Question 1

True or false: By 1900, the bison that once roamed the Great Plains in the millions had been reduced to fewer than 1,000 surviving animals.

Accepted Answer

True. Once 30 million strong, bison were hunted to near extinction—by 1889 fewer than 1,000 survived, mostly in protected areas.

Question 2

True or false: The Great Plains are known for their extensive forests.

Accepted Answer

False. The Great Plains are primarily grasslands and prairies with few trees. Dense forests occur in regions like the Pacific Northwest and the Northeast.

Question 3

True or false: Prairie dog towns on the Great Plains can cover hundreds of acres.

Accepted Answer

True. Black-tailed prairie dog colonies, called towns, have been found spanning over 1,000 acres, with complex burrow networks.

Question 4

True or false: The Great Plains are located entirely within the United States.

Accepted Answer

False. The Great Plains extend north into Canada, covering parts of Alberta, Saskatchewan, and Manitoba, so they are not exclusive to the United States.

Question 5

True or false: The Great Plains stretch into Canada, covering parts of three provinces.

Accepted Answer

True. The Great Plains extend north into Alberta, Saskatchewan, and Manitoba, encompassing a large swath of the Canadian Prairies.

Question 6

True or false: The Great Plains were home to millions of bison before European settlement.

Accepted Answer

True. Historians estimate 30 to 60 million bison roamed the Great Plains before the 19th century, forming the largest land mammal herds in North America.

Question 7

True or false: The Ogallala Aquifer, under the Great Plains, is one of the largest freshwater aquifers in the world.

Accepted Answer

True. Spanning eight states, the Ogallala supplies about 30% of U.S. irrigation water but is being depleted faster than it recharges.

Question 8

True or false: The Great Plains receives more annual rainfall than the Amazon rainforest.

Accepted Answer

False. The Amazon gets over 2,000 mm of rain yearly; the Plains average only 300–500 mm, classifying them as semi-arid.

Question 9

True or false: The Dust Bowl of the 1930s was caused entirely by a severe drought.

Accepted Answer

False. Over-farming and removal of native grasses, combined with drought, led to massive dust storms—human activity was a key factor.

Question 10

True or false: The Great Plains extend across multiple U.S. states and into the Canadian provinces of Alberta, Saskatchewan, and Manitoba.

Accepted Answer

True. The Great Plains cover portions of 10 U.S. states and 3 Canadian provinces, including Alberta, Saskatchewan, and Manitoba.

Question 11

True or false: The Great Plains contain the Ogallala Aquifer, one of the largest underground water sources globally.

Accepted Answer

True. The Ogallala Aquifer underlies parts of eight U.S. states in the Great Plains and supplies irrigation for large-scale agriculture. It is among the world's largest aquifers.

Question 12

True or false: The Great Plains receive abundant rainfall throughout the year.

Accepted Answer

False. The Great Plains have a semi-arid to arid climate with low annual rainfall, typically 10–20 inches, contrasting with wetter regions like the Southeast.

Question 13

True or false: More than 90% of the original Great Plains grasslands remain intact today.

Accepted Answer

False. Approximately half of the Great Plains have been converted to cropland or other uses, leaving well below 90% intact. The original grassland ecosystem has been heavily altered by agriculture.

Question 14

True or false: The Great Plains were formed by massive volcanic eruptions millions of years ago.

Accepted Answer

False. The Great Plains were built from sediment eroded from the Rocky Mountains and deposited by ancient seas, not volcanic activity. Volcanic landscapes are found elsewhere.

Question 15

True or false: The Great Plains were once home to a vast inland sea called the Western Interior Seaway.

Accepted Answer

True. During the Cretaceous period, a shallow sea covered much of the Plains, leaving behind marine fossils like those of mosasaurs.

Question 16

True or false: The Great Plains were once covered by a shallow inland sea called the Western Interior Seaway.

Accepted Answer

True. During the Cretaceous period, a vast sea covered much of central North America, depositing sediments that later formed the Great Plains. This is well-documented in geology.
