Archaeology is the study of human activity in the past, primarily through the recovery and analysis of the material culture and environmental data that has been left behind by past human populations, which includes artifactss, architecture, biofacts and cultural landscapes . Because archaeology employs a wide range of different procedures, it can be considered to be both a social science and a humanity and in the U.S, it is thought of as a branch of anthropology although in Europe it is viewed as a separate discipline.

Now the other side of the Earth is facing the Sun.
Explanation:
It is the Earth’s rotation and spinning that makes the Sun disappear at night.

Esta questão está relacionada com a proporcionalidade entre variáveis. A proporção é um valor referente a razão de dois números. Por isso, a proporção está atrelada a fração, onde temos um numerador e um denominador. Desse modo, temos uma relação de equivalência entre dois valores.
Nesse caso, vamos resolver o problema por meio da semelhança entre triângulos. A semelhança entre triângulos ocorre quando existem dois ou mais triângulos com mesmos ângulos internos. Desse modo, existe uma proporção entre suas medidas, que devem ser equivalentes sobre uma determinada razão. Portanto:
