Earths Features
The lava flows down the side of a volcano. Scientists want to predict which way the lava will flow next so that they can warn people and villages that may be in the way. Figure A shows two paths that the lava could take.
A The lava will flow down path W because it is a long path that can carry a lot of lava.
B The lava will flow down path X because it is a steep path that lets the lava move quickly.
C The lava will flow down path W because it is a flat path that provides space for the lava to spread out.
D The lava will flow down path X because it is a short path that lets the lava get to the ocean before it cools down.
B The lava will flow down path X because it is a steep path that lets the lava move quickly.
Using Figure B
A student claims that Hawaiian volcanoes formed in an unusual location.
Which statement best supports the student’s claim?
A. Volcanoes usually form in long chains, but the Hawaiian Islands have only a few volcanoes.
B. Volcanoes usually form near mountains, but the Hawaiian Islands are very far away from any mountains.
C. Volcanoes usually form at the edges of continents, but the Hawaiian Islands are in the middle of the ocean.
D. Volcanoes usually form over a short time period, but the Hawaiian Islands have taken millions of years to form.
C. Volcanoes usually form at the edges of continents, but the Hawaiian Islands are in the middle of the ocean.
Based on the pattern shown in Map 1, which is the most likely age of Kahoolawe?
A 1.0 million years old
B 2.5 million years old
C 3.0 million years old
D 4.5 million years old
A 1.0 million years old
Based on the pattern shown in Map 1, in which location would the next island most likely form?
A location W, because new islands form near the oldest island
B location X, because new islands form south of older islands
C location Y, because new islands form between older islands
D location Z, because new islands form east of older islands
D location Z, because new islands form east of older islands
How is lava flowing from a volcano most dangerous to humans?
A The lava can start fires, destroy buildings, and block roads.
B The lava can heat up the ocean and kill all the fish that humans eat.
C The lava can cover the land so that crops can no longer grow in that place.
D The lava can cause lakes in its path to boil and make the lakes too hot for humans to
swim in.
A .The lava can start fires, destroy buildings, and block roads.
