What are the three lines of evidence for Plate Tectonics?
The three lines of evidence for Plate Tectonics are: 1) the distribution of earthquakes and volcanoes along plate boundaries, 2) the matching shapes of continents on opposite sides of the Atlantic Ocean, known as continental drift, and 3) the patterns of magnetic striping on the ocean floor that provide evidence of seafloor spreading.
New crust forms on the ocean floor due to what process?
New crust forms on the ocean floor through seafloor spreading, where magma rises up from the mantle through mid-ocean ridges and solidifies into new crust as tectonic plates move apart.
The topography of the ocean floor?
The ocean floor topography includes features like mid-ocean ridges, trenches, abyssal plains, seamounts, and continental shelves. These features are shaped by processes such as plate tectonics, volcanic activity, and erosion. Mapping the ocean floor is crucial for understanding marine ecosystems, climate patterns, and natural hazards.
What technological methods used to prove that plate tectonics occur?
Technological methods used to prove plate tectonics include GPS to measure crustal movement, seafloor mapping to show oceanic spreading, satellite imagery to monitor surface changes, and seismic tomography to visualize Earth's interior structures. These methods provide evidence for plate motion and interactions, supporting the theory of plate tectonics.
What two topographic features of the ocean floor were discovered only with the use of sonar?
Two topographic features of the ocean floor discovered with sonar are underwater mountain ranges known as mid-ocean ridges and deep ocean trenches. Sonar technology allowed scientists to map these submarine structures and gain insights into plate tectonics and the Earth's geology.
What happen to plate tectonics as they move?
what material forms new pieces of ocean floor
How do plate tectonics affect the ocean floor?
They change its size and shape.
What is responsible for the formation of ocean-floor features?
Plate tectonics and (river) erosion are responsible for the formation of ocean-floor features.
What is responsible for the formation of ocean floor features?
Plate tectonics and (river) erosion are responsible for the formation of ocean-floor features.
Why isn't the ocean floor a flat surface?
Plate Tectonics, to put it simply.
How did the ocean floor help develop the theory pf plate tectonics?
*of, sorry
What are some features of the ocean floor that provide evidence for plate tectonics?
they found fossils
What causes material to form at a mid-ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
What cause new material to form at a mid ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
What was Marie Tharp's contribution to plate tectonics?
Marie Tharp's contribution to plate tectonics was the creation of the first scientific map of the ocean floor that revealed the existence of a mid-ocean ridge and deep-sea trenches. Her mapping work provided critical evidence in support of the theory of continental drift and plate tectonics.
How does an earthqake happen?
plate tectonics
How do the features of the ocean floor help support the theory of plate tectonics?
The features of the ocean floor, such as mid-ocean ridges, deep-sea trenches, and underwater volcanoes, provide evidence for the theory of plate tectonics. These features are formed by processes like seafloor spreading, subduction, and volcanic activity, which are central to the movement of Earth's tectonic plates. Additionally, the magnetic striping pattern on the ocean floor supports the idea of seafloor spreading and plate movement over time.
