D．by
A.
Air is (1) , and like all matter, it has weight. Weight is the measure of the (2) of gravity (3) matter. If a scale registers 10 kilograms when a stone is placed on it, this means that gravity pulls the stone with that (4) force. (5) , earth’ s gravity pulls on each (6) of gas and dust on the atmosphere. Because our atmosphere is a. vast (7) of air, it has (8) . If it could (9) be compressed and put on a (10) of scales, it would weigh about 5,700,000,000,000,000 (quadrillion) metric tons.
B.
The air pressed down on us and against us (11) all sides. Something (12) a ton of air is pressing against you at this moment. You are not (13) of this because air pressure within your body (14) the pressure of the air outside.
C.
Air pressure is 1. 036 kilograms per square centimeter (14.7 pounds per square inch) at sea (15) . It is greatest there because that is the (16) of the atmosphere. (17) higher altitudes the pressure is (18) . That is why the (19) of highflying planes are pressurized. They are designed to (20) the air pressure our bodies must have.

B.
Scattered around the globe are more than 100 small regions of isolated volcanic activity known to geologists as hot spots. Unlike most of the world’ s volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth’ s surface; on the contrary, many of them lie deep in the interior of a plate. Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The hot spots and their volcanic trails are milestones that mark the passage of the plates.
C.
That the plates are moving is not beyond dispute. Africa and South America, for example, are moving away from earth other as new material is injected into the sea floor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth’ s interior. It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it. Hot spots, anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years.
D.
The significance of hot spots is not confined to their role as a frame of reference. It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe. When a continental plate comes to rest over a hot spot, the material rising from deeper layer creates a broad dome. As the dome grows, it develops seed fissures(cracks); in at least a few cases the continent may break entirely along some of these fissures, so that the hot spot initiates the formation of a new ocean. Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability(inconstancy).
