8th Grade Earth and Space Science Concepts

Imagine the Earth as a giant jawbreaker candy, and you're on a sweet adventure with Annie and Jaylen! What are the four main layers of the Earth that you would "taste" as you journey to the center?

• Crust, Mantle, Outer Core, Inner Core

• Crust, Mantle, Inner Core, Outer Core

• Crust, Outer Core, Mantle, Inner Core

• Mantle, Crust, Outer Core, Inner Core

Maddy and Zac are on a quest to discover Earth's secrets! Can you help them by answering this: What percentage of the Earth's mass does the crust make up?

• 0.5%

• 1%

• 2%

• 5%

Imagine you're on an adventure with Annie, Khloe, and Garrison, exploring the mysteries of the Earth's surface! Which part of the Earth's crust is like a thick, cozy blanket made mostly of lighter rocks like granite?

• A) Oceanic crust

• B) Continental crust

• C) Upper mantle

• D) Lower mantle

Imagine you're on a journey to the center of the Earth with Clara, Garrison, and Maddy. As you travel through the layers, you discover the mantle. Can you guess what percentage of Earth's volume this massive layer occupies?

• 50%

• 84%

• 25%

• 10%

Imagine you're on an adventure to the center of the Earth with Zac, Amberly, and Ayden. What do you think the outer core of the Earth is made of?

• Solid iron and nickel

• Liquid metal, mostly iron and nickel

• Molten rock

• Solid rock

Imagine you're an astronaut like Maddy, exploring the vast universe! What role does the Earth's magnetic field, generated by the outer core, play in your cosmic adventure?

• It causes earthquakes

• It protects us from harmful solar radiation

• It creates new crust

• It forms mountain ranges

Lucas and Ellyn are on a journey to the center of the Earth! They discover that the inner core is composed primarily of which material?

• Iron and nickel

• Silicon and oxygen

• Magnesium and aluminum

• Carbon and hydrogen

Imagine you're on a thrilling adventure with Amberly, Garrison, and Clara, exploring the dynamic world of tectonic plates! What exciting event occurs at convergent boundaries when these massive plates crash into each other?

• They move apart

• They slide past each other

• They form mountains or cause subduction

• They remain stationary

Hey Garrison and Ava, can you tell me what a transform boundary is? Imagine you're explaining it to Zaven, who loves learning about tectonic plates. Can you also give an example?

• A transform boundary is a type of fault whose relative motion is predominantly horizontal, in either sinistral or dextral direction. An example is the San Andreas Fault in California.

• A transform boundary is a type of fault where two tectonic plates move away from each other. An example is the Mid-Atlantic Ridge.

• A transform boundary is a type of fault where two tectonic plates move towards each other. An example is the Himalayas.

• A transform boundary is a type of fault where one tectonic plate moves over another. An example is the Andes.

Jaylen and Clara are on a geology adventure! They discover two main types of igneous rocks. Can you help them identify these types?

• Clastic and Chemical

• Intrusive and Extrusive

• Foliated and Non-foliated
