Answer, then tap to leap the frozen ridge.
In a cliff, a rock layer holding fern fossils lies below a layer holding ocean shell fossils. What do these layers tell you about this place?
Two streams flow over the same kind of soil. One moves slowly and the other rushes downhill. Which stream wears away and carries off more soil?

When a stream slows down, it drops some of the sediment it has been carrying.
A class wants to find out whether a layer of gravel slows erosion on a soil slope. What plan makes this a fair test?

A class marks every earthquake and volcano reported in one year onto a world map. What pattern do their marks show?
A town heats its homes by burning natural gas. Why do scientists call natural gas a nonrenewable resource?

A city replaces part of its coal-burning power plant with a wind farm. What environmental effect should the city expect?

A town beside a river floods almost every spring. What is a realistic goal for engineers working on this natural hazard?

A river empties fresh water into the sea, forming an estuary. How does the estuary's water compare with water in the open ocean?

A team must build a model bridge that holds a heavy book and uses no more than 20 straws. Which part of the task is a constraint?

Waves are washing away a town's beach. A stone sea wall would work but costs far more than the town can spend. Planted beach grasses hold sand and fit the budget. Which solution should the town choose?

A team tests a clay model wall and water leaks through the spot where two pieces meet. What should the team do next?

After a rain shower, a puddle on the playground blacktop is gone by the next sunny afternoon. Where did the puddle's water go?
Water vapor rises from the ocean and cools high in the sky, where it collects into the tiny water droplets that make up a cloud. What is this cooling and clumping of water vapor called?
A weather report says today will be sunny with a high of 75 degrees. A textbook says the region usually has hot, dry summers and mild, wet winters. Which statement describes the region's climate rather than its weather?
A desert town has hot, dry summers year after year, but on one August afternoon it gets an unusual downpour of rain. Which event is an example of weather, not climate?
Which process breaks a large rock into smaller pieces without moving them away?
Which process moves sand, soil, or rock from one place to another?
When a river drops sand at the inside of a bend, which process is happening?
Wind can cause erosion by carrying tiny pieces of sand and soil.
Which landform is most likely made by flowing water slowly cutting into rock over a long time?
Scientists find fossils of palm trees in rock in a very cold, icy place. What do the fossils tell them about that place long ago?
A fossil is usually evidence of an animal or plant that is still alive today.
Which tool would best help students compare the heights of different landforms in an area?
On a topographic map, contour lines that are very close together usually show a slope that is what?

Which event happens when huge blocks of rock deep underground suddenly slip and shake the ground?
Which natural hazard can bring very strong winds, heavy rain, and flooding near coasts?
People can completely stop all earthquakes by building stronger buildings.
What is one reason engineers test different solutions to reduce flooding?
A farm's dry, bare soil blows away on windy days. Which design would most likely slow this erosion?
Which solution is designed to reduce damage from earthquakes?
A levee is a structure that can help hold back floodwater.
Which question should engineers ask first when solving a problem about landslides near homes?
Which statement describes a constraint in an engineering design challenge?
Why do scientists study patterns of past earthquakes, floods, or volcanic eruptions?
Soil is made of tiny bits of broken rock mixed with which other material?
Water freezing in cracks can break rock apart because ice expands.
Which is the best example of using a model to test an erosion solution?
Hot melted rock pours out of an opening in the ground again and again. It cools and hardens in layers over a long time. Which landform does this build?
Which statement best compares fast and slow changes to Earth's surface?
