What is a sensitive device used to detect magnetic fields on the seafloor?
A magnetometer is a sensitive device used to detect magnetic fields on the seafloor. It measures the strength and direction of magnetic fields, which can provide valuable information about the geological structure of the seafloor and help in identifying magnetic anomalies caused by different rock types or mineral deposits.
How is magnetism used to support the theory about seafloor spreading?
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
Used as evidence for sea-floor spreading?
Magnetic striping on the ocean floor is used as evidence for seafloor spreading. As new oceanic crust forms at mid-ocean ridges, Earth's magnetic field is recorded in the rocks in alternating patterns of normal and reversed polarity. This provides support for the idea that new crust is continuously being created at mid-ocean ridges and spreading away in opposite directions.
Sensing device that detects magnetic fields helping confirm seafloor spreading?
A magnetometer is a sensing device that detects magnetic fields and is commonly used to measure magnetic anomalies on the seafloor. By mapping these anomalies, geologists can confirm the process of seafloor spreading by identifying patterns of magnetic stripes that align with known geomagnetic reversals. This data provides valuable evidence for plate tectonics and the movement of Earth's crustal plates.
On a map of the seafloor the boundaries between normally magnetized oceanic crust and reversely magnetized oceanic crust are called?
These boundaries are called magnetic anomalies, where the Earth's magnetic field has shifted relative to the seafloor rocks. These anomalies are used to study the history of plate tectonics and Earth's magnetic field reversals.
What does magnetic?
There are two theories that are used to explain magnetic therapy. One theory maintains that magnets produce a slight electrical current.

How is magnesium used to support the theory of seafloor spreading?
Magnesium is used to support the theory of seafloor spreading because as new oceanic crust forms at mid-ocean ridges, it contains higher levels of magnesium compared to older crust. This can be observed through magnetic anomalies in the oceanic crust, where variations in magnesium content create distinct magnetic stripes that align with the spreading centers. This provides evidence that new crust is being continuously generated at mid-ocean ridges, supporting the process of seafloor spreading.
What tools were used to prove seafloor spreading?
Tools such as sonar mapping, geologic sampling, and paleomagnetism studies were used to provide evidence for seafloor spreading. Sonar mapping allowed for the creation of detailed maps of the ocean floor, revealing features such as mid-ocean ridges and deep-sea trenches. Geologic sampling involved collecting rock samples from the ocean floor to study their age and composition. Paleomagnetism studies focused on analyzing the alignment of magnetic minerals in rocks, providing evidence of past changes in Earth's magnetic field that support the idea of seafloor spreading.
Describe how magnetism is used to support the theory of seafloor spreading?
New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.
When did harry hess propose seafloor spreading?
Harry Hess proposed the idea of seafloor spreading in the early 1960s, with his initial proposal being presented in 1960. This concept revolutionized our understanding of plate tectonics and the movement of the Earth's lithosphere.
