The picture below shows the changes that happened to a rock at different times of day and at different temperatures. If 0°C is the freezing point of water, then which of the following is the most likely way that the soil around these rocks was formed over time?

• The soil was formed mostly from pieces of rock melting as water inside the rocks froze and then heated up over time.

• The soil was formed mostly by the rocks breaking themselves apart to allow water to pass through and prevent freezing.

• The soil was formed mostly by the rocks drying up the soil by preventing light and water from reaching the soil.

• The soil was formed mostly from pieces of rock breaking apart as water inside the rocks froze, expanded, and broke apart over time.

Noah created a model of a glacier to explain how glaciers change the surface of the Earth. He froze two large blocks of ice. One block was pure water. The other was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Noah's model explain how glaciers change Earth's surface?

• The water in pure water glaciers does not affect Earth's surface, and ones with rocks and sand create mountains.

• The rocks and sand contained in most glaciers fill the grooves in Earth's surface.

• The rocks and sand contained in most glaciers create grooves in the Earth's surface.

• The water in pure water glaciers builds ice mountains on Earth's surface, and ones with rocks and sand destroy Earth.

Which of the following BEST describes how ice causes slow changes to Earth’s surface through weathering, erosion, and deposition?

• Ice causes the land to heat up quickly, leading to the formation of deserts.

• Ice moves across the land, scraping away rock and soil, and depositing sediments when it melts.

• Ice releases chemicals that dissolve rock and form underground caves.

• Ice moves in a circular pattern, creating large hills and mountains.

The picture below shows a lake that was formed because of the movement of a glacier. Which of the following BEST explains the slow changes that happened to this environment because of the glacier?

• The glacier pushed rock and sand as it moved, creating a landform that trapped the glacier, and ice from the glacier melted to form a lake.

• The glacier melted entirely and flowed down the mountainside, filling a large hole made from an object that hit Earth years ago.

• The movement of the glacier caused strong winds that made large amounts of water fall in this area and form a lake.

• The movement of the glacier weathered the ground below it and caused water to rise from the ground and form a lake.
