What are tectonic plates

la respuesta es que te acaban de apuntar

Explanation:

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century

A tectonic plate is a massive, irregularly shaped slab of solid rock. (via https://pubs.usgs.gov/gip/dynamic/tectonic.html)

Explanation:

The Earth’s outer shell is divided into a patchwork of large tectonic plates that move slowly relatively to each other. (via https://www.gns.cri.nz/Home/Learning/Science-Topics/Earthquakes/Earthquakes-at-a-Plate-Boundary/Tectonic-Plates-and-Plate-Boundaries)

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
