Grade 4 Earth science worksheet on human impact and protection of Earth's surface. Multiple-choice questions show how dirt roads cause erosion and how trees, jetties, and flexible building design reduce hazards. Fill-in items reinforce key vocabulary like erosion, jetties, earthquakes, and how scientists prepare for future natural events. Students consider how human choices shape Earth and how engineering can protect us from natural hazards in this Grade 4 capstone earth science worksheet.
Style:
Earth's Changing Surface
Part A: Multiple Choice
Circle the best answer for each question.
1. Building a new dirt road on a steep hill most likely causes
A) more soil erosion when it rains
B) fewer earthquakes
C) the rocks below to harden
D) rivers to disappear
2. Planting trees along a bare hillside helps protect the land because roots
A) make the soil heavier than water
B) stop earthquakes from happening
C) hold soil in place and slow runoff
D) create more wind erosion
3. A jetty is a long stone wall built into the ocean to
A) speed up beach erosion
B) block wave erosion and protect the beach
C) cause volcanoes
D) make new fossils
4. In earthquake zones, engineers design buildings that can
A) float on water
B) sway and bend without breaking
C) stop tectonic plates from moving
D) turn into volcanoes
Part B: Fill in the Blank
Write the correct answer on each line.
1. Cutting down forests for farms often increases soil erosion on hillsides.
2. Sea walls and jetties are structures engineers use to protect coasts from waves.
3. Adding plants whose roots hold soil is one way humans can prevent erosion.
4. Buildings in California are designed to be flexible because of earthquakes.
5. Studying past floods and quakes helps engineers prepare for future hazards.
