Describe how sound waves travel through a solid, liquid, and gas. Why does it move differently through these different mediums?

Answers

Answer:

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.

Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory? A) It was not published until his death. B) It was not understood by scientific world. C) It lacked sufficient evidence and explanation. D) It lacked practical examples in supporting theory.

Other Causes of Extinction

In addition to habitat destruction, other human-caused problems are also threatening many species. These include issues associated with climate change, pollution, and over-population.

Habitat Destruction

Your habitat can be altered, and you can easily adapt. Most people live in a few different places and go to a number of different schools throughout their life. But a plant or animal may not be able to adapt to a changed habitat.

Humans often destroy the habitats of other organisms. Habitat destruction can cause the extinction of species.

Extinction is the complete disappearance of a species. Once a species is extinct, it can never recover.

Invasive Species

As we have learned earlier in the unit, invasive or non-native species can also change an ecosystem.

When invasive species enter an ecosystem they change that ecosystem's dynamic and cause a disruption to the flow.

Climax Community

A climax community is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem, and will remain stable unless a disaster strikes.

Human Activity

It's important to note that human activity has the greatest impact on the amount and quality of wildlife habitat in many areas of the world. Wildlife habitat can be destroyed or its quality diminished as a result of urban growth, agricultural practices, pollution, or habitat destruction.

People can also have a positive impact on wildlife populations through improvement and protection of habitat or ecosystems. Planting trees and shrubs and providing sources of food and water in individual yards is one way people can help wildlife.

Out of all the planets in the solar system, Earth is the only planet that scientists can study in detail. Atmospheric scientists can measure minute by minute atmospheric conditions (weather) from ground level to the “edge of space” by use of surface instruments and space vehicles. Geologists not only can detail surface features and how they change over time, but also can deduce Earth's structure to its very center. The division of Earth's interior into a core, mantle, and crust structure sets the context for how we study the other similar planets.

Why do people mix up weather and climate?

Answers

Answer:

The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.

Giraffes have very soft skin and can’t tolerate the cold and basically need warmth to live.

How is an image formed by a plane mirror?
A) Light bounces off of the mirror and then appears to come from in front of the mirror.
B) Light passes through the mirror and then appears to come from behind the mirror.
C) Light passes through the mirror and then appears to come from in front of the mirror.
D) Light bounces off of the mirror and then appears to come from behind the mirror.

Answers

Answer:Light bounces off of the mirror and then appears to come from behind the mirror.

Explanation:Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.

When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.

The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen..
