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.
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 is it difficult to be precise about the composition of the earths early atmosphere?
It is challenging to be precise about the composition of Earth's early atmosphere because there is limited direct evidence available from that time period. The composition of ancient atmospheres is inferred from indirect sources like ancient rocks, minerals, and fossilized remains, which can give us clues but not a complete picture. Additionally, the Earth has undergone significant changes over billions of years, further complicating efforts to accurately reconstruct the exact composition of the early atmosphere.
Why do you think scientists study earths interior?
Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.
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.
What collide with earth provide evidence of earths inner composition?
WikiAnswers doesn't do "fill in the blank" statements very well. Please rephrase this, as Alex Trebeck says, in the FORM of a question.

What two types of rock provided evidence of the composition of Earth'sinterior
How does the surface of the earth change when two continental plates collide?
The Earths surface changes shape when plates collide when the earths surface overlaps or when there are Earthquakes.
Movement along the earths surface caused by an earthquake?
Collide
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
What provides geologist with evidence of earths past including geologic events and life forms?
The rocks of Earth's crust, especially sedimentary rocks
How do foothills change over time?
When earths plates collide together
How do fossils provide evidence for moving plates?
Their evidence comes from rocks at earths surface.
