What are lava coasts?
A
lava coast is any beach or area of land
bordering water that is covered or
composed of hardened lava.
Formation of Lava Coasts
Lava
coasts are formed when lava from an
active volcano erupts and cools along the
shoreline.
Two ways this can happen:
– Lava flows directly into sea
– Lava flows over existing shoreline
Famous Examples
The
islands of Hawaii have many
actively erupting volcanoes and lava
coasts.
Photographic Examples
Photographic Examples
Species of the Coast
The
lava is greater than 1100°C
(Explosions)
Seawater in contact with lava immediately
evaporates, sea is heated
New land is formed, ground is encrusted
Inhospitable conditions for life to survive.
Do volcanoes and global warming
mix?
A
large scale volcanic eruption can
increase all 3 major greenhouse gas
effects (ozone, greenhouse and haze)
4 major examples exist where large scale
volcanic eruptions have lowered
temperatures (including Krakatau)
Not enough is known of volcanoes to
distinguish a relationship between surface
temperatures and volcanic activity
