What asteroid caused the ice age?
The ice age was not caused by an asteroid impact. It was most likely due to a combination of factors such as changes in Earth's orbit and axial tilt, volcanic activity, and the release of greenhouse gases.
Why did Australia have volcanic activity even though it is not located on a plate edge?
Australia's volcanic activity is due to the presence of a hot spot beneath the Earth's crust. This hotspot, located in the southeast of Australia, has caused volcanic activity in the past. The volcanic activity in Australia is not related to plate tectonics like the Ring of Fire, where most volcanic activity occurs.
Which are other natural hazards that can occur due to volcanic activity?
Fires
What are in sinkholes in the the ocean?
an empty cavity or cavern due to drilling or possibly earthquake activity or volcanic activity
What is the relationship between seamount and volcanic island?
A seamount is an underwater mountain formed by volcanic activity, while a volcanic island is a landmass that rises above the ocean's surface due to volcanic eruptions. Seamounts can eventually grow to become volcanic islands if the volcanic activity continues and brings the seamount above the water level.
What are 3 reasons for mass extinction?
Mass extinction could occur due to climate change, an asteroid impact and even a volcanic eruption.
What can kill a dinosaur?
Dinosaurs became extinct around 65 million years ago due to a combination of factors, primarily believed to be a large asteroid impact and volcanic activity. Other factors such as climate change and disease may have also contributed to their extinction.
How did the gases from the volcanic activity form the earth's early atmosphere?
Volcanic activity released gases such as water vapor, carbon dioxide, methane, and ammonia. These gases accumulated to form the Earth's early atmosphere through processes like outgassing, where gases trapped in the Earth's interior were released during volcanic eruptions. Over time, the composition of the atmosphere changed due to processes like the formation of oceans and the evolution of life.
How many volcanoes are there in Delaware?
There are no active volcanoes in Delaware. Delaware does not have any history of volcanic activity due to its location away from tectonic plate boundaries where most volcanic activity occurs.
Explain the abundance of andesite of leyte?
Andesite is abundant in Leyte due to the volcanic activity in the region. Leyte is part of the Pacific Ring of Fire, a region known for its high volcanic activity, which has resulted in the widespread presence of andesite. This volcanic rock is formed from the solidification of magma beneath the Earth's surface and is commonly found in areas with past or present volcanic activity.
What is the proper name for black sand?
Black sand is typically known as "volcanic sand" due to its origins from volcanic activity. It is formed from the erosion and weathering of volcanic rocks and contains minerals such as basalt, magnetite, and volcanic glass.
When did the last dinosour die out?
The last dinosaurs died out around 65 million years ago during the Cretaceous-Paleogene extinction event, likely due to a combination of factors such as a massive asteroid impact and volcanic activity. Some smaller dinosaur species may have evolved into modern birds.
