1: When did Mt. St. Helens erupt last?
Erupted on October 2004
2: Where is Mt. St. Helens located?
It's located in Washington State
3: How much magma is released during the eruption?
Millions of tons.
4: What is a pyroclastic flow?
Pyroclastic flow is a lava fragments, and gases ejected explosively from a volcano and typically flowing downslope at great speed.
5: How far from the summit is Spirit Lake located?
About 4 miles from the summit.
6: How many people were killed by the eruption?
57 people were killed
7: How far away was the furthest victim?
13 miles away
8: How many birds disappeared during this disaster? How many insects?
Thousands of birds disappeared and about billions of insects also disappeared.
9: What happens to Spirit Lake? Explain.
The Spirit Lake were filled with dead trees and hundreds of marine animals that is living in the lake were found dead. Also the water was hardly clear.
10: Explain what the landscape in this region looks like after the eruption. (End of Part I)
After the cause of the eruption it left a mile wide crater that was measure of two thousand feet deep.
11: What is the “Pacific Ring of Fire”?
Pacific Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean.
12: Explain what has caused the volcano at Mt. St. Helens.
The cause of the Mt. St. Helens to erupt is by the two plates comes together from different direction and also by the subsiding under the North America plate creating the magma to build up.
13: What did the ecologist find when he first came to the mountain after the eruption?
The ecologist found after the eruption is a place full with dead animals and trees fill with thick ashes.
14: What were the first signs of life at the mountain? What did they see happening?
The first sign of life at the mountain are the fresh dirt soil. They see a pocket gopher.
15: Why were ecologists so surprised to see a flowering plant a year after the eruption? (End of
Part II)
They were surprised because it was the first sign that grew after the eruption.
16: How has the plant managed to grow in such a barren area? Explain.
The plant managed to grow by pervaded its own fertilizer, and also the bacterium helps the plant to provides its nitrogen, and gives the bacterium a simple sugar.
17: What is a pioneering species? How do they help out in a nutrient poor environment?
Explain.
Pioneering species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem. It helps by releasing nutrients into the soil.
18: What is causing earthquakes on Mt. St. Helens?
The causing earthquakes on Mt. St. Helens is the lava that is breaking into rocks and flowing through the crater floor.
19: Explain how the pioneering species are helping to revive the landscape.
The pioneering species are helping to revive dead landscape by releasing nutrients into soil when the pioneering die called enriches, and the enriches soils helps the plant to grow.
20: What were scientists finding in Spirit Lake? Why was the dissolved oxygen levels so low?
What was this causing?
They find a lot of bacteria. The dissolved oxygen level is low because of the bacteria consuming them. This causing a life possible underwater.
21: Explain how life in the lake is able to come back. What species is first (pioneering species)?
How were they brought to the lake? (End of Part III)
The life in the lake is able to come back because the phytoplankton turns into the sunlight oxygen. The pioneering species were the pythoplankton. They brought to the lake by birds or blow by winds.
22: How are the salamanders able to survive in the harsh environment?
The salamanders were able to survive cause of the tunnels that gophers created.
23: How was the rate of recovery on the mountain? Was it was scientists expected? (End of Part
IV)
The rate of recover on the mountain was shock-able because of organism and plants came back by small steps. The scientist didn't expected that life will come back after the eruption it cause.
24: Where does all of the explosive force in volcanoes come from? Where does the gas come
from? (End of Part V)
The explosive force in the volcanoes came from the gas that gives pressure to the magma and the gas is created from water, which is a component from magma.
Discuss the miraculous return of nature to Mt. St. Helens years after the eruption. In your
discussion, use the following terms in your answer: succession, pioneer species, symbiosis
(mutualism), and nutrient cycling
The return to life of the nature to the biggest eruption of Mt. St. Helens started from the secondary succession. The Secondary succession is a place that has soil but once had living organism. Next is the pioneer species such as the Northern Pocket Gopher that been digging soils to the surface. That started to grow a plant to colonize the ecosystem. The is able to survive because of its provided with its own fertilize and when the plants die it lead to enrichment of soil which gives nutrients. For the Spirit Lake the pioneering species were the phytoplankton which gives the life underwater. It work fish to give them both a benefit to live in the lake.
