Here we tried to reproduce the global surface color of Venus as seen by the human eye based on radar imagery from the Magellan spacecraft and surface images by the Venera missions.There are no color global images of the surface of Venus due to its thick atmospheric coverage and colorized radar images are used instead.ere we tried to reproduce the global surface color of Venus as seen by the human eye based on radar imagery from the Magellan spacecraft and surface images by the Venera missions.
A volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface. Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent. A volcano is active if it is erupting lava, releasing gas or generates seismic activity.

Carbonic acid is formed when water combines with carbon dioxide. Carbonic acid dissolves or breaks down minerals in the rock.hemical weathering is the weakening and subsequent disintegration of rock by chemical reactions. These reactions include oxidation, hydrolysis, and carbonation. These processes either form or destroy minerals, thus altering the nature of the rockâs mineral composition.
