Quiz #2 - Formation Of The Hawaiian Islands

The Hawaiian islands are formed by volcanic or basaltic rock. This type of rock is created through volcanic activity, where molten lava cools and solidifies to form solid rock. The Hawaiian islands are located in the middle of the Pacific Ocean and are actually the tops of massive underwater volcanoes. Over millions of years, repeated volcanic eruptions have built up layers of basaltic rock, eventually forming the islands we see today.

When a volcano becomes extinct and magma no longer continues to build its foundation, the island undergoes erosion and sinking. Over time, natural forces such as wind, water, and ice wear away the land, causing it to gradually erode. Without the constant supply of magma, the island loses its stability and can sink lower into the surrounding water. This process is further accelerated by the erosion, as the weakened land is more susceptible to being eroded and washed away by the elements.

The correct answer is "shoals, reefs, and islands". The Hawaiian Islands are known for their diverse topography, which includes not only hills and valleys but also shoals, reefs, and islands. Shoals are shallow areas of water, often found near the coast, while reefs are underwater structures composed of coral or rock. The Hawaiian Islands are also made up of numerous islands, making this answer the most accurate in terms of the geographical features found in the region.

Magma is the correct answer because it is a substance that is known to pour, spout, and ooze out of a vent at the bottom of the ocean on the sea floor. Magma is molten rock that is found beneath the Earth's surface, and when it reaches the surface through volcanic activity, it is called lava. It is responsible for the formation of igneous rocks and plays a crucial role in shaping the Earth's crust.

The Hawaiian islands are unique because scientists have discovered that a hot spot is responsible for creating all the islands in the Hawaiian Archipelago. A hot spot is an area of intense volcanic activity that remains stationary while the tectonic plate moves over it. As the plate moves, new volcanoes form over the hot spot, creating a chain of islands. This explains why the islands get progressively older from east to west, with the youngest island being the Big Island of Hawaii and the oldest being Kauai. The hot spot theory also explains the volcanic activity and the formation of the famous Hawaiian volcanoes, such as Mauna Loa and Kilauea.

Microorganisms that live in a complex family structure are referred to as a colony. A colony is a group of individual microorganisms that work together and live in close proximity to one another, often forming a visible cluster or community. This collective organization allows the microorganisms to function as a unit, sharing resources and coordinating their activities for survival and reproduction.

The East Pacific Rise is a mid-oceanic ridge located in the eastern Pacific Ocean. It is known for its high rate of tectonic activity and is considered one of the fastest-moving tectonic plates on Earth. This ridge marks the boundary between the Pacific Plate and the Nazca Plate, and it is characterized by intense volcanic and seismic activity. The movement of the tectonic plates along the East Pacific Rise results in the creation of new oceanic crust, making it a significant area in terms of plate tectonics.

The earth's crust is broken into 12 ridges. This suggests that there are 12 major tectonic plates that make up the Earth's crust. These plates are constantly moving and interacting with each other, leading to various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. The presence of 12 ridges indicates the complexity and diversity of the Earth's crust, highlighting the dynamic nature of our planet's geology.

Pele is the correct answer because she is a Hawaiian deity associated with volcanoes and is believed to reside on the island of Hawai`i at Kilauea and Mauna Loa. In Hawaiian mythology, Pele is known as the goddess of fire, lightning, wind, and volcanoes, and she is considered to be the creator of the Hawaiian Islands. She is often depicted as a powerful and fiery goddess who shapes the land through her volcanic activity. Therefore, it is believed that Pele lives on the island of Hawai`i at Kilauea and Mauna Loa.

Polyps are a type of microorganism that build the largest structures in the world. They are responsible for creating coral reefs, which are massive structures that provide habitats for various marine life. These structures are formed over long periods of time as polyps secrete calcium carbonate to create their exoskeletons. As more and more polyps accumulate, the coral reef grows larger and becomes a vital part of the marine ecosystem. Therefore, polyps are the correct answer as they are known for building the largest structures in the world.

The correct answer is Ko`olau and Waianae. These two volcanoes are responsible for the formation of the island of O`ahu. The Ko`olau volcano is located on the eastern side of the island, while the Waianae volcano is on the western side. Together, their volcanic activity over millions of years created the landmass of O`ahu.

The answer is a list of the eight major Hawaiian islands: Hawai`i, Maui, Kaho`olawe, Lana`i, O`ahu, Moloka`i, Kaua`i, and Ni`ihau.
