Integrated Physical Sciences - C165 Exam Questions and Answers 100% Correct

Integrated Physical Sciences - C165 Exam Questions and Answers 100% Correct is the study of atoms and molecules, their structures, and their interactions to form new substances. - Answer - Chemistry Chemistry studies atoms and molecules and how they interact to form new substances. Which field of physical science MOST directly explains how the motion of the continents over 100 million years led to mountains and volcanoes in some places above land, and deep ocean trenches in other places beneath the ocean surface? physics chemistry Earth science - Answer - Earth Science Earth's features and the processes that change them are the subject matter of Earth science. Satellites orbiting Earth scan the light reflected from below, and the data can then be analyzed to get information about the objects that reflected the light. This technology is called "remote sensing." For example, they can even distinguish between astro turf in a football field and real grass on the ground below, even though these look the same to the human eye. Which field of science would MOST directly devise ways to detect and analyze reflected light obtained by remote sensing? physics life science chemistry Earth science - Answer - Physics Detecting and analyzing reflected light is dealt with by physics. Which type of scientific study is BEST suited for collecting data that will be used to analyze statistical information about the kinds of meanders, or turns, in the path of rivers such as the one shown in the photograph below? field study laboratory study controlled experiment The picture is an overview of a winding river - Answer - Field Study The researchers would have to travel to actual rivers to gather their data. Which of these fields relies the MOST on laboratory studies? Earth science chemistry - Answer - Chemistry Most of the research in chemistry is conducted through controlled laboratory experiments. Many species of fish contain a swim bladder within their body that is filled with gas and helps the fish to control and maintain their depth below the water. What two fields of science MOST directly explain the operation and evolution of the swim bladder o f fish? physics and chemistry chemistry and Earth science physics and life science Earth science and life science - Answer - Physics and life science Geckos, like the one shown here, are known for being able to walk on very smooth surfaces, even upside -down. Tiny ridges on the gecko's feet allow it to stick to a smooth glass surface because of weak forces between the atoms in the gecko's foot and the atoms in the glass. Which two fields of physical science would be MOST relevant in investigating how a gecko sticks to glass? Earth science and chemistry physics and chemistry chemistry and biology - Answer - physics and chemistry The weak forces between molecules and the way the electrons move is dealt with mainly by physics. A scientific procedure done in order to test a hypothesis is a(n) - theory law experiment - Answer - Experiment An experiment is a planned procedure done with the goal of verifying or refuting a hypothesis. How does a hypothesis compare with a law? A law and a hypothesis are both supported by little if any evidence. A hypothesis is supported by extensive evidence, but a law is supported by little, if any, evidence. A law and a hypothesis are both tested and supported by extensive evidence. A law is supported by extensive evidence, but a hypothesis has not been tested enough to be supported by extensive evidence yet. - Answer - A law is supported by extensive evidence, but a hypothesis has not been tested enough to be supported by extensive evidence yet. Both laws and hypotheses are supported by extensive evidence. The difference however, is that laws are proven, while a hypothesis are not. Theories help scientists - prove hypotheses explain large amounts of data determine what is true and what is false - Answer - explain large amounts of data Which of the following models can be touched? mathematical conceptual computational physical - Answer - physical The main goal of a physical model is to allow you to touch it or observe it in space. Someone hypothesizes that there are invisible beings living on Earth that cannot be detected by any possible means. What is the BEST reason why the scientific community would be unlikely to plan a scientific investigation to test the hypothesis? Scientists do not like controversy.
