What was the Glomar Challenger’s mission?

Above: The Glomar Challenger was the first research vessel specifically designed in the late 1960s for the purpose of drilling into and taking core samples from the deep ocean floor.

Was Glomar Challenger a successful mission?

Scrapping. After being operated for fifteen years, Glomar Challenger’s active duty was ended during November 1983 and she was later scrapped. Her successor, JOIDES Resolution, was launched during 1985. The ship was a success in collecting rock samples and helped to confirm the Messinian Salinity Crisis theory.

What did Glomar Challenger find? It investigated some 624 sites in the Atlantic, Pacific, and Indian oceans, not only revealing the presence of deep ocean salt domes (which themselves may indicate the presence of oil) but also supporting the theory of plate tectonics by providing evidence of continental drift and seafloor renewal.

What information did the Glomar Challenger study in 1968?

ANSWER: Glomar Challenger studies about the “age of rocks in various places in the ocean” in 1968. EXPLANATION: Glomar Challenger was a “deep sea research vessel” for marine geology and oceanography studies.

What is the purpose of deep sea drilling?

The Deep-Sea Drilling Project (DSDP) was a scientific program for drilling cores of sediment and basaltic crust beneath the deep oceans and recovering them for study. The drilling began in 1968, using the ship Glomar Challenger, and ended in 1983.

What was the Glomar Challenger equipped with?

For 25 years, the Deep Sea Drilling Project (DSDP) operated the Glomar Challenger, a research ship 400 feet (122 meters) in length that was equipped with a drilling platform and scientific laboratories.

Why is the Glomar Challenger a significant contributor to history?

The potential of oil beneath deep ocean salt domes remains an important avenue for commercial development today. But the purpose of the Glomar Challenger was scientific exploration. … The theory of these two geologists attempts to explain the formation of mountain ranges, earthquakes, and deep sea trenches.

When scientists analyzed drilling samples from the Glomar Challenger study which discovery?

When scientists analyzed drilling samples from the Glomar Challenger study, which discovery did they make about rocks in relation to a mid-ocean ridge? Rocks closer to the ridge are newer. Rocks closer to the ridge contain more iron.

What were the results of the Deep Sea Drilling Project?

As for the purpose of the scientific exploration, one of the most important discoveries was made when the crew drilled 17 holes at 10 different locations along an oceanic ridge between South America and Africa. The retrieved core samples provided strong proof for continental drift and seafloor renewal at rift zones.

What is Harry Hess’s theory?

Hess envisaged that oceans grew from their centres, with molten material (basalt) oozing up from the Earth’s mantle along the mid ocean ridges. This created new seafloor which then spread away from the ridge in both directions.

Which event causes the formation of trenches in Earth’s crust quizlet?

Which event causes the formation of trenches in Earth’s crust? lithosphere colliding.

Which is the first step in seafloor spreading process?

1. A long crack in the oceanic crust forms at a mid ocean ridge. 2. Molten material rises and erupts along the ridge.

Which is one piece of evidence of seafloor spreading?

There is lots of evidence that proves that seafloor spreading is occurring. One piece of evidence is mid-ocean ridges. Rocks found near mid-ocean ridges are young and get older as the distance from the ocean ridge increases.

What’s below the ocean floor?

The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

What’s in the ocean floor?

The ocean floor has the same general character as the land areas of the world: mountains, plains, channels, canyons, exposed rocks, and sediment-covered areas. The lack of weathering and erosion in most areas, however, allows geological processes to be seen more clearly on the seafloor than…

Is there drilling in the Mariana Trench?

Fishing, drilling and mining are prohibited in the Marianas Trench National Marine Monument but because of its potential as a source of energy, its sanctuary designation is at risk for recall.
