SCIENCE GED PRACTICE

Satellites are widely used in many scientific studies. They allow large areas to be monitored easily. They can measure the spread of an ash plume, such as the one from Eyjafjallajokull’s 2010 eruption, as well as SO2 emissions. In SAR and thermal imaging can monitor large, scarcely populated areas where it would be too expensive to maintain instruments on the ground.

What type of geologist’s research would benefit most from using a satellite as described?

• a mining geologist

• a geochemist

• a mineralogist

• a volcanologist

) What is the most likely reason that the marble reached a higher distance above ground in test #4 than in all of the other tests?

Marble on a String Experiment

• A. The student who released the marble may have pushed the marble toward point D, rather than simply releasing it.

• A. The student who released the marble may have released it from a height lower than 36 cm.

• A. The student who released the marble may have released it too soon.

• The student who released the marble may have waited too long to release the marble.

What is the largest source of freshwater on the Earth?

Distribution of Water on the Earth

If 100,000 people represented all water on the Earth where would they be located?

• atmosphere

• glaciers and snow

• oceans

• rivers and lakes

Which of the following best expresses the approximate change in number of reported measles cases from 2012 to 2014?

Reported Cases of Measles in the United States, 2000 - 2016

• The number of reported cases increased by about 400

• The number of reported cases increased by about 600.

• The number of reported cases decreased by about 200.

• The number of reported cases decreased by about 300

Based on the diagram, choose the set of elements to complete the photosynthesis summary equation:

• CO2; C6H12O2; H2O; O2

• CO2; H2O; C6H12O6; O2

• H2O; C6H12O6; CO2; O2

• H2O; O2; CO2; C6H12O6

Which of the following statements is best supported by the data in the graphs?

Baird Mountain Dall Sheep: Number of Rams vs. Number of Ewes

• A. The average number of ewes is less than the average number of rams.

• A. The average number of ewes is more than double the average number of rams.

• A. The average number of rams is equivalent to the average number of ewes.

• A. The average number of rams is more than double the average number of ewes.

The law of conservation of mass states that matter cannot be created or destroyed. During the course of a reaction, the amount of an element present does NOT change. This means that for a chemical equation to be balanced, the total number of atoms of each element has to be the same on both sides of the equation.

Balance the given equation by choosing the correct coefficient for Cl2.

2 Na + ____ Cl2 → 2NaCl

• 1

• 2

• 3

• 4
