A. The Heated Soil Scenario Walter placed 240 grams of sand (S), potting soil (P), and a mixture of sand and soil (M) into

separate containers. In each of the containers he placed a thermometer so that the bulb was

2.5 cm below the surface. He placed all 9 containers under identical heat lamps for an hour.

After heating the containers in three separate trials, the temperatures were (all are in degrees

centigrade):

S: 28, 27, 26

P:33, 29, 31

M: 29, 29, 22.5

answer; ///the correct answer to the above question is (

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
