Questions and Answers
- 1.
The Hawaiian Islands consist of many __________________
- A.
Hills, valleys and pot holes
- B.
Shoals, reefs, and islands
- C.
Sand, rivers, lakes, and lagoons
- D.
Atolls, parks, and ditches
Correct Answer
B. Shoals, reefs, and islandsExplanation
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.Rate this question:

The earth's crust is broken into ________ ridges
- A.
10
- B.
18
- C.
12
- D.
6
Correct Answer
C. 12Explanation
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.Rate this question:

The Hawaiian islands are considered to be huge ___________________ mountains in the middle of the pacific ocean.
- A.
Coral rock
- B.
Limestone rock
- C.
Volcanic or basaltic rock
- D.
Continental or granite rock
Correct Answer
C. Volcanic or basaltic rockExplanation
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.Rate this question:

This substance known as liquid rock pours, spouts and oozes out of a vent at the bottom of the ocean on the sea floor.
- A.
Sand
- B.
Moist crustal crumbs
- C.
Limestone
- D.
Magma
Correct Answer
D. MagmaExplanation
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.Rate this question:

This is one of the fastest moving tectonic plates on earth.
- A.
West North West Pacific Subduction
- B.
South Atlantic Dip
- C.
East Pacific Rise
- D.
Asia Pacific Submergence
Correct Answer
C. East Pacific RiseExplanation
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.Rate this question:

The Hawaiian islands are unique because scientist have discovered that a ____________ is responsibile for creating all the islands in the Hawaiian Archipelago.
- A.
Plate
- B.
Chain
- C.
Hot spot
- D.
Coral reef
Correct Answer
C. Hot spotExplanation
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.Rate this question:

The two main volcanoes that formed the island of O`ahu are?
Correct Answer
Ko`olau
Waianae
koolau
waianaeExplanation
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.Rate this question:

Who lives on the island of Hawai`i at Kilauea and Mauna Loa?
- A.
Pele
- B.
Kane
- C.
Shiva
- D.
Kanaloa
Correct Answer
A. PeleExplanation
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.Rate this question:

These are the micro oganisms that build the largest structures in the world.
- A.
Crayfish
- B.
Polyp
- C.
Plankton
- D.
Panda
Correct Answer
B. PolypExplanation
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.Rate this question:

These micro organism lives in a complex family structure, what is this unit called.
- A.
`ohana
- B.
Colony
- C.
Clutch
- D.
Batch
Correct Answer
B. ColonyExplanation
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.Rate this question:

When a volcano becomes extinct and magma no longer continues to build it's foundation, what happens to the island?
- A.
Lean and fall
- B.
Tilt and melt
- C.
Slip and drift
- D.
Erosion and sinking
Correct Answer
D. Erosion and sinkingExplanation
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.Rate this question:
