Landforms Science Review

Fossils - Clues from the Past
Fossils are evidence of past life.
Scientists study fossils to learn about how land and environments have changed over time.
Different rock layers contain different fossils—some are older and some are newer.
3
Open Ended
A scientist finds a shark tooth fossil in the middle of a desert. What does this tell us about the past?
📝What might the land have looked like millions of years ago?
4
Multiple Choice
Which fossil would tell scientists that a place was once a tropical rainforest?
Fish fossil
Fern leaf fossil
Dinosaur footprint
Seashell fossil
5
The oldest rock layers are at the bottom.
The youngest rock layers are at the top.
Fossils in lower layers are older than fossils in higher layers!
Rock Layers Tell a Story
6
Multiple Choice
Which rock layer is the oldest?
Bright Angel Shale
Hermit Shale
Coconino Sandstone
Kaibab Limestone
7
Open Ended
🎯 Challenge: Imagine you are a paleontologist (a scientist who studies fossils). Where would you look for the OLDEST fossils?
8
Multiple Choice
A scientist finds a fossil in the bottom layer of a canyon. What does this mean?
The fossil is the youngest.
The fossil is the oldest.
The fossil just formed.
The fossil is not real.

Fast-moving water carries more rocks.
Slow-moving water carries less.
Larger sediments are deposited FIRST. Smaller sediments are deposited last.
Moving Water

🌊 Fast rivers carry big rocks 🪨
💦 Slow rivers carry small particles 🏝️
🏔️ Steep slopes = more erosion
🏞️ Flat land = more deposition
The Power of Moving Water
13
Multiple Choice
A river is carrying sand, pebbles, and boulders. The water begins to slow down. Which material will settle first?
Sand
Pebbles
Boulders
All settle at the same time.
14
Open Ended
Why do beaches have soft sand instead of big boulders?
15
Wind moves sand and creates sand dunes.
Wind
Water shapes river and valleys.

How do Landforms Change?
16
Multiple Choice
Which factor affects how much erosion happens in a river?
The number of fish in the river
The speed of the water
The color of the rocks
The shape of the riverbank
17
Multiple Choice
Which force moves sand dunes?
Water
Wind
Volcanoes
Earthquakes
18
How does soil form?
Rocks break down into smaller pieces through weathering.
Dead plants and animals add nutrients.
Different places have different soils depending on weather, plant life, and rock types.
19
Multiple Choice
Which of the following help create soil? (You can choose more than one)
Ice and wind
Water and plants
Sunlight and temperature
People and animals
20
Open Ended
A student wants to test how slope affects erosion. She pours the same amount of water on two different ramps.
Ramp A: Steep Slope
Ramp B: Standard or Gentle Slope.
Which ramp will cause more erosion? Why?
