ppefmh	Ed	Garstin	8/18	The diagram below shows the internal structure of the Earth.		Inner core Mantle Crust Outer core	Solid with a maximum depth of 50 km Solid but can flow at the very upper region This is solid This is liquid	Inner core Mantle Crust Outer core	Solid with a maximum depth of 50 km Solid but can flow at the very upper region This is solid This is liquid	Inner core Mantle Crust Outer core	Solid with a maximum depth of 50 km Solid but can flow at the very upper region This is solid This is liquid	Inner core Mantle Crust Outer core	Solid with a maximum depth of 50 km Solid but can flow at the very upper region This is solid This is liquid	Scientists cannot directly observe the Earth's interior. This is because the Earth's crust has a maximum depth of 50 km but the deepest mines only go to a depth of a few kilometres into the crust. Scientists cannot directly observe the Earth's interior. This is because the Earth's crust has a maximum depth of 5 km but the deepest mines only go to a depth of a few kilometres into the crust. Scientists cannot directly observe the Earth's because the interior is too hot. This is because the Earth's crust has a maximum heat of 50 kelvin.	1c) Complete the sentences below by selecting the correct missing words.	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	earthquakes tectonic Seismic seismometers interior longitudinal solids transverse slowly	44%
