How can scientists lean about the mantle if they cannot study it directly?
Scientists study the mantle indirectly by analyzing seismic waves from earthquakes, studying volcanic eruptions, and examining rock samples brought to the surface by volcanic activity. By combining these methods, scientists can gain valuable insights into the composition, temperature, and behavior of the Earth's mantle.
Why do scientists look to the ocean floor to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.
How is the composition and structure of the Earth determined?
The composition and structure of the Earth are determined through various methods, including seismic studies, rock samples, and geophysical surveys. Scientists use these techniques to analyze the Earth's layers, such as the crust, mantle, and core, and understand the distribution of different materials and structures within the planet.
How have scientists determined What is inside the Earth?
Scientists have used seismic waves from earthquakes to study the Earth's interior. By analyzing how these waves travel through the Earth, scientists have been able to determine the density and composition of different layers like the crust, mantle, and core. Additionally, studies of meteorites and laboratory experiments have provided further insights into the Earth's composition.
How can scientists learn about the mantle if we can't directly observe it?
Scientists study the mantle by analyzing seismic waves and volcanic activity. By measuring the speed and direction of seismic waves as they travel through the mantle, researchers can infer properties like temperature and composition. They also study the rocks and minerals brought up by volcanoes to gain insights into the composition and behavior of the mantle.
How have scientists determined the composition of the earths mantle?
by studying seismic wave travel times, scientist have determined that the lithosphere, which includes the crust and the top of the upper mantle is made up primaraly of the ingenueos rocks granite, basalt and peridotite
Where is earths greatest bulk composition?
mantle
What is earths upper mantle composition?
hard rock
What are ways the scientists can learn about the earths mantle?
seismometers

By combining these methods, scientists can gain valuable insights into the composition, temperature, and behavior of the Earth's mantle.
How can scientists infer the consistency of the earths mantle?
They can do this by how and how quickly seismic waves can move through the mantle.
Which structural layer of earths interior have scientists concluded is liquid?
the mantle

What is the composition earths mantle?
The mantle is 82% of Earth's volume. It is composed of ultramafic rock called peridotite, which is hot enough to flow.
