Why is the earth's lithosphere considered a giant jigsaw puzzle?
Pavlova-9 [17]

The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]

Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]

Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.

Which would be an adaptation for living in the tundra?
Novosadov [1.4K]

This question is incomplete. Here's the complete question.

Which would be an adaptation for living in the tundra?

funnel shaped leaves to help water runoff

deep roots to go into the permafrost

hibernation to lower metabolism in the winter

large ears to release heat

Answer: hibernation to lower metabolism in the winter

Explanation:

Hibernation is something many animals do to survive in the tundra. They hid in dens for several months during the winter. Their metabolisms get to a dormant state in which their bodies survive thanks to stores of fat gained during the summer. The Grizzly bear is an example of a tundra animal that hibernates during the winter.
