The table lists some physical properties of two objects. Based on their properties, which of the objects is most likely a metal?
Object 1, because it is a solid that is less dense than water
Object 2, because all metals float in water
Object 2, because metals conduct thermal energy and electricity
Object 1, because it can be used to provide insulation for thermal energy
Students are investigating properties of objects. They observe four objects and record observations for each object in the table. Based on the students' observations, which of these tables properly identifies the objects?
A student measured out 10 mL of four clear liquids and added one drop of a different-colored dye to each liquid. One of the liquids was water. The student then carefully poured each liquid into a graduated cylinder and let the mixture settle for 30 minutes. The student observed that the liquids had separated into layers, as shown in the diagram. Which of these procedures would help the student identify the layer of water?
Stir the liquids, let them settle, and then identify the bottom layer as water
Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water
Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water
Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water

Ricky created a model of a glacier to help explain how glaciers change the surface of 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 Ricky's model explain how glaciers change Earth's surface?
The rocks and sand contained in most glaciers create grooves in Earth's surface.
The rocks and sand contained in some glaciers fill the grooves in Earth's surface.
Pure glaciers and glaciers that contain rocks and sand affect the Earth in exactly the same way.
The water in pure glaciers cools Earth's surface.
Hailey and her brother made a sand castle at the beach. Hailey slowly poured water on top of the sand castle. Some of the sand ran down the side of the castle with the water. What type of phenomenon did Hailey demonstrate?

Erosion by heat.
Weathering by water.
Erosion by water.
Which of the following is not an example of erosion?
