What else can I help you with?
What is a weak spot in the Earths crust where molten rock comes to the surface?
The mid-Atlantic ridge.
If you could collect a sample of rock from the Mid-Atlantic Ridge where would you look to find the youngest rocks?
You would want to look for rocks at the center of the Mid-Atlantic Ridge, where new oceanic crust is forming through seafloor spreading. The rocks found closest to the ridge axis are typically the youngest, as they have most recently solidified from magma.
Would you expect a rock sample found 1500 km from the mid Atlantic ridge to be younger or older than 90 million years?
A rock sample found 1500 km from the Mid-Atlantic Ridge would generally be expected to be older than 90 million years. As tectonic plates move apart at the ridge, new oceanic crust is formed, which ages as it moves away from the ridge. Given the age of the oceanic crust is typically younger near the ridge and increases with distance, a sample that far away would likely be significantly older than 90 million years.
Why is the Mid Atlantic ridge younger than the rock found on the edge of the continents?
The Mid-Atlantic Ridge is younger because it is where new oceanic crust is continuously being formed through seafloor spreading, pushing the older crust away from the ridge. In contrast, the rocks found on the edge of continents are older because they have been subjected to longer periods of erosion and tectonic activity.
What mountains were formed by a divergent boundary?
The Mid-Atlantic Ridge and the East African Rift are two examples of mountain ranges formed by divergent boundaries. The movement of tectonic plates away from each other at these boundaries causes molten rock to rise to the surface, creating new crust and pushing the existing crust upwards to form mountains.
Is the mid Atlantic rock the oldest rock?
The Mid-Atlantic Ridge is neither Continental rock or indeed the oldest rock on the planet. The rock in the ridge is commonly the youngest, or of the youngest, on the planet, as it was formed most recently, and is oceanic, not continental, crustal rock.
Where are the youngest rock on the ocean floor found?
Near the mid-Atlantic ridge.
Why the rock of the mid Atlantic ridge is younger than the rock found on the edge of the continents?
The rock of the Mid-Atlantic Ridge is younger because it is formed through seafloor spreading where new crust is created at the ridge and moves away from it. In contrast, the rock found on the edge of continents is older because it has been at the surface for a longer time and has undergone various geological processes.
What does mid-ocean ridge do?
makes new rock
What is a weak spot in the Earths crust where molten rock comes to the surface?
The mid-Atlantic ridge.
Why is the Atlantic ocean expanded?
The Atlantic Ocean has the mid-ocean ridge which has lava flow about every year and pushes out the rock around it. The Atlantic ocean expands about two inches every year pushing the continent with it.
How can rock that is formed at the mid Atlantic ridge be changed into sedimentary rock?
Rock formed at the mid-Atlantic ridge can be uplifted through tectonic processes and exposed to weathering and erosion. The eroded rock particles can then be transported by rivers or wind and eventually deposited in a basin, where they can accumulate over time to form sedimentary layers. Through compaction and cementation, these layers can then lithify into sedimentary rock.
How old are the oldest rock of the Atlantic sea floor?
The Mid-Atlantic Ridge is part of the greater mid-ocean ridge system, an underwater mountain range that is over 40,000 miles long. The age of new rock closest to the ridge would be roughly the same anywhere along the ridge.
Where are the youngest rocks in the Atlantic ocean?
The youngest rocks in the Atlantic Ocean are found along the mid-ocean ridge system, where new oceanic crust is formed through volcanic activity. This process, known as seafloor spreading, occurs along underwater mountain ranges, such as the Mid-Atlantic Ridge. As molten rock cools and solidifies at the ridge, it creates new oceanic crust, making this region home to some of the youngest rocks in the Atlantic.
When was Rock Ridge Music created?
Rock Ridge Music was created in 2004.
