Why is gold in California but not Illinois?
California has more earthquakes and the type of rock where gold is. In Illinois, we have mostly sedimentary rock so we don't have gold deposits.
What happened when mesopotamia got floods?
The floods in mesopotamia were common and irregular, but the mesopotanians dealt with that by living on high banks of rock near the rivers tigress and Euphrate. When the river flooded, the water would go through the banks, not over them, and the rocks would filter out debris. The debris free and nutrient rich water would then water the crops in the fields.
Where was clay invented and is it biodegradable?
Clay was never invented but it was discovered that you dampen it, sculpt it and finally bake it somewhere on the banks of the river Nile. It's not biodegradable as it is actually a kind of rock. It'll turn to dust eventually but only at the same speed a plastic bag will turn into gasses
How did the Harappans control the Indus River?
Posted: I actually have no idea.but if I were to guess they used leves Improved Answer: Wow, leafs? Like that can control a river. Simple, a dam. Made of what? Well, molted rock. Kind of like dams now. Leafs would float away in the river, unless they make it hard as rock...

When water from a river carries sediment or tiny pieces of sand rock or soil it leaves some of the sediment along the banks of the riverthis process is called?
Deposition
What kind of river has a wide flat flood plain and many bends where it deposits rock and soil?
an old river
What is river weathering?
River weathering is the erosion or breakdown of rock and sediment along the banks and bed of a river due to the movement of water. This process occurs as the flowing water carries loose particles and debris, gradually wearing down the riverbanks and bed over time.
What is Large rock placed along a river bank called?
riprap
What is Gold often found in?
Gold is often found in quartz veins or along with other minerals such as pyrite or chalcopyrite in gold-bearing ore deposits. It can also be found in placer deposits, where the gold has been eroded from its original source and concentrated in river beds or sediment.
A rock formed by deposits of shell fragments?
A rock formed from deposits of shell fragment is Limestone.
A river deposits layers of minerals and other rocks at its mouth. Over time, what kind of rock is formed by the deposits?
Over millions of years, layers of sediment may build up and harden into sedimentary rock. Some of the many forms of sedimentary rock include sandstone, rock salt, and coal. Sandstone forms as sand hardens.
Describe the two major processes by which a river changes the land?
Deposition and erosion are two major processes by which a river changes the land. Erosion is the combination of weathering and deposition in which the water loosens and moves the land to another place.
Why is there sand at the bottom of many river beds?
The abrasion and attrition combined with hydraulic action on the river bed and the river banks erode away the underlying rock which results in small grains of rock we call sand. Depending on the speed of the river and the size of the particles, the sand will be deposited by the river at different stages (usually though it is found near the mouth of the river).
What are flat deposits of rock?
moraines
What are fine bits of rock and soil deposited on land by a river?
Sediments, such as sand, silt, and clay, are fine bits of rock and soil that are deposited on land by a river. These sediments are carried by the river's current and then settle on the river banks and floodplains when the water slows down. Over time, these sediments contribute to the formation of fertile soil and landforms in river valleys.
