How has rock changed over time?

Answer 1

This is not extremely clear. Uluru and the nearby Kata Tjuta rocks are ends of a sandstone bed that was pushed up through softer overlying soils. Beginning about 30,000 years ago, the desert sand dunes around these harder rocks began to be blown away, exposing and oxidizing the sandstone (the material is normally gray). This uncovering is an extremely slow process, as is the erosion of the sandstone itself. Depending upon climate conditions, Uluru could become less prominent as eroded material builds up in the land around the periphery.

Water erosion has created channels and caves that become more pronounced over time, creating the shadowed edges. The parallel ridges deepen because they represent softer layers of the rock that erode more quickly.

Answer 2

Yes, rocks change over time. A rock at earth's surface can be broken down via mechanical or chemical weathering means. A rock under earth's surface can be 'metamorphosed' and become a metamorphic rock.

Answer 3

Rocks can be changed by several ways. They can be changed with heat, pressure, and water. Water would smooth the stone, pressure could crack the stone, and heat will melt certain types of rock materials.

Answer 4

Rock is weathered, eroded, and is a continuous part of the rock cycle, where melting, metamorphism, and lithification is constantly occurring.

Answer 5

Rocks change over time either by heat or climate change and pressure to it.
