geological stages

Geological stages:

The Earth’s surface is constantly changing. During these changes and

evolution, we can identify different geological stages.

• TRUE

• FALSE

The different geological stages in order are:

• • Precambrian time (4500 to 542 mya).

  • Palaeozoic Era (542 to 250 mya).

  • Mesozoic Era (250 to 65 mya).

  • Cenozoic Era (66 mya)

• •Palaeozoic Era (4500 to 542 mya).

  • Precambrian time (542 to 250 mya).

  • Mesozoic Era (250 to 65 mya).

  • Cenozoic Era (66 mya)

• • Precambrian time (4500 to 542 mya).

  • Mesozoic Era(542 to 250 mya).

  • Palaeozoic Era(250 to 65 mya).

  • Cenozoic Era (66 mya)

Choose the correct geological stage: in the _________ New mountain

ranges composed of hard materials formed.

Choose the correct geological stage: The ____ is divided into three Periods: Paleogene, Neogene and Quaternary

• Precambrian time

• Palaeozoic Era

• Mesozoic Era

• Cenozoic Era

Choose the correct geological stage:

During the________The first

mountain ranges formed. Erosion destroyed them

• Precambrian time

• Palaeozoic Era

• Mesozoic Era

• Cenozoic Era

Choose the correct geological stage:

During the ________The sea covered dry

land and there was intense sedimentation.

• Precambrian time

• Palaeozoic Era

• Mesozoic Era

• Cenozoic Era

___________ (2.58 mya to present). There

were periods of glaciation when ice covered a

large part of the continents. This caused intense

erosion in mountain areas.

• Paleogene Period

• Neogene Period

• Quaternary Period

_______ (66 to 23 mya). Tectonic plate

movement and alpine orogeny occurred. This

formed young mountain ranges, such as the Alps.

• Paleogene Period

• Neogene Period

• Quaternary Period

______(23 to 2.58 mya). Continental

movements occured, most importantly between

North and South America.

• Paleogene Period

• Neogene Period

• Quaternary Period
