Section 1
This type of change happens slowly over time, like erosion and weathering
What is a gradual change?
These are the three main types of rocks.
What are igneous, sedimentary, and metamorphic rocks?
This scientist proposed the theory of continental drift.
Who is Alfred Wegener?
These are preserved remains or traces of living organisms
What are fossils?
These are the four main layers of Earth.
What are crust, mantle, outer core, and inner core?
This is the point on Earth’s surface directly above an earthquake’s origin.
What is the epicenter?
These are the building blocks of rocks.
What are minerals?
This was the name of the supercontinent that once included all land.
What is Pangaea?
This type of rock most commonly contains fossils.
What is sedimentary rock?
This type of rock forms from compacted sediments.
What is sedimentary rock?
This instrument records earthquake vibrations.
What is a seismograph?
This scale is used to measure mineral hardness.
What is the Mohs Scale of Hardness?
These are the three types of plate boundaries.
What are divergent, convergent, and transform boundaries?
This type of fossil includes footprints or tracks left behind.
What is a trace fossil?
These are the four types of evidence Wegener used.
What are fossils, rock formations, mountain ranges, and glacial deposits?
These waves travel through Earth during an earthquake.
What are seismic waves?
These are the six properties used to identify minerals.
What are colour, lustre, streak, cleavage, fracture, and hardness?
This is where most earthquakes and volcanoes occur.
What are plate boundaries?
This must happen quickly to help an organism become a fossil.
What is burial by sediment?
This is the movement of sediment from one place to another.
What is erosion?
This type of change happens quickly and can cause major damage, like earthquakes or volcanoes.
What is a sudden change?
This type of rock forms when magma or lava cools.
What is igneous rock?
This happens when two tectonic plates collide.
What is a convergent boundary?
This law states that older rock layers are found below younger ones.
What is the law of superposition?
These are the most common types of fossils.
What are fossils of hard parts, like bones and shells?
