Question

with regard to ancient climates, wegener's continental drift hypothesis states that 300 million years ago, ___________________________.

Answer 1

Wegener's continental drift hypothesis suggests that about 300 million years ago, the continents were united into a supercontinent called Pangaea, which later broke apart and drifted apart, altering climates globally.

Step-by-step explanation:

With regard to ancient climates, Wegener's continental drift hypothesis states that 300 million years ago, all the continents were once joined together, forming a giant supercontinent known as Pangaea. This supercontinent later broke apart, and the continents drifted to their current positions. The hypothesis explains that this drift caused significant changes in the climate, with some lands moving closer to the poles and others towards the equator. Additionally, the drift was accompanied by intense volcanic activity and changed the climates worldwide.

Answer 2

Wegener hypothesized that 300 million years ago, continents were merged into a single supercontinent named Pangaea, which later drifted apart, influencing Earth's climate and geology.

Step-by-step explanation:

With regard to ancient climates, Wegener's continental drift hypothesis states that 300 million years ago, all continents were joined together forming a supercontinent called Pangaea. This immense landmass started to break apart, leading to the configuration of continents as we know them today.

The theory also suggests that this breakup of Pangaea resulted in the drifting of continents, subsequently altering Earth's climate and causing massive geological changes like volcanic activities. Wegener's hypothesis was initially met with resistance as he could not provide a mechanism for the drift, but it laid the groundwork for the modern understanding of plate tectonics.
