The model demonstrates the differences between the types of tectonic plates and the resulting observations in the asthenosphere there are two foremost sorts of tectonic plates: Oceanic and Continental. Continental crust is often fashioned of granite and is typically referred to as sial because of a large amount of silica and aluminum gift. Continental crust is much less dense than the basaltic oceanic crust, sima, which is constructed from silica and magnesium. Due to the fact it's far denser, oceanic crust plunges beneath the continental crust. The department between the 2 layers is known as the Conrad Discontinuity.
Asthenosphere, a sector of Earth's mantle mendacity beneath the lithosphere and believed to be a whole lot hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) underneath Earth's floor. Cross-section of a tectonic plate.
It's miles a layer of stable rock where the intense pressure and warmth cause the rocks to flow like a liquid. The rocks in the asthenosphere are not as dense because of the rocks in the lithosphere. This allows the tectonic plates within the lithosphere to move around on the planet's floor.
The asthenosphere is the robotically weak and ductile vicinity of the upper mantle of Earth. It lies underneath the lithosphere, between approximately 80 and two hundred km below the surface, and extends as deep as seven-hundred km. But, the decreased boundary of the asthenosphere isn't always well described.

Answer:
Option B
Explanation:
Tuttle and Bowen conducted a study in 1958 after which the study of modern granite started. They also determined whether granite is igneous rock or not. Some of the prominent remarks that were concluded after the experiment by Tuttle and Bowen are
- A) When a silicate is melted at lower temperature, it contain equal proportions of Ab, Q and Or
- B) Felsic rock form at the end of the fractional crystallization of mafic rock
C) Determined the temperature and pressure at which high and low granite crystal melts and what is the impact on melting if Ab, Q and Or are present
Answer:
Natural resource depletion can destabilize livelihoods, negatively affecting ecosystems, and undermine peace and development. Exploitation of natural resources is a key factor in economic growth and development, and also one that can have serious negative environmental and socioeconomic impacts.

Human beliefs, and how they view the world around them. That is the source of ideology. Every source of any ideology is the birth of power to set the ideology through; and the ideology does die when the only idea left is power
