Assuming this is a write-in question:

Volcanoes can create new land entirely. When a volcano erupts, lava flows down and cools. As it cools, it hardens into new land. The ash that falls onto the ground it can destroy entire ecosystems, but also works as an extremely effective fertilizer. The reason the Hawaiin islands exist is because of volcanic eruptions.

15. Three types of volcanoes that we discussed in class characteristics of each.

Setler [38]

Answer:

Explanation:

The three main types of volcanoes are as follows:

1. Composite volcanoes: These are also called as strato volcanoes. These are steep and formed by the layers of ashes and lava. The eruption from these volcanoes is in the form of pyroclastic flow. The pyroclastic flow is in the form of superheated mixture which consists of rock dust, ash, and hot steam. These volcanoes can rise above the 8000 feet. These are found in the destructive plate margins. Example of these volcanoes include the Mount Fuji in Japan.

2. Shield Volcanoes: These volcanoes are low and they have gentle sloping sides. These are formed by the layers of lava. Their eruption of lava is non-explosive. These produces the fast flowing fluids that can flow to many miles. These can destroy the nearby surrounding regions can cause injury and even death. These volcanoes are found in the region of constructive boundaries and also at the volcanic hotspots. The examples of shield volcanoes include the Maunaloa on Hawaii.

3. Dome volcanoes: These are also called as acid lava cones as these emit acid which is much thicker than that of the lava. These have steeper sides as compared to the shield volcanoes. The lava is thick and sticky as a result of this it cannot flow to far region and it cools and solidifies. The example of dome volcanoes include the Puy de Dome of Auvergne, France.

Answer:

My thoughts as below.

Explanation:

Climate change s the process of changes in the level of global sea level and climatic weather patterns around the world that affects the entire ecosystem and carrying capacity of the earth hence, the climate has become such a great phenomenon and the need to address this is quite large.

climate change includes the depletion of ozone that is natural gas that encircles and protects the earth from the harmful effects of the sun and solar activity. We, humans, have destroyed the sustainable fashion of the planet to protect itself at the time of any violent catastrophes.

The grave threat of climate is being realized currently due to the face the climate now is getting out of the hands of the people and this is evident in form of flooding that occurs every tear massive depletion of natural resources and emissions of greenhouse gases.

And the continuous release of harmful gases on earth and the depletion of resources that are needed for the future of the planet is causing many humans to think of living on the moon and other earth-like planets.
