Earth's Layers
Which layer of the Earth lies directly beneath the crust and is made up of solid rock?
What is the mantle
Who is the scientist credited with proposing the Continental Drift Theory in the early 20th century?
Alfred Wegener
What is the name of the large sections of Earth's lithosphere that move and interact with each other?
tectonic plates
What is the name of the boundary where two tectonic plates move apart from each other?
divergent boundary
What bird cannot fly?

What is the outermost layer of the Earth called?
the crust
What evidence did Wegener use to support his Continental Drift Theory? name 2

What layer of the Earth do tectonic plates float on?
Provide 2 names
asthenosphere or upper mantle
At which type of boundary do tectonic plates slide past one another without creating or destroying crust?
transform boundary
What color is Panda Bear's skin?
Black
What is the name of the liquid layer of the Earth that surrounds the inner core?
What is the outer core
In the Seafloor Spreading Theory, what geological feature is formed where new oceanic crust is created?
Oceanic Ridge
What is the main driving source that moves the tectonic plates?
Convection Currents
What type of boundary is characterized by the movement of tectonic plates toward each other, often leading to volcanic activity?
convergent boundary
How many bones are in a Giraffe's neck?
7 - same as humans
What Layer is mostly made up of solid iron and nickel?
Inner Core
What phenomenon occurs when tectonic plates collide, leading to the formation of deep ocean trenches and volcanic arcs?
subduction
Which theory explains the movement of tectonic plates due to convection currents in the mantle?
The theory of plate tectonics
Which boundary type is responsible for the formation of mountain ranges, such as the Himalayas, when two continental plates collide?
convergent boundary
What is the only mammal that cannot jump?

How do scientists learn about the layers of the Earth, given that they cannot directly observe them?
studying seismic waves or sample drilling
What are the large, rigid plates that make up the Earth's lithosphere called, and how do their movements affect geological activity?
tectonic plates, and their movements can cause earthquakes, volcanic eruptions, and the formation of mountain ranges
Name the supercontinent that existed about 300 million years ago, which included most of the Earth's landmasses before they drifted apart.
Pangea
Describe the process that occurs at a plate boundary where one tectonic plate is forced down into the mantle beneath another plate.
subduction
