Questões de EFAF Ciências - Terra

     Quando crianças são solicitadas a representar o planeta Terra, com as pessoas  e o céu, os desenhos obtidos podem revelar certas surpresas. A seguir, são apresentados desenhos realizados por quatro crianças.

A representação que mais se aproxima da atual compreensão científica corresponde ao desenho da criança

“Exploring volcanoes is risky business. That’s why Carolyn Parcheta and her co-advisor, JPL robotics researcher Aaron Parness, are developing robots that can get into crevices where humans wouldn’t be able to go, gaining new insights about these wondrous geological features. (...) The research has implications for extraterrestrial volcanoes. On both Earth and Mars, fissures are the most common physical features from which magma erupts. This is probably also true for the previously active volcanoes on the moon, Mercury, Enceladus and Europa, although the mechanism of volcanic eruption -- whether past or present -- on these other planetary bodies is unknown, Parcheta said.
(...) Parcheta, Parness, and JPL co-advisor Karl Mitchell first explored this idea last year using a
two-wheeled robot they call VolcanoBot 1, with a length of 12 inches (30 centimeters) and 6.7-
inch (17-centimeter) wheels. (...) For their experiments in May 2014, they had VolcanoBot 1 roll
down a fissure – a crack that erupts magma – that is now inactive on the active Kilauea volcano in
Hawaii. Finding preserved and accessible fissures is rare. VolcanoBot 1 was tasked with mapping
the pathways of magma from May 5 to 9, 2014. It was able to descend to depths of 82 feet (25
meters) in two locations on the fissure, although it could have gone deeper with a longer tether, as
the bottom was not reached on either descent.”
