What two types of rock provided evidence of the composition of Earths interior?
Igneous and metamorphic rocks provide evidence of the composition of Earth's interior. Igneous rocks form from the cooling of molten rock (magma), and they can provide information about the chemical composition of the mantle. Metamorphic rocks form from the transformation of existing rocks under high pressure and temperature conditions, offering insights into the conditions present deep within the Earth.
If holes drilled sveral kilometers into earths crust provide direct evidence about earths interior in the form of what?
Rock samples
Geologists learn about Earths interior using indirect evidence from?
Geologists learn about Earth's interior using indirect evidence from seismic waves, magnetic field data, and rock samples from volcanoes and deep drilling. These methods help provide insights into the composition, structure, and properties of Earth's interior layers.
Why do scientist hypothesize use meteorites that hit the earth to provide evidence of composition of earths interior?
The carbonaceous meteorites represent the mantle of the Earth. Pallesite meteorites are composed of iron and olivine which represents the transition between the core and the mantle.
Geologists use direct evidence from learn abut earths interior?
Geologists gather direct evidence about Earth's interior from seismic waves, which are generated by earthquakes and can provide information about the composition and structure of the different layers beneath the surface. They also study rocks brought up from deep within the Earth's crust through volcanic eruptions or mountain building processes to understand the materials present in the interior. By analyzing these direct sources of information, geologists can create models and theories about the Earth's interior composition and processes.
How do you obtain indirect evidence about earths interior?
Seismic waves
How do fossils provide evidence for moving plates?
Their evidence comes from rocks at earths surface.
How do geologists gather evidence about what its like in the earths interior of the earth?
laws of natural
In developing a model of earths deep interior most of the evidence was determined from?
Seismic data
Does indirect evidence of earths interior come from studying rock samples?
Yes, indirect evidence of Earth's interior can come from studying rock samples through techniques like petrology and mineralogy. These studies provide insights into the composition and properties of the deeper layers of the Earth based on the rocks that have been brought to the surface through geological processes.
What changes occur in the composition of the earths interior layer as you move towards the core?
the material is hotter & denser
