Weathering
The force that causes rock layers to crumple and fold is mainly tectonic forces, such as compression. When two tectonic plates collide or move toward each other, the rocks in between experience intense pressure, leading to deformation and folding of the rock layers.
Chemical weathering
The force that adds potential energy to a rock until the rock changes is gravity. As the rock is lifted against the force of gravity, potential energy is stored in the rock. Once the rock falls or is released, this potential energy is converted into kinetic energy, causing the rock to change position or state.
No actually it isn't. Breaking a bone is a physical change. Think about it. Are you changing it into a different substance. No you're not, so it's a physical change.
The driving force for the upward movement of warm molten rock in the mantle is primarily buoyancy. As molten rock is less dense than the surrounding solid rock, it rises due to its buoyancy forces. Additionally, convective currents within the mantle, driven by heat from Earth's core, also play a role in the movement of molten rock.
The force that causes rock to change shape is typically pressure due to tectonic forces, which push, pull, or squeeze the rock. This force can deform the rock, leading to changes in its shape over time. Additionally, factors like temperature variations and erosion can also contribute to the changing shape of rocks.
Heat, pressure, weather, gravity, plate tectonics--all play a part in the rock cycle.
When an applied force causes rock to break, it typically results in the formation of cracks or fractures in the rock. These cracks propagate through the rock as the force is applied, eventually leading to the rock breaking into smaller pieces or fragments. The extent of the breakage will depend on factors such as the type of rock, its structure, and the magnitude of the applied force.
The application of heat and / or pressure causes a rock to be transformed into a metamorphic rock.
When an applied force exceeds the rock's strength, it causes the rock to break. The stress from the force surpasses the rock's ability to withstand it, leading to fractures and ultimately the rock splitting or breaking apart. This process is influenced by factors such as the type of rock, its structure, and the direction of the force applied.
The force that causes a rock to roll down the side of a mountain is primarily gravity. Gravity pulls the rock downward toward the center of the Earth, and when the rock is on an incline, this force causes it to accelerate down the slope. Additionally, friction between the rock and the surface may influence its movement, but gravity is the dominant force driving it downward.
The stress force that causes a mass of rock to pull or twist in opposite directions is called tension. Shearing is the stress force that causes a mass of rock to pull or twist in opposite directions.
Shape of rock also changes because of stress. It causes the rock to change its shape. When a lot of pressure applies it causes the rock to change its shape.
Mechanical change
When an applied force causes rocks to break, the stress exceeds the rock's strength, leading to the rock fracturing. This can generate cracks, fractures, or fault lines in the rock. The type of breakage (e.g., sheer, tensional, or compressional) depends on the direction of the applied force relative to the rock's natural weaknesses.
Gravity
The force that acts on a rock to change it is usually weathering and erosion. Weathering breaks down the rock into smaller pieces, while erosion transports these pieces to a new location, changing the shape and size of the original rock.
