Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.

Answer:
B. local water contamination
D. destruction of ecosystems
Explanation:
The mining, be it a surface one or underground one, has several negative impacts on the surrounding area. Two common negative impacts of both types of mining are contamination of the local waters, as well as the destruction of ecosystems.
The waters get heavily polluted with toxic chemicals pretty much always ad everywhere where there is mining. The main reason for this is that the nus-products from the mining are released into the waters. This causes high level pollution of the waters, thus making it not good for anything, and the aquatic life in the waters dies out rapidly.
The fact that the waters are heavily polluted means that everything that comes in touch with them becomes heavily polluted as well. Also, apart from releasing chemicals in the waters, the mining requires space, so the area is cleared out, and after that lot of toxic material is disposed on it. The majority of the plants can sustain that, so they die out, and since they are the basis of the ecosystems, the animals die out as well.
Answer:
"Dr. Randall Irmis is a famous paleontologist, who has gone on to make important discoveries since he showed the Penn State CAUSE class this fossil plate from the armored vertebrate Buettneria."
Explanation:
<u>Based on the discussions in the textbook and lecture on the topic of evolution, it is likely that:
</u>
- All species alive today are completely unrelated to Buettneria.
- Some species alive today are essentially identical to Buettneria.
- The most similar species alive today are related to but recognizably different from Buettneria.
