CINDER CONE VOLCANO The cinder cone volcano‚ commonly found in volcanic areas‚ are constructed of rocks and ashes. Gas created from the lava is blown into the air which then “cools and solidifies as small rocks or cinders”. Cinder cone eruptions “take place in basaltic volcanic fields” that immensely effect the human population surrounded by it. Cinder cone eruptions majorly impact the environment by distributing volcanic gases‚ volcanic landslides and blasting tephra. One of the long-term impacts

into the city of Los Angeles‚ California. The evaporating of harmful gases‚ earthquakes‚ and some evidences from the manhole are the manifestations showed that an underground volcano was forming under the city. This means that there was already lava under the city and the ground cannot take the pressure anymore so it formed a volcano. The physical changes in the movie are the breaking of glasses from buildings‚ breaking of buildings‚ cracking of the ground‚ boiling of water from the pond‚

Most people are unfamiliar with the positives of Volcanoes. Volcanoes do cause destruction to people’s houses (and other things) but‚ the ash‚ rocks‚ lava‚ etc. improves the landscapes and the environment. It also makes great soil for farming‚ crops‚ and tilling. They are improving the natural scenery of the land and creating food and work for the people. The volcanoes affect the land in a good way because it is helping to improve our environment/earth. Nowadays‚ people don’t see difference

Professor Radcliffe Geology 1 Lab Report December 10‚ 2012 Geology of the Caribbean Islands Have you ever wondered how the famous tropical land masses located in Central America‚ known as the Caribbean Islands‚ came to existence? Well geologists have dated some of the rocks in the islands such as‚ Cuba and Trinidad‚ as far back as the Jurassic time period. This means the rocks formed about 145-200 million years ago‚ therefore the eldest islands from the Caribbean date way back to the time

To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) A volcanic hazard is a situation that poses a threat to life‚ the environment‚ and infrastructure after a volcanic eruption. Volcanoes are formed at various plate boundaries‚ such as at mid oceanic ridges where plates are moving apart‚ for example at the Mid Atlantic ridge. They also occur on or near subduction zones. The ‘ring of fire’ tends to be where the most violent volcanic activity occurs.

Volcanoes are generally not preserved in the geologic rock record as they are usually eroded away. However‚ the various materials erupted from volcanoes are often found preserved in the rock record. From what you have learned about the different types of volcanoes‚ how could you infer what type of volcano erupted in a given area based on the type of volcanic deposits now found as layers of rock? Give specific examples‚ and briefly discuss how some materials may be linked to different types of volcanoes

There are two types of volcanic flows pyroclastic and mud flows. Pyroclastic volcanoes occur when the amount of magma in the chamber collects and the pressure increases causing the volcano to erupt. Mud flows are kind of like pyroclastic accept the lava in the chamber doesn’t collect and cause an eruption it just flows out the top of the volcano. Mount Etna is located on the island of silicon‚
