Laci sees this picture of a volcano. How does Laci know that igneous rock is being formed?
The volcano is undergoing great heat and pressure.
The lava flowing down the sides of the volcano will cool.
The molten magma flowing down the sides of the volcano will harden.
The lava erupting from the volcano contains sediments that will harden.
Sariah knows that granite is a rock that is made up partly of large crystals of the minerals quartz and feldspar. What can Sariah say about granite and all other rocks?
All rocks have pieces of granite in them.
They are all made up of one or more minerals.
They all contain the minerals quartz and feldspar.
Most rocks are made up of large quartz crystals.
Wendell's backyard has pieces of slate rock that are used as a footpath. Slate is a metamorphic rock that splits into flat pieces. What natural forces in Earth cause the formation of slate?
Molten magma deep inside Earth cools and slowly hardens over time.
Great heat and pressure cause the minerals to line up in parallel layers.
Lava erupts and runs down the side of a volcano, then cools and hardens.
Sediments of once living things are deposited over time and become cemented.

Dana uses a copper penny and a steel nail to test the hardness of some minerals. She cannot scratch quartz with the steel nail. She can scratch calcite with the copper penny. She can scratch an unknown mineral with the penny but not with the nail. Dana knows that the unknown mineral is not calcite or quartz. What can Dana say about the unknown mineral?
It is softer than both calcite and quartz
It is harder than both calcite and quartz
It is softer than calcite, but harder than quartz
It is harder than calcite, but softer than quartz
