Cráter

The video explains how craters on the moon and Earth are primarily formed by meteorite impacts, which leave distinct features like crater rims and ejected matter. It also covers other processes that can create craters, such as explosive volcanic eruptions and subsidence, including those caused by underground nuclear tests.

What is the primary cause of craters on the moon and Earth?

• Volcanic eruptions

• Meteorite impacts

• Tectonic activity

• Erosion

What characteristic feature is left by meteorite impacts?

• Lava flows

• Crater rim and ejected matter

• Mountain ranges

• River valleys

Besides meteorite impacts, what is another natural process that can form craters?

• Tsunamis

• Volcanic eruptions

• Glacial movement

• Wind erosion

What is an example of human activity that can cause subsidence leading to crater formation?

• Deforestation

• Underground nuclear explosions

• Mining

• Urban development

Which of the following is NOT a cause of crater formation mentioned in the video?

• Tidal forces

• Meteorite impacts

• Volcanic eruptions

• Subsidence
