The map below shows the present-day positions of the continents. Points A through D represent locations on Earth’s surface. The location of New York State on the North American continent is indicated.
Which letter best represents the inferred position of the New York State region on Earth at the end of the Devonian Period?
The X on the map below indicates the region where the state of Washington is located on the present-day North American continent.
During which geologic period was the region of Washington State closest to the equator?
At the end of which geologic time period were the continents of South America and Africa joined together and entirely located south of the equator?
(1) Paleogene Period
(2) Jurassic Period
(3) Permian Period
(4) Devonian Period
Ordovician-age crinoid fossils of tropical marine origin are found in the bedrock of the HudsonMohawk lowlands region of New York State. This provides evidence that New York State was once located at a
(1) lower latitude and lower elevation
(2) lower latitude and higher elevation
(3) higher latitude and lower elevation
(4) higher latitude and higher elevation
The map below shows the inferred shape of the North American landmass in the past. The location of Florida is labeled.
Which event was occurring on Earth when Florida was located at the equator?
(1) The dome-like uplift of the Adirondack region began.
(2) The earliest dinosaurs appeared on Earth.
(3) Oceanic oxygen began to enter the atmosphere.
(4) Earth’s first coral reefs were forming.
Labeled lines on the map below show the inferred location of Earth’s equator during the middle of several geologic periods.
Approximately how many million years ago (mya) was the region around current-day Watertown, New York, located the nearest to the equator?
(1) 270 mya
(2) 300 mya
(3) 340 mya
(4) 450 mya
Which block diagram represents the plate motion that causes the earthquakes that occur along the San Andreas Fault in California?
The Hawaiian Islands were formed as a result of
(1) lava flowing over Earth’s surface where two tectonic plates move apart
(2) an oceanic plate moving over a mantle hot spot
(3) two oceanic plates colliding to form an island arc
(4) tectonic plates sliding past each other

Mount Manaro Erupts!
Mount Manaro is a volcano on Ambae Island, about 1400 miles northeast of Australia. Ambae Island is located in the South Pacific Ocean at 15° south latitude, 168° east longitude.
After Mount Manaro had erupted in 1995, Ambae Island residents developed an evacuation plan. When Mount Manaro began erupting gas, steam, and ash on November 27, 2005, scientists and residents watched the volcano carefully.
The eruption became more severe on December 9, 2005, when steam and gases rose 1.8 miles up into the air. Rocks and ash began to fall on nearby farms and homes. Thousands of people left their homes, making it the largest evacuation ever on Ambae Island.
On the diagram in the image provided, draw one arrow through point X and one arrow through point Y to indicate the direction of tectonic plate motion near Mount Manaro. 
Allow 1 credit if both arrows show the correct directions, even if the arrows do not pass through the dots.
