B. Tú hablaste con la maestra.
C. Tú usaste un huso.
D. Tú vas al parque.
Answer (2)
Density increases as depth increases.
Thickness does not consistently increase or decrease.
The correct statement is: As depth increases, the density of the layers increases.
The thickness of the layers does not consistently increase or decrease as depth increases.
Explanation
Understanding the Problem We are given a table with data about the Earth's layers, including their thickness and density. We need to determine how the density and thickness change as depth increases.
Analyzing Density Let's analyze the density. The density at the top of each layer is: Crust (2.2), Upper mantle (3.4), Lower mantle (4.4), Outer core (9.9), Inner core (12.8). The density at the bottom of each layer is: Crust (2.9), Upper mantle (4.4), Lower mantle (5.6), Outer core (12.2), Inner core (13.1). In both cases, the density increases as we go deeper into the Earth.
Analyzing Thickness Now let's analyze the thickness. The thickness of each layer is: Crust (30), Upper mantle (720), Lower mantle (2171), Outer core (2259), Inner core (1221). The thickness increases from the Crust to the Outer core, but then decreases at the Inner core. Therefore, the thickness does not consistently increase or decrease.
Conclusion Based on our analysis, the density of the layers increases as depth increases, while the thickness does not consistently increase or decrease.
Examples
Understanding the Earth's structure helps us learn about geological processes like earthquakes and volcanic eruptions. The increasing density with depth is due to the compression of materials under immense pressure. This concept is also applicable in material science, where understanding density variations in different materials is crucial for designing structures and predicting their behavior under stress.
The regular verb in the imperfect tense is found in option A, 'Tú leías hechizos,' which means 'You were reading spells.' The verbs in the other options are either in the preterite or present tense, not the imperfect. The correct option captures an ongoing action in the past.
