Where would you drill to recover Jurassic age samples of the oldest basalts of the oceanic crust?
oceanic side of the Aleutian trench
What are three kinds of evidence scientists have found to support ocean floor spreading?
1. Paleomagnetism. 2.(Thickness of the beds) Samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge. 2. (Age of the sea-floor) The rock making up the ocean floor is considerably younger than the continents, with no samples found over 200 million years old, as contrasted with maximum ages of over 3 billion years for the continental rocks. This confirms that older ocean crust has been reabsorbed in ocean trench systems. 3. (Geologic Activities) Study of the fracture zones that offset the sections of the ridge.
What is the boiling point range of the known samples?
WHAT SAMPLES???
What are cylindrical samples of ocean sediment?
also called core samples. reason is that they drill into the material with a hollow drill removing the core for analysys.
What are two types of evidence geologists use to learn about Earths interior?
Rock samples and Indirect evidence from seismic waves Direct evidence from rocks samples and indirect samples from seismic waves my science teacher told me

Where do scientists get rock samples to discover earth's interior?
They recover rock samples from volcanic eruptions.
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.

Could you get DNA samples off of a saber-toothed tiger bone?
Yeah, but you couldn't go Jurassic park and clone one
A volcano has steep sides rock samples from the immediate area contain both basaltic and granitic rock samples Excavation of the area reveals alternating layers of ash and lava flows what type?
Composite cone The hallmark of a composite cone composition is the mixture of cinder cone characteristics (granitic debris, very steep cone profile, and explosive eruptions) with shield cone characteristics (large footprint with gently sloping sides, basaltic debris, and lava flows).
What were things to do during the Jurassic period?
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,
What made the scientists believe that the sea floor is spreading?
1. What made scientist believe that the seafloor was spreading? Samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge. Also, the rock making up the ocean floor is considerably younger than the continents, with no samples found over 200 million years old, as contrasted with maximum ages of over 3 billion years for the continental rocks.

How do core samples along the ocean floor help to explain tectonic movement?
Core samples would reveal that the further from the mid-ocean ridge you go, the greater the overlying sediment on top of the basaltic crust. This would indicate that the crust closer to the ridge was younger and more recently formed. The creation of new crust at mic-ocean ridges is the crucial evidence for the movement of tectonic plates.
Do i say can i have samples about them or samples of them?
samples of them
What is Discrete time signal processing?
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.
