The evidence of the theory of continental drift can be found on the edges of the tectonic plates. For example, the boundary of the African Plate and the Eurasian plate is in the Mediterranean Sea, just south of the island of Crete. At this boundary, scientists have observed that the Eurasian Plate is sliding under the African Plate at a rate of three to four centimeters per year as the African Plate drifts north

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.

both Pakistan and India have claimed the Kashmir region the situation has resulted in which of the following consequences
Aloiza [94]
Relations between the two states have been defined by the violent partition of British India in 1947, the Kashmir conflict and the numerous military conflicts fought between the two nations. Consequently, their relationship has been plagued by hostility and suspicion. Northern India and Pakistan somewhat overlap in areas of certain demographics, shared lingua francas (mainly Punjabi and Hindustani) and shared cuisines inherited from the Mughal Empire.

In terms of symbolizing a geologic unit/formation, which is not true? a) The first capitalized letter stands for the system/epoc
kkurt [141]

Answer:

C. The formation name is symbolized by capital letters

Explanation:

The capital letter represents the the age of the geological unit and not the formation name. The history of the Earth has been divided by Geologists into Eons (the largest division), Eras, Periods, and Epochs , mostly based on the fossils found in rocks.
