Unit 3 Plate Tectonics Pt. 1

Who presented a model of Earth's structure in the late 1600s?

• Isaac Newton

• Edmond Halley

• Galileo Galilei

• Johannes Kepler

What is the depth of the Kola Superdeep Borehole, the deepest hole ever drilled?

• 12,261 meters

• 10,000 meters

• 15,000 meters

• 8,000 meters

How are Earth's structural layers, such as the lithosphere and asthenosphere, distinguished?

• By their chemical composition

• By their physical properties such as temperature and physical state

• By their color and texture

• By their size and shape

What is the formula for the volume of a sphere?

• V = 4/3 πr²

• V = 4/3 πr³

• V = 2/3 πr³

• V = πr²

Why do some stony meteorites remain undifferentiated?

• They come from small objects that never went through differentiation.

• They are formed by volcanic activity on Earth.

• They are made of Earth's crust material.

• They are identical to Earth's mantle.

What is one method scientists use to simulate the conditions of Earth's deep interior in the lab?

• Using a diamond anvil cell to generate pressure and heat samples with a laser

• Drilling directly into Earth's core

• Collecting rock samples from the ocean floor

• Measuring Earth's magnetic field

What is the primary reason Earth's lithosphere does not experience convection in the same way as the mantle below?

• It is cold and rigid.

• It is heated by solar energy.

• It is composed of liquid rock.

• It is constantly eroded by weathering.

What is seismic tomography primarily used for?

• To study the Earth's surface features.

• To analyze seismic wave data and create detailed models of Earth's interior.

• To measure the Earth's magnetic field.

• To predict weather patterns.

What do the red areas in the seismic tomography diagram represent?

• Areas where seismic waves travel faster than expected.

• Areas where seismic waves travel slower than expected.

• Areas with no seismic activity.

• Areas with the highest temperature.

Why are Halley's models of Earth's interior considered incorrect today?

• They were based on observations and measurements unavailable at the time

• They are inconsistent with modern scientific evidence, such as seismic data

• They suggested the Earth was solid throughout

• They were based on magnetic field measurements
