What is the most important source of information about the interior of the earth?
SEISMIC WAVES Seismic activity SEISMIC WAVES Seismic activity is one of the most important sources of information about the interior of the earth. Earth quakes generate different types of waves. The characteristics of the waves suggest properties of different layers of the earth.
Which gives the most reliable information about the earth internal structure?
Seismic waves They are the most important source available to understand the layered structure of the earth. The velocity of seismic waves changes as they travel through materials with different elasticity and density.
Which of the following sources gives information of Earth’s interior indirectly?
Seismic waves, gravitational field, magnetic field, falling meteors etc. are examples of indirect sources. They are very important for knowing about the earth's interior.
What are the direct sources of information about the interior of the earth Class 11?
Answer: Rocks obtained from mining areas and materials obtained from volcanic eruption are the direct sources of information about the interior of the earth.
Which one of the following has provided the most information about the core of the earth?
Most core research has been conducted by measuring seismic waves, the shock waves released by earthquakes at or near the surface. The velocity and frequency of seismic body waves changes with pressure, temperature, and rock composition.
Which gives the most reliable information about the earth’s internal structure?
Seismic waves They are the most important source available to understand the layered structure of the earth. The velocity of seismic waves changes as they travel through materials with different elasticity and density.
Which one of the following is a direct source of the information about the interior of the earth earthquake waves volcanoes gravitational force Earth magnetism?
The correct answer is Volcanic eruption. Volcanic eruptions are direct sources of information about the interior of the earth.
What has provided the most information about the structure of Earth’s core mantle and lower crust?
Most core research has been conducted by measuring seismic waves, the shock waves released by earthquakes at or near the surface. The velocity and frequency of seismic body waves changes with pressure, temperature, and rock composition.
How do scientists know about the layers of the Earth?
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.
What is the most important part of the earth’s internal structure?
The core is the centre of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron and molten rock….The core.

Which one of following is direct source of the information about interior of Earth by Brainly?
Answer: Rocks obtained from mining areas and materials obtained from volcanic eruption are the direct sources of information about the interior of the earth.
What has been the most useful method for determining the structure of the Earth’s interior?
Of course, seismic techniques have been most widely applied to the detection and study of earthquakes, but there are many other applications, and arguably seismic waves provide the most important information that we have concerning Earth's interior.
In which science do the study of the interior of the Earth?
The study of seismic waves is known as seismology. Seismologists use seismic waves to learn about earthquakes and also to learn about the Earth's interior. One ingenious way scientists learn about Earth's interior is by looking at earthquake waves.
Which gives the most reliable information about the Earth internal structure?
Seismic waves They are the most important source available to understand the layered structure of the earth. The velocity of seismic waves changes as they travel through materials with different elasticity and density.
What is the internal structure of the earth?
The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.
How earthquake waves provide information about the interior of the Earth?
Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth. As seismic waves pass through the Earth, they are refracted, or bent, like rays of light bend when they pass through a glass prism.
What type of evidence is primarily used to study the interior of the Earth?
Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from seismic waves.
How do geologists know about the inside of the Earth quizlet?
Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from seismic waves.
Which is the most useful method for determining the structure of the interior of the Earth?

How do scientists know about Earth’s interior and all of its layers quizlet?
Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from seismic waves. the crust, the mantle, and the core. These layers vary greatly in size, composition, temperature and pressure.
Which of these provide evidence for the structure of the Earth’s interior?
Evidence on the structure and composition of the earth's interior comes from (1) observations of surface rocks, (2) geophysical data from earthquakes, flow of heat from the interior, the magnetic field, and gravity, (3) laboratory ex- periments on surface rocks and minerals, and (4) compari- son of the earth with other …

How do we know the Earth’s layers?
Our modern, scientific understanding of the Earth's interior structure is based on inferences made with the help of seismic monitoring. In essence, this involves measuring sound waves generated by earthquakes, and examining how passing through the different layers of the Earth causes them to slow down.
