Igneous rock composition however is dictated by the amount of silica present in the rock. high silica content will result in a Felsic composition.
A silicate mineral, magma, or rock that is abundant in lighter elements including silicon, oxygen, aluminum, sodium, and potassium is referred to as felsic. In comparison to mafic magma/lava, felsic material has a greater viscosity.
The term "felsic" in geology refers to igneous rocks that are highly abundant in the components that go into making feldspar and quartz. Felsic rocks often have light colors and specific gravities under 3. Granite is the most typical felsic rock. Rocks classified as felsic have a silica concentration greater than 65 percent according to a frequently used categorization system. Rhyolite and granite are felsic rocks, having an average silica concentration of roughly 72%, according to compilations of several rock studies.

why do scientists send space probes instead of people? pls help guys
The reason why scientists send space probes instead of people is because sending a space probe is cheaper and safer.
Why are space probes sent?Space probes are sent in the place of people because scientists often do not have to spend as much on a space probe as they would on a space vessel that would have to take humans into space.
Also, if something goes wrong, space probes can simply be abandoned in space but we cannot do this for people. So space probes allow scientists to study the universe, without the risk of losing people to this study.

Using the concepts of mass movement, we got that it isn't always easy to classify a mass movement event because mass movements often involve combinations of different types of movement.
Mass movement or mass wasting is the process in which rocks, stones, debris or the sediments are forced downward the hill or slope with respect to the action of the gravity. Mass movement does not always leads to landslides as it depends upon the density of moving the material going down the slope. The heavier and the denser the material, the more profound will be the affect resulting in the landslide but lighter material cannot cause landslide.

How does a light ray change it's path from rarer to denser medium and from denser to rarer medium
Answer:
When a light ray is incident obliquely from one transparent medium to another, its path undergoes a deviation which is called refraction. This is because light travels at a different speed in different media. The speed of light in the denser medium is less than the speed of light in a rarer medium.

Under the appropriate circumstances, sunlight entering the sea may penetrate roughly 1,000 meters into the ocean, although there is rarely much light beyond 200 meters.
Can light that is visible permeate water?Image showing the depth to which visible light may travel in the ocean
Water absorbs more than 50% of the energy of visible light within the first 10 meters. Only approximately 1% of visible light—mostly in the blue range—reaches a depth of 100 m, even in crystal-clear tropical water. The progressive reduction in light intensity that occurs when it passes through a substance is known as attenuation.

Groundwater is groundwater found in cracks and crevices in soil, sand, and rocks. It is stored and slowly moves through formations of soil, sand, and rock called aquifers.
It's pretty hard to imagine how much water is stored underground, but try it. The Ogallala Aquifer, which occupies most of the Midwest and South, holds more water than all the Great Lakes combined.Another advantage is that the water in aquifers is usually very clean to begin with, so cleaning is easy. Usually not contaminated with viruses, sludge, chemicals, etc.However, there is a problem and it is entirely our fault.

The intrusive and extrusive, felsic igneous rocks are Granite and rhyolite.
Extrusive and intrusive igneous rocks are divided into these two main categories. Lava, which is magma that has surfaced from beneath the Earth, is what gives rise to extrusive rocks. Intrusive rocks are created when magma cools and solidifies within the earth's crust.
When lava cools down inside the earth's crust, granite is created. It is a rock made of igneous intrusion. It is referred to as coarse-grained because the crystals are big. Granite and rhyolite have a tight relationship. Granite differs from it because its crystals are significantly finer. Because the crystals are so minute, they cannot be seen with the human eye. Rhyolite forms when lava cools down on or near the earth's surface, unlike granite. Extrusive igneous rock describes it. Rapid cooling causes it to develop, giving it a glassy look.

When individual water molecules escape as gas from liquid water, the process is called Evaporation. when water vapor molecules in the air bind together to form liquid water droplets, the process is called Condensation.
A liquid turns into a gas through evaporation. The forces of attraction between molecules cannot stop them from drifting away when a liquid is sufficiently heated or when the pressure on the liquid is sufficiently reduced. As a result, the liquid evaporates into a gas.
The transition from a vapor to a condensed form is known as condensation (solid or liquid).
The forces of attraction between molecules in a gas prevent the molecules from drifting apart when the gas is sufficiently cooled or, in many situations, when the pressure on the gas is increased sufficiently. As a result, the gas condenses into a liquid or a solid.
