Identify the relationships between Figure 2, Figure 3, and Figure 4. Drag and drop answers into the correct boxes. Not all answers will be used and some answers maybe used more than once.
The environmental change that occurred was due to the enactment of pollution-control laws. These laws significantly reduced the amount of smoke being released into the environment by some industries. Based on the data in Table 1, during which decade were these laws most likely first enacted?
Which statement correctly answers the question of whether electrical plants that use wind power instead of fossil fuels would maximize power production and minimize GHG emissions?
Identify the location in Figure 2 that best represents the boundary between plates C and D in figure 1
Based on the data, which statement best describes the relationship causing the decreased biomass of the coral reef species in the hydrosphere?
Which question is best addressed by analyzing the data?
Which statements are best supported by the data? Select two of the six statements.
The ice sheets reflect energy from sunlight back into space and allow the Earth to stay cooler. If the ice sheets melt, the amount of energy reflected will change, and thus the temperature of the Earth can change. Based on the data, complete the model to show how a change in the ice sheets leads to changes in other Earth systems.

Based on the estimates of total grass available in the study areas and average grass consumption of an individual bison, which study areas could support a herd of 2,000 bison over the winter?
Scientists plan to introduce a 100-bison herd into a potential habitat area. Which estimate for how much grass all of the juvenile bison in the herd will eat over a period of 30 days is supported by Table 2?
A single hard disk drive can contain all the information from many libraries. When putting the information onto the disk, the disk does not change in size or composition. Hard disk drives were first introduced in 1954 and remained a dominant technology for over 50 years. An electromagnetic wave is generated when the direction of current is repeatedly reversed. This wave creates an alternating magnetic field. Hard disk drives use a part called a write head to store information as bits. When current goes through the write head, it becomes magnetic, which magnetizes the grains. This magnetic interaction allows information to be stored in the magnetized grains of the disk as either a “0” or a “1,” with each 0 or 1 being considered a single bit. This system of using zeros and ones to store information is known as binary code. Bits are shown as downward- or upward-pointing arrows in Figure 1.
What is most important to the process of storing information on a hard disk drive? Select two of the five statements.
How many bits are required to store an image of 1 MB?
The letter "Z" is written as "01011010" in binary code. Identify the correct combination of signs on the current meter to write the letter "Z".
Select all of the correct answers.
Which capital letter was recovered?
Each capital English letter is stored by a sequence of magnetic interactions between the write head and the magnetic grains, as shown in the table. A bit string is obtained by writing bits 1-8 from left to right.
Construct an explanation about how wave interactions store information on a hard disk drive. Support your answer with evidence from the information in Figure 1.
Use an English letter from Table 3 to construct an explanation about how the sequence of the magnetic interactions between the write head and the magnetic grains are used to store information. Support your answer with evidence from the information in Figure 1.
Make a claim about:
• the type of magnetic interaction that is produced when a current is applied to the write head;
• why this magnetic interaction is produced, and
• the bit that results from this interaction.
Support your answer with evidence from information in Figure 1.
