfectly still
2. Why are scientists confident that Earth's surface has changed over time?
A) They find ocean fossils on mountaintops
B) Mountains are always perfectly smooth
C) Rocks never change once they form
D) Rivers only flow uphill
3. Which list shows ONLY fast changes to Earth's surface?
A) Earthquake, volcanic eruption, landslide
B) Weathering, erosion, deposition
C) Glacier, fossil, canyon
D) Sediment, delta, rock layer
4. Two plates pull apart under the ocean. What is MOST likely to form there?
A) A mid-ocean ridge with new rock
B) A tall fold mountain on land
C) A canyon carved by a river
D) A glacier sliding down a hill
Part B: Fill in the Blank
Write the correct answer on each line.
1. When one ocean plate slides beneath another plate, the process is called subduction.
2. The Ring of Fire is a zone around the Pacific Ocean famous for many volcanoes and earthquakes.
3. Layers of rock that have been bent or wrinkled by plate pushing are said to be folded.
4. A scientist who studies how plates move and shape Earth is studying plate tectonics.
5. Volcanic islands like Hawaii are built when lava cools and hardens above a hot spot in the mantle.
