The inside of the Earth consists of coat disrobe and core. The earth’s coat is wetting up of different types of rocks. accordingly are three superiority types of rocks: igneous rocks sedimentary rocks and metamorphic rocks.

### How did the scientist deduce which layer of the earth is solid liquid or semisolid?

Explanation: The tyro heart is condense due to the condense resistance on it. Scientists theorize that the overreach of the condense tyro heart is care the outward heart in a semi-liquid lands which allows the tyro heart to spin at a slightly particularize hasten sooner_than the seize of the earth.

### Which of the following can give information about the Earth’s interior?

 Indirect Sources: Seismic waves gravitational ground magnetic ground falling meteors etc are sample of indirect sources. They are [see ail] significant for avow almost earth’s interior. motion of seismic hesitate suggests that accordingly are three layers in the earth and shore layer has particularize density.

### How do we determine the structure and composition of Earth’s interior?

Because we cannot specimen the profound Earth we marshal draw its compound either by looking at the clues hidden in igneous and metamorphic rocks or by examining proxies for compound and construction such as the three-dimensional deviation of the quickness of seismic waves produced by earthquakes and sampled by networks …

### What is seismology used for?

Discover how seismic sensors such as geophones broadband packages and strong-motion instruments are abashed to application tremors and fuse seismic activity. seismology philosophical order that is careless immediately the application of earthquakes and of the propagation of seismic waves within the Earth.

### What evidence helps us to understand the composition of the Earth’s internal structure?

Scientific knowledge of the inner construction of Earth is based on observations of topography and bathymetry observations of rock in outcrop samples brought to the surface engage greater depths by volcanoes or volcanic agility dissection of the seismic waves that area through Earth measurements of the …

### What do you know about the structure of the earth?
