Where would you drill to recover samples of the oldest basaltic oceanic crust which is Jurassic age?
To recover samples of the oldest basaltic oceanic crust, which is Jurassic in age, you would need to drill in regions where the crust is still preserved. The best places to do this would be in certain portions of the western Pacific Ocean, such as the western Pacific Basin or the western regions of the Northwest Pacific Ocean, where Jurassic-aged oceanic crust is known to exist. Conducting deep-sea drilling operations in these areas can help recover samples for study.
What is the oldest part of earth's crust?
The Nuvvuagittuq greenstone belt is the oldest part of earth's crust. Dating back 4.28 billion years old (the earth is estimated to be 4.6 billion years old), it is the only piece of land still known to exist pre-Archean era.
Where are the oldest oceanic floors in the world?
The oldest in-situ oceanic lithosphere is found at lithospheric subduction zones, where oceanic crust is being drawn into the mantle. These would normally be the point furthest away from its point of origin at the mid-ocean ridge.However the oldest remnant of oceanic crust found on earth dates from the early Archean when the lithosphere began to develop and are a product of obduction (where slivers of oceanic crust are thrust onto a continental crustal plate rather than below them). An example would be the Jamestown Ophiolite Complex of the Barberton greenstone belt in South Africa which formed approximately 3.5 billion years ago.
What Is the relation between age of oceanic crust and distance from divergent plate boundary?
When oceanic crust is still young, it's relatively warm. The older it gets, the colder it gets. The colder it gets, the less volume it takes in, however, it's still the same amount of matter. This causes a bigger density, thus causing the crust to sink deeper into the mantle.
What thin layer of rock surrounds the earth?
That's called the crust. The size of the crust compared to the size of the Earth's mantle can be compared to the size of the radius of an apple as the mantle and the apple's skin as the thickness of the crust. the crust is broken up into several plates that float and move around on the mantle's molten surface.
What part of the Pacific Ocean is the oldest?
The oldest part of the Pacific Ocean is the western part near the Mariana Trench, particularly the ocean floor around the Mariana Islands. This region features some of the oldest oceanic crust, dating back to approximately 180 million years ago. The process of subduction in this area has contributed to the recycling of crust, but remnants of ancient crust can still be found.

Where is the oldest windmill now?
The oldest windmill still standing is likely the Chesterton Windmill in Warwickshire, England, believed to have been built in the 1630s. It is a well-preserved example of a stone tower mill and is still operational, though it is now primarily a tourist attraction.

Why are the oldest rocks found on earth younger than the oldest lunar rocks that Apollo brought back from the moon?
The Earth is still tectonically active and because Earth has weather. The tectonic activity refreshes the crust as some plates are forced under others, removing old rock from the surface, and things like the sea floor spreading and volcanic activity producing all new crust. Additionally, the weather on the Earth constantly works to erode existing crust and wash it into the oceans.The moon is neither terctonically active nor is there weather. The moon is, in planetary science terms, dead. There is no process to remove old surface rocks and replace with new ones.
