Which statement about basaltic magma is false?
a. It forms when rocks in the upper mantle melt
b. It contains small amounts of silica
c. It has high viscosity
d. It forms on oceanic and continental crust
Basaltic magmas tend to be fairly fluid (low viscosity).
So, C.
The statement, that is, basaltic magma has high viscosity is false.
• The molten rock enriched in magnesium and iron and less amount of silica is known as the mafic lava or basaltic magma.
• The density of basaltic magma is very high and thus it gets stopped in the continental crust and get crystallize. Thus it forms on oceanic and continental crust.
• Basaltic magma is generally produced by direct melting of the mantle part of the Earth, that is, the part of the Earth underneath the outer crust.
• The viscosity of basaltic magma is very less, that is, it exhibits low viscosity. However, it is 10000 to 100000 times more viscous in comparison to water.
Thus, the false statement is option c.

Explanation:
Answer:
a testable prediction that regards the possible outcomes of a study. (aka an educated guess)
Explanation:
The initial building block in the scientific method is a scientific hypothesis. It is defined by many as a "informed guess," based on prior experience and observation. While this is true, the definition can be extended. The theory also provides an interpretation as to why the assumption could be right.

On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 84–87% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.
Computer modeling can be used to help improve cleanup and response systems for the next major oil spill. Which of these uses demonstrates how computer modeling can be used to minimize the impact of another spill?
a
Creating a model of how the oil spread through the Gulf of Mexico to predict what areas need the greatest amount of protection.
b
Calculating the total oil that entered the Gulf of Mexico during the spill.
c
Recording the number and type of each dead organism collected during the spill.
d
Finding the average flow rate of the oil through the burst pipeline during the spill.
Answer:
I would pick a, because if you can see where the most oil spills or where it flows it will be easier to predict when another spill is about to happen.

Why is flooding more likely after many trees are removed from an area?
A. Without the trees, evaporation rates slow down.
B. Without the trees, water runs off rather than percolating into the
soil.
C. Without the trees, most of the animals die and therefore don't
drink the water.
D. Without the trees, precipitation increases dramatically.
SUBMIT
Answer:
Without the trees, water runs off rather than percolating into the
soil.
Explanation:
Flooding is the excessive flow of water due to increased rainfall. It usually deprives the soil of the affected area of essential nutrients. However, the presence of trees in an area can help prevent or reduce the possibility of flooding. The roots of large trees help hold the soil together, which improves the porousness of the soil. Also, trees store water that is meant to runoff.
Without the trees, the absorption or percolation of water into the ground/soil will be reduced, hence, the excess water runsoff the surface leading to flooding.
