Overview: Galapagos, p. 75

1			Examine the islands carefully. What geologic/geographic features are these islands constructed from?
			A)	Coral reef atolls
			B)	Volcanoes
			C)	Sand bars
			D)	Landslides
			E)	Uplifted blocks of seafloor
2			What country claims the Galapagos?
			A)	The United States of America
			B)	Panama
			C)	Columbia
			D)	Ecuador
			E)	Peru
3			What is the largest island in the archipelago?
			A)	Isla Fernandina
			B)	Isla Isabella
			C)	Isla Guy Fawkes
			D)	Isla Bartolome
			E)	Isla Tortuga
4			Measured from the center of the island group, how far is it from the Galapagos to the mainland of South America?
			A)	400 km
			B)	700 km
			C)	1000 km
			D)	1300 km
			E)	1600 km
5			Why was it important for Darwin's studies that the Galapagos is separated by such a great distance from the mainland?
			A)	Darwin was seeking isolation because he did not want to be bothered while undertaking such an ambitious classification project.
			B)	Darwin wanted to ensure that the island was unlikely to have been studied by others prior to him.
			C)	It wasn't actually the distance that was important to Darwin, but rather that the ocean currents were favorable for his trips back and forth to the mainland.
			D)	The weather was much more favorable on the island than on the mainland, making it an ideal location for scientific study.
			E)	The distance makes it more difficult for immigrant species to reach the islands, and consequently, a large portion of resident species evolved in place and occur nowhere else.
