Nikolay [14]

The United States experiences eruptions two or three times a year. Most of them occur in Alaska.

A volcanic eruption refers to the situation where magma is released from a volcano. Volcanic eruptions can be explosive and very dangerous. These eruptions produce lava flows, ash and pyroclastic density currents. destructive. People have died from volcanic blasts. Volcanic eruptions can cause severe threats to health through activities like floods, mudslides, power outages, drinking water contamination, and many more hazardous situations.

Savatey [412]

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.

As a deep-water wave enters shallow water, the part of the wave in the shallowest water slows down. the deeper-water portion of
Afina-wow [57]

The answer is parallel.

To add, absolute water depth has nothing to do with the difference between shallow and deep-water waves. On the other hand, the ratio of the water’s deep to the wavelength of the wave is that one that determines it. A deep-water wave’s water molecules proceed in a circular orbit while the orbit of the molecules of shallow-water waves molecules’ orbit are elliptical.

Fantom [35]

Answer:

Option (C)

Explanation:

A scale is usually defined as the ratio between the distance between two particular places on the map and the actual distance between the two places on the actual ground surface.

It is widely used by the geographers while studying a map, in order to explain the relationship between the map distance and the earth's distance.  This scale is mentioned in the map, mostly at the bottom of the map.

For example, a map scale of 1:500000, this means that 1 centimeter on the map is equivalent to 5000 meters = 5 kilometers on the ground surface.

Thus, the correct answer is option (C).

How are rocks DIFFERENT from minerals? A) Rocks are a pure substance and minerals are all mixtures. B) Rocks have no physical or
Elena L [17]

The answer is C) Rocks are made up of one or more minerals, but minerals are not made up of rocks.

Let's look into the options one by one:

A) Rocks are a pure substance and minerals are all mixtures.

-This is false.

-The fact is the exact opposite, where rocks are mixtures of minerals while minerals are pure substance. For example, granite, a type of rock, is composed of quartz, mica and feldspar.

B) Rocks have no physical or chemical properties similar to minerals.

-This is false.

-As rocks are formed by different types of minerals, often can you find the properties of rocks similar to minerals especially when one mineral component is high.

C) Rocks are made up of one or more minerals, but minerals are not made up of rocks.

-This is correct.

-Most of the rocks are made up of more than one type of minerals given the minerals are mixed together or produced during different formation. We can therefore see that minerals are not made up of rocks but a component of rocks.

For example, the granite mentioned from above is formed when intrusive volcanicity occurs, when the magma cools down, more than a type of minerals are formed, putting together forming granite.

D) Minerals are made up of at least two rocks, but rocks are not made up of minerals.

-This is false.

-As from above, minerals are not made up of rocks, while rocks are made up of minerals.

Therefore the answer is C) Rocks are made up of one or more minerals, but minerals are not made up of rocks.

Hope it helps!
