Answer:
D: modern technology
Explanation:
Modern technology was usually imported from other countries and was not a domestic resource to Africa.
D. the collision produces spectacular mountain ranges
When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges.
They are increasing due to longer life expectancies, because of the increase of technology, and the increase of regulations in the workforce ex. Britian in the Industrial revolution
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.

The reason why Greenland is so sparsely populated is because, despite its name, Greenland is actually covered with ice (almost 80% of the territory is ice), meaning that it's very hard for people to settle.
