Hawaiian
Islands Ashirvad Varma Parth Jain Abhijay Kumar Mauna Loa Basic Info Did you know... Mauna Loa is the largest volcano on Earth in terms of volume and area covered! and guess what else! It's still ACTIVE!!! Where exactly is Mauna Loa? Mauna Loa is in the United States. More specifically, it's near Hilo, Hawaii. Mauna Loa is in North America. The actual islands of Hawaii are located on the Pacific Plate, but are formed by a hot spot. Mauna Loa By: Mrs. Crupi's Favorite Students Plate Tectonics What plates caused Mauna Loa to form? TRICK QUESTION! Mauna Loa is formed by a hot spot, and so are the rest of the Hawaiian Islands. What's a hot spot? A hot spot is a stationary opening where magma from the mantle flows upward to the surface. While the plates move, (for Hawaii it would be the Pacific Plate), the hot spot would form new landmasses or islands/archipelagos. Type of Volcano What shape/cone and what kind of magma does Mauna Loa have? Mauna Loa is a Shield Volcano and it has basaltic magma. What type of eruption does it produce: violent, quiet or both? It's QUIET!! What kind of rock fragments come out of this volcano? Mauna Loa produces sedimentary and metamorphic rocks! Effects The closest city to Mauna Loa is Hilo, which has 170,000 people! One legend is about the fire goddess, Pele, who was driven out by her sister, Namakaokahai. Pele decided to make her home on the slopes of Mauna Loa. Mauna Loa has erupted 39 times since 1843. It erupts on average every 6 years. Its most recent eruption was in 1984. The only real danger is lava because it blocks out streets. In fact, $2.3 billion has been invested for new construction, as a result of lava flows. Global Affects How does Mauna Loa's eruptions affect global temperature? Not a significant amount of increase because Mauna Loa does not erupt so frequently. What economic effect does this pose globally? Because communities surrounding Mauna Loa lost interest in investing money towards construction etc, the economy has slowed down since 2008. What are some benefits? Some benefits include business opportunities, tourism, and a boom in agriculture, due to the rich volcanic soil. Bibliography Here are our four sources! Wikipedia. "Mauna Loa." Wikipedia.

Is this a realistic photo of Mauna Loa? Yes, because it is easy to see that this lava is flowing smoothly. Mauna Loa has basaltic magma, so this is a correct picture. No, because of the violent eruption, this magma is rhyolitic, not the type of magma found in Mauna Loa. What kind of volcano is Mauna Loa? TRICK QUESTION!!!

ITS A SHIELD VOLCANO!!! A) Composite
B) Cinder cone What island is the Mauna Loa on? ITS ON THE MAIN ISLAND! On average, how often does Mauna Loa erupt? Mauna Loa is closest to what city? HILO, HAWAII On average, Mauna Loa erupts every 6 years. BONUS QUESTION! Warm-up Question How was Mauna Loa formed? By a hot spot and the Pacific plate.
