Which techniques can scientists use to determine the characteristics of Earth's layers? Select the two correct answers.(1 point)
Responses
conduct experiments about how minerals change under high pressure
study how seismic waves travel through different layers
examine the behavior of minerals at extremely low temperatures
drill deep mines to obtain samples from Earth's mantle and core
use X-rays to obtain a view of Earth's interior layers
The two correct answers are:
1. Study how seismic waves travel through different layers
2. Drill deep mines to obtain samples from Earth's mantle and core
The two correct techniques that scientists can use to determine the characteristics of Earth's layers are:
1. Study how seismic waves travel through different layers: By analyzing how seismic waves generated by earthquakes travel through the Earth, scientists can infer information about the composition and properties of the layers they encounter.
2. Drill deep mines to obtain samples from Earth's mantle and core: By drilling deep into the Earth's crust and obtaining samples from the mantle and core, scientists can directly study the materials and properties of these layers.
The two correct techniques that scientists can use to determine the characteristics of Earth's layers are:
1. Study how seismic waves travel through different layers: Seismic waves are waves of energy that travel through the Earth's layers during an earthquake or other seismic events. By analyzing the behavior of these waves as they pass through different layers, scientists can deduce information about the composition, density, and other properties of these layers.
2. Drill deep mines to obtain samples from Earth's mantle and core: While direct access to the Earth's core is not currently possible, scientists can drill deep into the Earth's crust to obtain samples from the mantle. By analyzing the chemical and physical properties of these samples, scientists can gain insights into the composition and characteristics of the different layers of the Earth.
Conducting experiments about how minerals change under high pressure, examining the behavior of minerals at extremely low temperatures, and using X-rays to obtain a view of Earth's interior layers are not techniques commonly used to determine the characteristics of Earth's layers.
