What is capillarity in Earth Science?Capillarity:Capillarity (also known as capillary action) refers to the process in which a liquid is able to travel through a narrow tube or vessel without any help or assistance. Additionally, this flow of a liquid through a narrow tube or vessel can ...
Earth science is mainly divided into four fields: Geology Astronomy Oceanography Meteorology Geology Geology is the study of different materials, structures, and crust of Earth. It also includes the study of processes that create them. The vast knowledge of the field is segregated into sub-categorie...
In Iceland,volcanoes appear to be respondingto rapid glacier retreat. As ice melts, less pressure is exerted on the Earth's crust and mantle. (Civil Protection of Iceland/Handout via REUTERS) Volcanologists worry this could destabilize magma...
Mohorovicic knew this and hypothesized that a different material must be below Earth's crust that caused the refraction of the seismic waves. He published his finding in a 1919 journal — the first person to introduce the idea that there is a sharp boundary made up of a different material ...
Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other. Earthquakes are most common along fault lines, which are fractures that allow the plates to move. ...

Earth is the densest of our Solar System's rocky planets, all of which share a composition rich in silicon. Silicate rock makes up the Earth's crust and the towering bulk of its mountain ranges. Igneous and metamorphic rocks are loaded with it. Sand, too, is mostly grains of silicates ...
One of these changes is shock-fractured quartz grains. Bits of quartz (a common mineral in the earth's crust) will break in an unusual way only from intense heat and pressure. The only other place shock-fractured quartz is found is at ground zero of atomic explosions (where a nuclear ...
