A direct source of material for the formation of metamorphic rock is: D. existing rock.
What is a metamorphic rock?A metamorphic rock can be defined as a type of rock which is typically formed as a result of the transformation of an existing rock, especially when it undergoes certain chemical and physical processes such as:
High heatHigh pressureHot mineral-rich fluids.This ultimately implies that, an existing rock serves as a direct source of material for the formation of metamorphic rock.

How does climate affect Tōhuko?
Answer:
When the global temperature changes, the changes in climate are not expected to be uniform across the Earth. In particular, land areas change more quickly than oceans, and northern high latitudes change more quickly than the tropics, and the margins of biome regions change faster than do their cores.
Explain what the Social Contract is in your own words.
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.

Which factor contributes to the formation of tides that turn turbines to create energy in the ocean?
Answer:
using the power of the tides,energy is produced from the gravitational pull from both the moon and the sun, wich pulls water upwards, while the earths rotational and gravitational power pulls water down, thus creating high and low tides.

How do scientists know about the levels of carbon in our atmosphere now and in the past?
Answer:
The Earth also gives us clues about the levels of greenhouse gases that existed in the past. For example, ancient air bubbles trapped deep in the ice of Greenland and Antarctica reveal how much carbon dioxide was present long ago.

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.
