What type of plate boundary is Mauna Kea on?
What type of plate boundary is Mauna Kea on?
convergent tectonic boundary
Unlike the hot spot that formed Mauna Kea, Mount Everest formed as the result of a convergent tectonic boundary. As two continental plates came together, the crust buckled and pushed upward, creating the Himalayan mountain range.
What are contour lines examples?
In cartography, a contour line (often just called a “contour”) joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
What is Mauna Kea an example of?
Mauna Kea is one of five volcanoes that form the island of Hawaiʻi, the largest and youngest island of the Hawaiian–Emperor seamount chain. Of these five hotspot volcanoes, Mauna Kea is the fourth oldest and fourth most active.
What is the topography of Mauna Loa?
It is an active shield volcano with relatively gentle slopes, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 125 feet (38 m) lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and they tend to be non-explosive.
How many times did Mauna Kea erupt?
Between 1912 and 2012, there were nearly 50 Kīlauea eruptions, 12 Mauna Loa eruptions, and one Hualālai intrusion of magma. Mauna Kea most recently erupted only about 4,000 years ago. Lō’ihi, the submarine volcano located off the south coast of Kīlauea, erupted twice between 1950 and 1996.
What is the contour interval of Mauna Kea?
The Island of Hawai`i, including Mauna Kea, in a map showing the distance from the ground surface to the modeled upper surface of dense volcanic cores. Near the center of the island, the edifice of Mauna Kea appears covered with alkali basalt vents (gray diamonds). The contour interval represents 1 km.
Is there a crater on the summit of Mauna Kea?
The symmetrical Goodrich cinder cone has a well-preserved crater. It is one of many late-stage cinder cones capping the summit of Mauna Kea, and is seen here from the the summit of Mauna Kea with Mauna Loa volcano to its NE. Dark-colored, unvegetated lava flows, many of historical age, descend the flanks of Mauna Loa.
Which is higher Mauna Loa or Mauna Kea?
Tall cinder cones atop the summit of Mauna Kea and lava flows that underlie its steep upper flanks have built the volcano a scant 35 m (115 ft) higher than nearby Mauna Loa.
Where are the cinder cones located on Mauna Kea?
(Main Map) Holocene cinder cones and lava flows are located on Mauna Kea’s lower S flank, the lower extent of which have been covered by Mauna Loa lava flows. The two sets of isopachs indicate tephra units vented from the cinder cones Pu`ukole and Pu`u Loa Loa.
