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:
The routes show that most of the slaves were going to the colonies in the Americas
Explanation:
The slave trade was very big during the colonial period. The Portuguese were the first ones to start buying slaves from Africa, and the world quickly spread around, so the other colonial powers started to do so. The main reason why the slave trade became so big was because the colonies in the Americas primarily had huge demand for labor force for the enormous plantations of cash crops. The slaves were seen as ideal labor force, as they were obtained easily, they were paid nothing for their work, but only provided simple shelter and food. This resulted in mass forceful migration of Africans toward the Americas, which in the time to come contributed to the culture and demographic composition of the New World.
