13: Based on the geologic diagram below, which of the following statements is not true?


A. The slate layer is older than the basaltic intrusion.
B. The limestone is not the oldest layer portrayed.
C. Basalt is an igneous rock.
D. The sandstone layer is older than the basalt.
A. The slate layer is older than the basaltic intrusion.
A. According to the Law of Superposition, all other factors being accounted for, the most recent (youngest) geologic layers are on the top. Since the slate layer is closest to the surface, it is the youngest.

14: Which of the following is the result of the angle of tilt that the Earth has on its axis?

A. day and night
B. summer and winter
C. continental drift
D. different stars visible in Northern and Southern hemispheres
B. summer and winter
B. Day and night are the results of the rotation of the earth. Continental drift is often offered as evidence of plate tectonics. While the variable star field may be affected by planetary tilt, the position of the observer relative to the star field is also a major factor. The seasons, choice B, are the result of the directness of the Sun's rays hitting Earth's surface. The primary factor controlling directness of the rays of the Sun is planetary tilt.

15: An extinct volcano has steep sides. Rock samples from the immediate area contain both basaltic and granitic rock samples. Excavation of the area reveals alternating layers of ash and lava flows. The volcano was most likely of which volcanic variety?

A. cinder cone
B. shield cone
C. composite cone
D. You cannot determine volcanic type from the data provided.
C. composite cone
C. The hallmark of a composite cone composition is the mixture of cinder cone characteristics (granitic debris, very steep cone profile, and explosive eruptions) with shield cone characteristics (large footprint with gently sloping sides, basaltic debris, and lava flows).

16: When air masses meet, why does warm air rise over cooler air, often causing rain?

A. Warm air is less dense than cooler air.
B. Warm air is denser than cooler air.
C. Cooling air can hold less water vapor than warmer air.
D. Cooler air is very volatile.
C. Cooling air can hold less water vapor than warmer air.
C. Choice A is a true statement but it does not explain rain, only the motion of the fronts. The motion of the warmer air over cooler air is due to differing densities, but it is the drop in temperature due to increased elevation and contact with cooler air (among other things) that causes the rain. As air cools, its capacity to hold water vapor decreases. As the saturation point is reached, excess water vapor condenses on particles in the air and eventually can fall as rain.

B. meiosis.
C. cytokinesis.
D. cell division.
