What else can I help you with?
Which substance is most resistance to weathering rock or sand?
Rock is more resistant to weathering than sand because of its larger particle size and greater cohesion between particles. Sand is easily transported by wind and water, leading to faster erosion and weathering.
Sand is made by?
The weathering and erosion of rock.
What do the agents of weathering do?
Erode rock into sand.
How are pedestal rock formed?
Pedestal rocks are formed through a process called differential weathering. This occurs when softer rock surrounding a harder, more resistant rock erodes more quickly, leaving the harder rock standing on a pedestal-like structure. Over time, the pedestal rock may be further shaped by weathering and erosion.
How are sand and mud and pebbles similar?
All are a product of rock weathering.
What is loose grains of rock material called?
sand
Why is quartz sand a better tool of wind and water erosion than gypsum sand or calcite sand?
Quartz sand is more resistant to weathering and erosion compared to gypsum sand or calcite sand because quartz is harder and less soluble in water. Gypsum sand is softer and easily dissolves in water, while calcite sand is more susceptible to chemical weathering. As a result, quartz sand is able to withstand wind and water erosion more effectively over time.
How does sand cause weathering?
Sand can cause weathering through a process called abrasion, where wind or water transports sand particles that then physically wear down rocks through friction. As sand particles rub against rock surfaces, they can slowly break down the rock into smaller pieces, gradually leading to weathering and erosion.
What do you think will happen if there is continued weathering?
Eventually, rock wears away into sand.
What causes mechanical weathering by blowing sand against exposed rock?
wind
What causes mechanical weathering to blow sand against exposed rock?
Wind
How does schist become sand?
Weathering like wind, water, or plants break down the rock turning it to sand!
