That would be "sedimentary rock". Sedimentary rock is formed from the accumulation and compression of sediments, including fragments of igneous rock that have been weathered and eroded.
What did the Earths average surface temperature do during the twentieth century?
The Earth's average surface temperature increased during the twentieth century, with a significant portion of this increase occurring in the latter half of the century. This period of warming has been attributed to human activities, particularly the burning of fossil fuels that release greenhouse gases into the atmosphere.
Which of these extraterrestrial bodies do scientists think brought water to Earths surface?
Scientists believe that comets and asteroids may have brought water to Earth's surface. These bodies contain significant amounts of water ice that could have been delivered to Earth through impacts during the early formation of the solar system.

The Earth's surface has changed significantly over time due to processes such as plate tectonics, erosion, and volcanic activity. Continents have shifted positions, mountains have formed and eroded, and oceans have expanded and contracted. These changes have been ongoing for billions of years and continue to shape the Earth's surface today.

Why is the meteorite ALH84001 so important to in terms of searching life on other planets?
Allan Hills 84001 or ALH84001 is a meteorite that was found in the south pole. It is thought to have originally come from Mars. Around 4 billion years ago, the rock was thought to have been ejected from the Martian surface by a large impact. The rock was then thought to have remained in space, until it came into contact with Earth around 13,000 years ago. It is special as it is the only known martian rock to have been ejected from the martian surface during a time when there was thought to be liquid water on the planets surface, essential for life. On examination of the rock, scientists saw `worm like` micro fossils, thinking that they were the remains of early martian life. These features have now been generally dismissed as early martian life forms, but the meteorite remains a very important find.
