Hard 1 introduces Grade 4 students to plate tectonics. Multiple-choice items ask what happens when plates push, pull, or slide, and fill-in clues cover tectonic plates, faults, trenches, and volcanoes. Students learn how the slow motion of giant rock slabs causes most mountains, earthquakes, and eruptions on Earth. 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. Earth's outer layer is broken into large pieces that slowly move. What are these pieces called?
A) Tectonic plates
B) Sediment layers
C) Glaciers
D) Volcanoes
2. What usually happens when two tectonic plates push directly into each other on land?
A) Mountains form as rock is pushed upward
B) A flat plain forms quickly
C) The plates disappear into the air
D) A new ocean forms between them
3. What forms when two plates pull apart from each other on land?
A) A rift valley with a deep crack
B) A tall fold mountain
C) A sandy beach
D) A canyon carved by a river
4. California's San Andreas Fault is famous because two plates ___ each other along it, often causing earthquakes.
A) slide past
B) stack on top of
C) freeze together with
D) melt into
Part B: Fill in the Blank
Write the correct answer on each line.
1. The large moving pieces of Earth's outer layer are called tectonic plates.
2. When plates push together and one bends down under the other, the deep crack underwater is called a trench.
3. A long crack in Earth's crust where plates can move past each other is called a fault.
4. Mountains, volcanoes, and earthquakes are mostly caused by the slow motion of Earth's plates.
5. When melted rock from inside Earth pushes up through a plate boundary and erupts, it builds a volcano.
