This landform is a large, flat region often great for agriculture.
(What are plains?)
This supercontinent existed 240 million years ago.
(What is Pangea?)
The name for rigid sections of Earth’s crust that move and interact.
(What are tectonic plates?)
These natural disasters are typically caused by large, undersea earthquakes.
(What are tsunamis?)
This shape of the valley is typically formed by rivers and streams.
(What is a V-shape?)
A high, flat region created by Earth's surface movement.
(What is a plateau?)
The term for Earth's outer, solid crust.
(What is the lithosphere?)
A plate boundary where two plates move apart (in opposite directions) often causing ridges
(What is a divergent boundary?)
These tools measure the magnitude of earthquakes.
(What is a seismograph?)
This type of valley is formed by melting glaciers.
(What is a U-shape?)
These natural features rise more than 2,000 feet above sea level.
(What are mountains?)
This theory explains the movement of continental landmasses across Earth.
(What is continental drift?)
A plate boundary where two plates grind past each other side-by-side.
(What is a transform boundary?)
The name for the location directly above an earthquake’s main shock.
(What is the epicenter?)
This landform covers one-third of Earth’s land area.
(What are plains?)
This landform is the base rock of an ancient mountain region, covering 50% of Canada.
(What is the Canadian Shield?)
This was the primary flaw in the early continental drift hypothesis.
(What is "continents were thought to drift due to Earth’s rotation?")
This is the most dangerous component of a volcanic eruption.
(What are gas and ash?)
This type of engineering helps buildings resist earthquake damage.
(What are flexible bases or bendable materials?)
Fertile valleys are important to civilizations for this reason.
(What is growing crops?)
These are depressions in the land, often fertile and taking "U" or "V" shapes.
(What are valleys?)
This series of volcanoes and earthquake zones surrounds the Pacific Ocean.
(What is the Ring of Fire?)
A boundary where plates push together, often creating mountains or volcanoes
(What is a convergent boundary?)
The most important response to a natural disaster.
(What is listening to warnings and having an evacuation plan?)
The processes that formed the Canadian Shield.
(What are plate tectonics, erosion, and glaciation?)
