Antworten
-
Refers to the rate of change in temperature with depth in the Earth
-
Increases as you go into the Earth
-
Averages about 5 degrees celcius per km in the upper crust

Identify the False statement. The nuclear theory states that...
Antworten
-
as the universe cooled, atoms and molecules accumulated in patchy clouds of gas called nebulae
-
nebulae condensed and heated to become spinning accretion disks

as density increases due to more gas being crammed into a small space, temperature cools
-
gravity caused the inward collapse of dense gas to form protostars

was inhibited by the presence of radioactive elements because their decay absorbs heat from their surroundings
-
began with heating up component materials within their bodies
-
is the process by which these bodies develop internal layering
