There was an American expedition that has documented the Namche Barwa Gorge in eastern Tibet as the world's largest and deepest canyon in October 1993. Although Peru's Colca Canyon was officially declared the earth's deepest at 10,500 feet in 1981, the Namche Barwa Gorge in eastern Tibet has been rumored to exceed this for quite some time. |
Tania's raised her hand. She hoped it wasn't too late having just remembered the answer to the question. "I believe the world's deepest canyon is the Yarlung Tsang Po in Tibet," she answered. |

7. Oldest confirmed impact on Earth? |
The Barringer Crater is the first crater to be proven the result of an impact |
Tori rised her hand and said "South Africa`s Barberton greenstone belt and Australia`s Pilbara block." |
"I don't have a place, but it was said a rock hit the earth 3.5 billion years ago, with pieces found in Africa and Austalia" Zekk said with very little confidence. |
Zekk was closer... Hint: It is somewhere in canada... just a date of how old they are will be enough... |
Mistastin Lake, Newfoundland and Labrador, Canada |
"On August 23, 2002, two scientists announced their discovery of a 3.47 billion year old meteorite that struck earth. The diameter is around 12 miles wide. All traces of a crater have been eroded away." |
Raising her hand, "I will guess it's the Sudbury Impact, in Ontario, Canada. It had a diameter of 250.00 km and fell some time 1850 ± 3 *Ma (1.85 billion years ago)." |
The Sudbury Basin - 1.8 billion years ago |

Someone already had it... ^^ Ok this question that has something to do with Canada. 8. Oldest volcanic rocks on earth? |
"In Quebec, Canada, it is said that they found rocks that are 3.825 billion years old," Roma replied. |
Jamie said, "Canadian geologists say they've found Earth's oldest volcanic and sedimentary rocks in northern Quebec. The estimated 3.825-billion-year-old rocks could help scientists to understand the first quarter of the planet's history." |
Kali raised her hand and said full of uncertainty, "The oldest volcanic rocks on Eath are about 3.825 billion years old. They're found in the Inukjuak area in Quebec, Canada." |
Bailey raised her hand. "I believe they are the rocks found in Quebec that date back approximately four billion years." |

Anila tapped her finger to her chin, thinking. It came to her, at the same time as Roma, so she kept quiet. |

9. Largest geological feature discovered from space? |
The Richat Structure in the Sahara Desert? |
The geological features in the Cydonia Region are quite interesting. |
I'm not sure what you mean by geological feature >_< so... *raise hand* "The maximum deviations in the shape of the earth is the highest point on it, Mount Everest." |
