Scientists have measured and compared the areas of the glaciers in the park since the late 1800s. This table shows the changing area of Sperry Glacier in the park since 1840.

Year | Area in square km
1840 | 3.75
1920 | 3.30
1940 | 1.5
2005 | 0.80

Area of Sperry Glacier

Which year did Sperry Glacier have the smallest area according to the table above?

• 1840

• 1920

• 1940

• 2005

How do Earth’s spheres interact when a glacier moves across its surface? Name three spheres and give examples of interactions.

• The cryosphere (glacier) scrapes the geosphere (rocks), melts into the hydrosphere (water), and affects the atmosphere (air temperature).

• The biosphere (plants) grows on the glacier, the hydrosphere (water) freezes, and the geosphere (rocks) melts.

• The atmosphere (air) turns into rocks, the hydrosphere (water) becomes soil, and the biosphere (plants) freezes.

• The geosphere (rocks) floats on the hydrosphere (water), and the cryosphere (glacier) evaporates.

Emily mixes cornstarch with water on top of pebbles in a pan to build a model of a glacier. She places the pan on a textbook at a tilt. Next, she observes as the glacier with pebbles moves slowly and deposits till at the bottom of the pan. What does the glacial till form at the bottom of the pan?

• horn

• arete

• cirque

• moraine

The beach is a place where a lot of erosion happens. Waves and wind are constantly moving sand from place to place. Which of these landforms could protect communities living near beaches during a hurricane that caused big waves to hit the coast?

• sea arch

• barrier island

• sea stack

• sea cave

Define the term: barrier islands.

• Barrier islands are long, narrow offshore deposits of sand or sediment that run parallel to the coastline and protect the shore from the effects of waves and storms.

• Barrier islands are large inland mountains formed by tectonic activity.

• Barrier islands are underwater volcanoes that occasionally erupt and form new land.

• Barrier islands are deep ocean trenches located far from any coastline.

Define the term: longshore drift.

• Longshore drift is the movement of sand and sediment along the shoreline caused by waves hitting the coast at an angle.

• Longshore drift is the process of wind eroding rocks on a mountain.

• Longshore drift is the vertical movement of water in the ocean due to temperature differences.

• Longshore drift is the movement of tectonic plates beneath the Earth's surface.

Define the term: sea arch.

• A sea arch is a natural rock formation where an arch has formed with an opening underneath, usually created by wave erosion.

• A sea arch is a man-made bridge built over the ocean for transportation.

• A sea arch is a type of coral reef found only in tropical waters.

• A sea arch is a deep underwater trench formed by tectonic activity.

Define the term: sea stacks.

• Sea stacks are vertical columns of rock that have been isolated from the mainland by the erosive action of waves.

• Sea stacks are underwater volcanoes that erupt periodically.

• Sea stacks are large sand dunes formed by wind action along the coast.

• Sea stacks are coral reefs found only in tropical waters.
