Earth's Interior QUIZ 100%
Which statement describes how the mantle is similar to Earth's oceanic crust? - It is composed mostly of basalt. - It consists primarily of molten rock. - It has varying degrees of thickness. - It is divided into two layers.
It has varying degrees of thickness.
Study the image of Earth's layers. Which statement correctly compares the thicknesses of Earth's layers? - Earth's mantle is thinner than its oceanic crust. - Earth's outer core is thicker than its mantle. - Earth's continental crust is thicker than its lithosphere. - Earth's lithosphere is thinner than its asthenosphere
Earth's lithosphere is thinner than its asthenosphere.
Study the graph about seismic waves. What does the graph show? - The S and P waves travel the same distance through Earth's crust in the same amount of time. - The P wave travels through Earth's crust more quickly than the S wave travels. - It takes the P wave 18 minutes to travel 6,000 km through Earth's crust. - It takes the S wave 11 minutes to travel 8,000 km through Earth's crust.
The P wave travels through Earth's crust more quickly than the S wave travels.
Study the table about Earth's interior. Which conclusion is supported by information in the table? - The mantle is thinner than the crust. - The core is the thickest of Earth's layers. - The inner core is thicker than the outer core. - The mantle is the thinnest of Earth's layers.
The core is the thickest of Earth's layers.
Study the diagram showing the range of temperature in the Earth's layers. What does the diagram show about Earth's interior? - The outer core is the hottest region. - The mantle is hotter than the outer core. - The continental crust is the coolest region. - The inner core is cooler than the lithosphere.
The continental crust is the coolest region.
Which region of Earth's crust experiences the least amount of pressure? - crust - mantle - outer core - inner core
crust
Study the diagram about the varying pressures of Earth's Layers. Which is the best estimated pressure, represented in units of GPa, of the lower mantle? - 110 GPa -220 GPa - 305 GPa - 360 GPa
110 GPa
Study the image of a seismic graph. About how far does the S wave travel through Earth in 13 minutes? - 2,000 km - 4,000 km - 6,000 km - 8,000 km
4,000 km
Which statement describes a difference between the lower mantle and oceanic crust? - The lower mantle is closer to Earth's surface than oceanic crust is. - The lower mantle is found closer to sea level than oceanic crust is. - The lower mantle experiences more pressure than oceanic crust does. - The lower mantle has a more tarry consistency than oceanic crust does.
The lower mantle experiences more pressure than oceanic crust does.
A scientist collects a core sample from 60 km deep in Earth. Which characteristic will she most likely observe in this sample? - The sample has high iron content. - The sample is very hot and liquefied. - The sample mainly consists of granite. - The sample has a very high density.
The sample mainly consists of granite.
