Answer:
Upper Lithosphere / crust:
The Magma density was equal to or less than the crust
The Magma underwent a degassing during an eruption.
Lower Lithosphere:
The Magma density was less than in the lower lithosphere but higher at crust.
Magma undergoing partial crystallization of high-density minerals
Asthenosphere:
The Magma with the high temperature.
Explanation:
The greenhouse effect is exacerbated by the use of fossil fuels.
Answer:
Active volcanoes are used as evidence for the location of the boundaries of tectonic plates because they often occur along the edges of these plates. When tectonic plates collide, move apart, or slide next to each other, it can cause magma to rise to the surface and create a series of active volcanoes. So, the presence of active volcanoes along the boundaries of tectonic plates provides evidence for the location of these boundaries.
Answer:
Active volcanoes are used as evidence for the location of the boundaries of the floating rocks because they occur at the boundaries of tectonic plates where molten rock (magma) rises to the surface and forms volcanoes. The magma that forms these volcanoes is believed to come from the partially molten rock in the Earth's mantle, which is closer to the surface at the boundaries between tectonic plates. By studying the locations of active volcanoes, scientists can determine the approximate location of the boundaries between these plates and the areas where the plates are moving away from or towards each other. This information is important for understanding the geology of the Earth and for predicting and managing volcanic hazards.

TRUE
Explanation:
GPS stands for Global Positioning System, and consists of satellite tracking technology.
GPS receivers, like satellites, have an internal clock that marks the time with incredibly high accuracy in nanoseconds. When the satellite sends the signal to the receiver, the time it left the satellite is also sent.
The sending of these signals is constant. This signal sent to the receiver is a radio signal, which travels at a speed of 300,000 kilometers per second (this speed is known as the speed of light !!) in a vacuum. It remains for the receiver to calculate how many nanoseconds this signal took to reach him, so he can "figure out" where you are. And because the signal is constantly being sent, the receiver always knows where the satellite is, thus keeping its exact position always up to date.
GPS uses a system called triangulation to determine the location of the receiver on earth. The triangulation works as follows: three satellites send the signal to the receiver, which calculates how long each signal took to reach it.
In addition to its terrestrial location, the GPS receiver can also know the receiver's height from sea level, but a fourth satellite is required.
