How did Mt Rangitoto form?
Mt Rangitoto is a volcanic island in New Zealand's Hauraki Gulf that was formed by a series of eruptions around 600 years ago. The eruptions created a cone-shaped volcanic mountain that rises to a height of 260 meters above sea level. The lava flows from these eruptions spread out to create the distinctive landscape of the island.
Can a change on the volume of volcanic rock formed at mid ocean ridges change sea level?
Yes, a change in the volume of volcanic rock formed at mid-ocean ridges can influence sea level. When more volcanic rock is created, it can displace seawater, potentially causing a rise in sea level. Conversely, if volcanic activity decreases and less material is formed, it could lead to a drop in sea level due to reduced displacement. However, these effects are relatively small compared to other factors influencing sea level, such as thermal expansion of water and melting ice.
How do earthquakes under the sea change the sea?
thats when poo is formed
How is a cape landform formed?
Capes can be formed by glaciers, volcanoes, and changes in sea level
Does sea level change?
Yes sea levels are constantly changing.
How are fjord formed?
A fjord forms where a glacier cuts a gorge below sea level, and then retreats, allowing the sea to flood the channel. Most fjords formed during ice ages when the ocean level was lower. (see related link)
What happens to the sea level if all the sea ice melts?
Since sea ice is already located within the ocean, sea level will not change if it melts.
Are sea-level changes an impact on climate change?
No, sea level rises are a result of climate change. Warming oceans expand and so the sea level rises. Melting glaciers and ice caps also add to the rise.
What is Eustasy?
Change of sea level throughout the world.
How are new islands formed in the sea?
The sea level could have been lowered, or a volcano could have become extinct, or a coral reef could have formed, forming an archipelago and a lagoon.
Awhat is a beach called above present sea level?
A beach above present sea level is known as a fossil beach or a raised beach. These beaches were formed at sea level in the past but have been lifted up by geological processes to their current elevation.
What is the lowest country on sea level?
The lowest country on sea level is the Maldives, with an average ground level elevation of about 1.5 meters (4.9 feet) above sea level. The Maldives is at risk from rising sea levels due to climate change.
