Medium 1 challenges Grade 4 students to read evidence of Earth's changing surface in rock layers, fossils, and landforms. Fill-in items target older versus newer layers, sedimentary rock, and the meaning of canyons and deltas. The matching activity links four landforms to the slow or fast processes that built them. This Grade 4 worksheet supports classroom practice and homework review at home for stronger learning outcomes.
Style:
Earth's Changing Surface
Part A: Fill in the Blank
Write the missing word or number on each line.
1. In undisturbed rock layers, the older layers are usually on the bottom.
2. The preserved remains or traces of ancient living things found in rocks are called fossils.
3. A deep, narrow valley cut by a river over a long time is called a canyon.
4. Finding fossils of sea creatures on a mountain is evidence the area was once under the ocean.
5. A natural feature on Earth's surface, like a hill, valley, or mountain, is called a landform.
6. Mountains that form when two of Earth's plates push together and squeeze rock upward are called fold mountains.
7. When sediment piles up at the mouth of a river, the flat fan-shaped landform is called a delta.
8. A scientist who studies rocks, layers, and Earth's history is called a geologist.
9. Layers of rock that form when sediment is pressed and stuck together are called sedimentary rock.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
