oceanic side of the Aleutian trench
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.
Pieces of evidence for sea floor spreading include the presence of mid-ocean ridges where new crust is formed, symmetric magnetic striping on either side of mid-ocean ridges, age dating of oceanic crust that shows it gets older as it moves away from ridges, and the discovery of pillow basalts and other volcanic rocks on the ocean floor.
The first step in comparing soil samples is to collect representative samples from each location. Ensure that samples are taken consistently and are handled carefully to maintain their integrity for accurate comparison.
Other than abundant matching fossils and sedimentary rock on opposite sides of the Atlantic Ocean and the apparent puzzle piece appearance of the continents on either side of the Atlantic, there is the presence of the mid-oceanic ridges, areas where new oceanic crust is created. The magnetic orientation of the basaltic oceanic crust as it forms is the mirror image of the magnetic orientation of the basaltic oceanic crust on the other side of the ridge, indicating that the seafloor is spreading in both directions away from ridge. Additionally, the dating of rock on the ocean floor has shown that oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached.And finally, accurate measurements have been made by global positioning devices which verify that seafloor spreading is occurring.
Scientists prove seafloor spreading through various methods, including mapping of magnetic stripes on the ocean floor, analysis of seismic activity, and examination of rock samples collected from the ocean crust. These techniques provide evidence of tectonic plate movement and the creation of new oceanic crust at mid-ocean ridges.

Yes
They recover rock samples from volcanic eruptions.
the Moon has experienced volcanic activity in the past. Vesicular basalts contain cavities that suggest the presence of gases when the lava solidified, indicating volcanic eruptions on the Moon. This provides evidence of a dynamic geological history on the Moon.
Yeah, but you couldn't go Jurassic park and clone one

Rock samples of the ocean floor can be acquired through various methods such as deep-sea drilling or collecting samples using submersibles or remotely operated vehicles. Scientists also study samples brought up during underwater volcanic eruptions or through natural processes like landslides and fault movements. These samples provide valuable insights into the composition and history of the oceanic crust.
If you were lucky enough to get to visit the Jurassic, you'd want to locate and photograph as many prehistoric animals, including dinosaurs, as possible. You'd also want to make detailed observations regarding their behavior and diet. If you could get DNA samples, they would also be a huge advantage to the scientific community,
In "Jurassic Park: Operation Genesis," you can clone dinosaurs by using the DNA samples you collect. First, ensure you have a functioning DNA lab and enough power. Then, access the lab, select a dinosaur species, and use the acquired DNA to create the clone. Once the cloning process is complete, you can release the dinosaur into your park.

While processing a signal through a channel, it is preferred to sample it. It is because of the following reasonsAs we send only the samples, the gap between samples can be used to send another signal.Multiplexing is possibleSamples occupy less space than signalsTotal signal may not be required to recover dataAnd hence we use samples which are nothing but discrete time signals. hence, it is called discrete time signal processing.
