Answer:
Actividades industriales.
Explanation:
La industria es la parte de la economía que produce bienes y proporciona servicios, a partir de la modificación de las materias primas obtenidas de la naturaleza.
La industria se puede dividir en cuatro partes. La primera parte son las industrias donde los recursos naturales se convierten en productos como la minería, la tala y la agricultura. La segunda parte son las industrias en las que las materias primas se convierten en productos, como la automoción y la siderurgia. La tercera parte son las industrias de servicios como el comercio y la banca. La cuarta parte es la investigación, el diseño y el desarrollo que pueden conducir al cambio y al progreso tecnológico. Los países en desarrollo suelen tener economías basadas más en la primera y segunda partes, mientras que en los países industrializados se pone más énfasis en la tercera y cuarta partes que en los países en desarrollo.
Answer:
<em>The correct option is theories. </em>
Explanation:
A scientific theory is a detailed explanation of natural researches which are supported through evidence. Scientific theories can be changed if other evidence are made which support another theory. Hence, scientific theories can change. The concepts of plate tectonics and evolution change overtime whenever new pieces of evidence are discovered. Hence, they are scientific theories.
Other options such as hypotheses are not correct because a hypothesis is just a tentative statement which can either be proved to be correct or wrong. Observations are not made on evidences hence the option observations is also not correct.
Answer:
C. The greater an element's density, the smaller the amount of it found in the crust
Explanation:
The layering of the Earth happened because of the different densities of the elements from which it was made. The denser elements started to sink deeper, the elements with medium density occupied the central part, and the elements with the smallest density remained at the surface. This resulted in the formation of the three basic layers of the Earth, core, mantle and crust. The core is composed of the densest elements, the mantle of the ones with medium density, and the crust from the ones with smallest density.
