Where might geologists find oil deposits 200 million years?

Oil deposits approximately 200 million years old have been discovered in Brazil.

What features did geologists and scientists discover in the ocean that puzzled them?

These two topographic features of the ocean floor—deep-sea trenches and ocean ridges—puzzled geologists for over a decade after their discovery.

How do ancient glacial deposits in Africa India Australia and South America support the idea of continental drift?

how do ancient glacial deposits in Africa, India, Australian and south america support the idea of continental drift. the scientific community strongly believed that the continents and ocean basins were permanent, fixed features of earths surface. relationship among mantle convection, ocean ridges, and subduction zone.

How do ocean ridges and deep sea trenches support the theory of sea floor spreading?

How do ocean ridges and deep-sea trenches support the theory of seafloor spreading? THE THEORY OF SEAFLOOR SPREADING STATES THAT OCEAN RIDGES ARE PLACES WHERE NEW OCEAN CRUST IS FORMED; TRENCHES ARE PLACES WHERE IT IS DESTROYED. THESE DATA ARE CONSISTENT WITH NEW CRUST FROMING AT RIDGES AND BEING DESTROYED AT TRENCHES.

Why is the oldest oceanic lithosphere only 200 million years old?

Most oceanic crust is less than 200 million years old, because it is typically recycled back into the Earth’s mantle at subduction zones (where two tectonic plates collide).

Why is it that the Pacific Ocean floor is no older than about 200 million years and yet the continents are much older?

Why are there no oceanic rocks older than 200 million years? Oceanic crust is eventually destroyed in subduction zones. Although oceanic crust has been forming on Earth for over 4 billion years, all of the sea floor older than about 200 million years has been recycled by plate tectonics.

Why are glacial deposits found in Africa?

Glaciers were found in Africa because continents were connected and party covered with snow near the south pole long ago.

What is the name of the plant fossil found in South America India Australia and Antarctica that proved these continents were derived from a single continent?

Glossopteris
Reaching as tall as 30 meters, the Glossopteris emerged during the early Permian period (299 million years ago) and became the dominant land plant species until the end of the Permian. The Glossopteris fossil is found in Australia, Antarctica, India, South Africa, and South America—all the southern continents.

What geological feature was discovered by Harry Hess and his team in the oceanic crust?

Mid Ocean Ridges
Hess discovered that the oceans were shallower in the middle and identified the presence of Mid Ocean Ridges, raised above the surrounding generally flat sea floor (abyssal plain) by as much as 1.5 km.
