What process causes the earths crust to continuously formed by volcanic activity?
Pressure from the earths core
What force formed these volcanic mountains?
lava formed the volcanic mountains
How can a particularly violent volcanic eruption impact global temperature?
Ash released from a volcanic eruption can enter the upper atmosphere where it can reflect sunlight. Volcanoes formed the early atmosphere of the planet, so they definitely can have global impact, an increase in agriculture does not signify a significant change in global temperature.
What was Earths first atmosphere was created by?
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
Earths early atmosphere formed during the early Archean era which gas was generally absent from the atmosphere at that time?
Oxygen Please study this, & don't forget it so you don't have to keep looking up answers .
What volcanic process most likely formed Earth's atmosphere?
Outgassing
What process causes Earth's crust to be continuously formed by volcanic activity?
Pressure from the earths core
How do geologists think earths atmosphere formed?
how do geologists think earths atmosphere is formed
What igneous rock formed from lava have a fine?
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
The first atmosphere that formed above Earth was most likely due to what process?
Volcanic release of gasses.
Which of earths layers is formed by volcanic activity?
Crust
How old is the earths atmosphere?
The earth's atmosphere is very old. It was formed when earth was formed.
How were oceans formed?
It was about 4 billion years ago, that the Earths oceans formed
How is the opening of a volcano formed?
a volcano is formed when the plates hit each other.
What type of mountain is formed when lava reaches the earths surface and piles up?
A volcanic mountain.
How are rocks formed in a volcanic eruption?
They are formed when the erupted magma or lava, cool and sollidifies below or above the earths surface respectively.
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
