Wave Rock in Hyden, Australia (32.4438° S, 118.8975° E) is a big rock in the shape of a wave. It used to be a big and long iceberg on top of bedrock. This became a long hill or plateau made of soil and granite, but over time wind eroded the granite away into the wave-like shape. I believe that wave rock was created specifically by water erosion and weathering. Also, the smoothness of the structure is made by wind abrasion. I think in the future Wave Rock will be way different than it is right now. It might become two different hills. This book will explain in detail about the life of Wave Rock.

It took thousands to millions of years for Wave Rock to form in Australia. Before Wave Rock was created, there was a big iceberg which was on top of bedrock. When the ice melted due to the sun and at the end of the ice age, the bedrock in the ground was exposed to concentrated chemicals. These chemicals interacted with the bedrock and changed it. The chemicals would change the bedrock to granite through a chemical change. During this process, the granite got mixed with a little bit of soil and this influenced the appearance of Wave Rock. After this, I think there was a very small convergent plate boundary (where two tectonic plates collide) which forced the granite and soil to move upward which made a long hill/ plateau which was about 49 feet tall and 360 feet long.

The plateau made by the granite and soil/ convergent plate boundary started to interact with its surroundings (rain, wind, and chemicals) and started to slowly erode into a wave shape. Raindrops would do water erosion to the plateau and also some of the leftover chemicals started to do chemical weathering to the rock. Also, mechanical weathering by wind would start to carve the rock into a wave-like shape. The formation that was formed was very bumpy and rough. All of this was powered by the Sun because it runs the water cycle and it is in charge of the weather. Also, some of the water left from the ice age/ iceberg and the rain started to create small ponds.

Geological processes like water erosion, chemical weathering, and mechanical weathering made Wave Rock very bumpy and rough. Over time these processes kept interfering with the formation but at the same time, wind abrasion started to intervene with Wave Rock too. Wind abrasion happens when the wind containing dust and sand go over a landform and smoothes it out. Wave rock got abraded by wind and it got smoothed out a lot. This geological process keeps interfering with Wave Rock so no jagged edges are formed.

In the future (after about more than a thousand years), I think that Wave Rock will look way different than it looks now. I think the geological processes like water erosion, wind erosion, wind abrasion, mechanical weathering, and chemical weathering will keep interfering with Wave Rock and will increase the wave-like shape. I believe in the future that Wake Rock would become very thin at the edge (curve part) and then the top part will become weaker and form cracks. When it rains, water will get in these cracks and freeze and make the cracks bigger. This is the start of ice wedging and the ice creates the room for more ice and plants to grow in the crack. These two types of mechanical weathering will make the top of Wave Rock fall off. If the geological processes keep interacting, I think it will make two hills which will be smooth. There will be one big and one small hill.

That is why you should visit Wave Rock now because later it may not look like a wave anymore.
