Hey you yes you here's some information about, What is the difference between the formation and characteristics of intrusive igneous rock and extrusive igneous rock?

The major visible difference between the two are crystal size, intrusive rocks have a larger crystal/grain texture due to the slow cooling of magma below the earth surface which encourages the growth of larger crystals, while extrusive rocks, because of the rapid cooling at/above the earth's surface does the opposite.

Hope this helps!!

What environmental impacts are caused by both surface mining and underground mining? Select the two correct answers.

UkoKoshka [18]

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.

What is ironic about Lou and Em’s reaction to prison?

Law Incorporation [45]

Answer:

hope this help's its pretty long...

Explanation:

Luo is the narrator's best friend. They've been friends their whole lives, as they grew up next door to each other in the city of Chengdu. Luo is sent to the mountain to undergo re-education with the narrator, but life on the mountain makes him very depressed; he battles insomnia and moments of deep desperation. His chances of getting off the mountain are even slimmer than the narrator's because his father, the dentist, is serving time in prison. The narrator claims that Luo possesses no useful skills, but Luo is a skilled storyteller. He performs "oral cinema shows" for the village headman, in which he sees a film and then recites the film's story for the village, making his story last the length of the actual film. This earns Luo and the narrator a reprieve from their manual labor, as the process of seeing a film entails a four-day round trip journey to the city of Yong Jing and the headman agrees to pay the boys for their time. Luo is often selfish (when the boys obtain their first novel, there's no question that Luo will read it first) and convinced of his superiority. Luo is quite taken with Balzac's novels, and he sees that Balzac's work has a transformative effect on his girlfriend, the Little Seamstress. Though Luo loves the Little Seamstress, he's patronizing towards her, believing that she's uncultured and less intelligent than he is. By reading Balzac to her, Luo intends to make the Little Seamstress cultured enough to be worthy of his affections, but his education has an unintended effect: she gains the confidence and vision to leave the mountain for good by herself. Distraught, Luo burns the beloved novels in an emotional and drunken frenzy.
