Geography and Environment (CSC) World Physical Aspects

Consider the following statements:

1. Fumaroles are geothermal features that depend on the interactions of released volcanic gases and the local groundwater system.

2. The areas with fumaroles features are called “dying volcanoes” because they occur near the end stages of volcanic activity.

3. Mudpots are surface features that occur when limited amount of geothermal water is mixed with mud and clay.

Explanation:

Correct option: (c) Explanation: All statements are correct Supplementary notes: Geothermal Features Fumaroles They are geothermal features that depend on the interactions of released volcanic gases and the local groundwater system. These occur in areas where a magma conduit passes through the water table. The magma can be liquid or recently solidi fi ed, but still hot. The heat from the magma causes water to become steam. As the steam rises it carries volcanic gases such as hydrogen sul fi de (H2S) to the surface. This mixture of steam and gas is erupted from vents and fi ssures in the ground. Due to this chemical activity, fumaroles can be very dangerous. Associated chemical reactions can color the surrounding rocks. Areas with fumarole features are sometimes called “dying volcanoes” because they occur near the end stages of volcanic activity as the magma deep underground solidi fi es and cools.

Mudpots They are surface features that occur when limited amount of geothermal water is mixed with mud and clay. Acid and bacteria in the water can dissolve surrounding rock forming viscous pools of bubbling mud.
