A coastal town is experiencing significant shoreline erosion due to strong ocean waves. To protect both the beach and a nearby road that runs along the coast, engineers decided to build a solid structure that runs parallel to the shoreline. This structure is designed to absorb and reflect wave energy to prevent further erosion. What is this type of structure called?_______________.

Mount Rainier in Washington State hasn't erupted in over 500 years, yet scientists still consider it one of the most dangerous volcanoes in the Cascade Range. This is due to several factors, including frequent nearby earthquakes, an active hydrothermal system, its great height, and its thick glacier cover. Because it hasn’t erupted in centuries but still shows signs of activity, how would this volcano be classified?

March 1886, in Rome, Georgia, rain began falling and continued for many days. The rainfall caused the Oostanaula and Coosa rivers to swell to 40.3 feet, the highest level ever recorded. Downtown Broad Street was 10 feet underwater. The city was drowning. As a result of this flooding, city officials determined that a __________ needed to be built to help prevent flooding of this magnitude from ever happening again. The structure still helps control flooding to this day.

Engineers in northern regions often inspect roads more closely in early spring than at other times of the year. They frequently find that cracks and potholes have become significantly worse since the previous fall. This increase in road damage is linked to repeated cycles of water entering pavement cracks, freezing, expanding, and eventually breaking the surface apart. Which scenario best illustrates this type of mechanical weathering known as ice wedging?

Two students in Rome, Georgia are discussing whether a volcano could form in their backyard.
Jordan’s claim:
“A volcano could form here because magma can push through the Earth’s crust anywhere if the pressure builds up enough.”
Taylor’s claim:
“A volcano is unlikely here because Rome, Georgia is far from tectonic plate boundaries and hot spots, and it’s on the Atlantic side—far from the Ring of Fire where most volcanoes occur.”
Which student’s claim is scientifically correct, and why?
