Ques: Answer the following question given this paragraph: Descriptive statistics and graphs help organize data so patterns and trends are more apparent. Descriptive statistics include the mean and range. Types of graphs include bar, circle, and line graphs. Q: Bar, circle, and line are all types of what? Choices: - theories - maps - algorithms - graphs A:
Ans: graphs

Ques: Answer the following question given this paragraph: Mountain streams may erode waterfalls. A waterfall forms where a stream flows from an area of harder to softer rock ( Figure below ). The water erodes the softer rock faster than the harder rock. This causes the stream bed to drop down, like a step. This creates a waterfall. As erosion continues, the waterfall gradually moves upstream. Q: What process is involved in the formation of a waterfall, when a stream flows from an area of harder to softer rock? Choices: - calcification - migration - evaporation - erosion A:
Ans: erosion

Ques: Answer the following question given this paragraph: We are lucky to have an atmosphere on Earth. The atmosphere supports life, and is also needed for the water cycle and weather. The gases of the atmosphere even allow us to hear. Q: What supports life, and is also needed for the water cycle and weather? Choices: - fossil fuels - oxygen - greenhouse gas - atmosphere A:
Ans: atmosphere

Ques: Answer the following question given this paragraph: one degree Fahrenheit. Only 100 Celsius degrees span the same range as 180 Fahrenheit degrees, thus one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale 180 / 100 = 9 / 5. The Kelvin scale is the temperature scale that is commonly used in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points of water are 273.15 K and 373.15 K, respectively. Thus, the magnitude of temperature differences is the same in units of kelvins and degrees Celsius. Unlike other temperature scales, the Kelvin scale is an absolute scale. It is used extensively in scientific work because a number of physical quantities, such as the volume of an ideal gas, are directly related to absolute temperature. The kelvin is the SI unit used in scientific work. Q: Which temperature scale is commonly used in science? Choices: - ph scale - celsius - centigrade - kelvin scale A:
Ans:
kelvin scale
