What is one advantage surface coal mining has over other mining techniques?
It has a smaller impact on the environment.
It’s easier to distinguish between high- and low-quality coal.
It requires more workers.
The complete seam can be accessed.
Answer:
It’s easier to distinguish between high- and low-quality coal.
Explanation:
Coal mining is the extraction of coal from the depth of the soil around the area where such coal is found. This extraction shows that, there are various grades of coal ranging from low quality which is very dangerous for use to high-quality which is better for use. The use of the surface coal mining technique will help to distinguish it based on their various colours.

Which of the following processes have contributed to the evolution of the Earth over time?
I. the motion of crustal plates
II. the rock cycle
III. radioactive dating
IV. erosion
V. deposition
A.
I and II only
B.
I, II, IV, and V only
C.
II, III, and IV only
D.
I and IV only
Answer: B. I, II, IV, and V only
Explanation:
The motion of crustal plates has led to various changes in the earth such as the formation of mountains and continents moving to other locations. The rock cycle is also significant as well as rocks make up so much of the land surface.
Erosion has moved soil from place to place and even created iconic landmarks such as the Grand Canyon. When soil is moved from one place and put in another this is called deposition.
Answer:
c
Explanation:
Erosion and weathering are examples of which types of forces?
O constructive forces
O destructive forces
O gravitational forces
O inertia-related forces
Answer:
Erosion and weathering are examples of destructive forces.

What are the three other names for x-intercept?
where do most of the energy we use comes from?
Answer:It mainly comes form fossil fuels
What are fossil fuels?
They are dead plant and or animals that have been in the ground for millions of years therefore they turn into coal fossil fuels are nonrenewable resources and cause pollution but are cheaper to use compared to solar power thats the reason we use fossil fuels rather than solar after all we can only use solar power in sunny places for example Arizona Texas Florida and Colorado
What are the main fossil fuels?
There are three kinds of fossil fuels which can all be used for energy provision coal, oil and natural gas

What is an effect surface mining has on streams?
Oxygen levels increase in the water.
Extra nutrients runoff into the streams.
Water is filtered more thoroughly.
Intermittent streams are destroyed.
Answer:
Intermittent streams are destroyed.
Explanation:
Mining which is the extraction of important resources deposited on the earth by excavation of the said land is as old as civilization. Unfortunately, some of these extraction has adverse effect on environment around it.
For example, when mining of coal is occurring, it tends to pollute the air around it causing a black soot to be found in the air. Also, if there is a nearby streams, it contaminates it.
Answer: Intermittent streams are destroyed.

How will climate affect the recovery from tsunamis?
Answer:
This means small tsunamis that might not be deadly today could wreak havoc in the future.
“Our research shows that sea-level rise can significantly increase the tsunami hazard, which means that smaller tsunamis in the future can have the same adverse impacts as big tsunamis would today,” said Robert Weiss, a professor of geosciences at Virginia Tech.
Weiss worked with the Earth Observatory of Singapore, the Nanyang Technological University and the National Taiwan University to map the dangers of future tsunamis.
He explained that small tsunamis generated by earthquakes occur frequently around the world, and may eventually be far more hazardous.
The researchers created computer-simulated tsunamis at current sea levels and then compared them to the same simulations with sea-level increases of 1.5 feet and 3 feet.
Weiss’ simulations charted the effect of a tsunami in Macau, a densely populated region in southern China.
The area is generally considered safe from the threat of tsunamis. At current sea levels, an earthquake would need to measure a magnitude of 8.8 or higher to cause “widespread tsunami inundation” in Macau.
But with a sea-level rise of 1.5 feet, the frequency of tsunami-induced flooding in the simulation rose by 2.4 times.
And for the 3-foot increase, the frequency of flooding rose to 4.7 times.
“We found that the increased inundation frequency was contributed by earthquakes of smaller magnitudes, which posed no threat at current sea level, but could cause significant inundation at higher sea-level conditions,” said Lin Lin Li, a senior research fellow at the Earth Observatory of Singapore.
Scientists used 5,000 tsunami simulations generated from “synthetic earthquakes” in the Manila Trench.
The Manila Trench is the main hazard point for large tsunamis in the South China Sea.
It hasn’t experienced an earthquake larger than magnitude 7.8 since the 16th century.
But study co-author Wang Yu said that the region shares many similarities to the source areas that led to the deadly 2004 Indonesian earthquake and Japan’s 2011 quake – both of which led to huge tsunamis.
In the future, it’s possible that smaller-magnitude earthquakes could instigate similar events – all thanks to rising sea levels.
It’s estimated that sea levels in the Macau region will increase by 1.5 feet by 2060, and by 3 feet by 2100.
“The South China Sea is an excellent starting point for such a study because it is an ocean with rapid sea-level rise and also the location of many mega cities with significant worldwide consequences if impacted,” explained Weiss.
“Sea-level rise needs to be taken into account for planning purposes, for example for reclamation efforts but also for designing protective measures, such as seawalls or green infrastructure.”
He went on: “What we assumed to be the absolute worst case a few years ago now appears to be modest for what is predicted in some locations.
“We need to study local sea-level change more comprehensively in order to create better predictive models that help to make investments in infrastructure that are or near sustainable.”
Sea levels aren’t just rising in the South China Sea – they’re rising globally.
The rise is largely attributed to global climate change: partly due to warming seas, causing “thermal expansion” of the water, and partly due to melting ice sheets and glaciers on land.
It’s estimated that we’ll see a rise of between 1 and 8 feet during the 21st century.

The lava from Mount St. Helens is made up of rock that contains around 63 percent silica minerals. The lava from Kilauea is made up of rock that contains around 50 percent silica minerals. Based on this information and your observations in parts B through E, predict at least two factors that can affect the rate at which lava flows.
Answer:
Some factors that can affect the rate at which lava flows are the steepness of the ground over which it travels, the rate of lava production at the vent and the type of lava erupted and its viscosity.

If a box of quartz weighs 10 kg (precise to ones place), how much does the same volume of corundum weigh?
(Use specific gravity.) SHOW WORK.
Answer:
1 kg
Explanation:
Because if it's precise to the ones place, then it would be 1.0 kg. So the corundum would weigh 1 kg. and your just moving the 10 over one to the right so the dot is now between 1 and 0 making it 1.0.
