The two primary forces that caused the early Earth's size and structure to change were gravitational forces and volcanic activity. Gravitational forces led to the accretion of material, allowing the Earth to grow in size as dust and gas from the protoplanetary disk coalesced. Volcanic activity contributed to the planet's differentiation, allowing heavier materials to sink and form the core, while lighter materials formed the crust and mantle. Together, these forces played a crucial role in shaping the Earth's initial structure and composition.
Deformation is a change in the shape or size of a material due to stress or strain. It can be caused by external forces such as pressure, tension, or shearing forces acting on the material, leading to a rearrangement of its atomic structure. Deformation can result in a temporary change (elastic deformation) or a permanent change (plastic deformation) in the material.
Velocity change can result in changes in an object's speed and/or direction of motion. This change in velocity can be caused by forces such as acceleration, deceleration, or changes in direction, which can affect the object's kinetic energy and momentum.

A person who studies the relationship between the Earth's physical features and the forces that shape or change them is known as a geomorphologist. Geomorphologists analyze landforms, processes like erosion and sedimentation, and how these elements interact over time. Their work often involves examining the impact of natural forces, such as tectonic activity and climate, on the landscape.
Two words: Tidal Forces.
Water caused the forces to change as it softened the straw and clay ball, making them more susceptible to deformation and displacement.
Dead loads: Permanent static forces acting on a structure due to its own weight, such as concrete slabs or steel beams. Live loads: Temporary dynamic forces that can change in magnitude and location, like people or vehicles moving on a bridge. Wind loads: Forces caused by wind pressure on a structure, which can vary based on wind speed and direction. Seismic loads: Forces generated by earthquakes or ground vibrations that can cause lateral movement in a structure.
Acceleration is caused by a change in an object's velocity over time. This change can result from forces such as gravity, friction, or applied forces. The direction of the force will determine the direction of the acceleration.
The constant interaction between rocks and external forces like weathering, erosion, and tectonic activity can change the Earth's surface. However, the fundamental composition and structure of rocks themselves cannot be changed by external forces other than extreme conditions like high pressure and temperature in the Earth's interior.
A change in an object's motion can be caused by both balanced and unbalanced forces. Balanced forces result in no change in motion, while unbalanced forces cause acceleration or deceleration in the object's motion.
Early Earth's size and structure changed due to accretion of material from the protoplanetary disk, impacts from asteroids and comets, internal heating leading to differentiation into layers, and the release of gases from volcanic activity that contributed to the atmosphere.
When you draw the molecular structure, the structure is in fact symmetrical. When the structure is symmetrical it is non-polar therefore the forces are said to be 'london forces'/ dispersion forces.
Exogenous forces are forces that work above the earths surface and break down landforms. Endogenous forces are forces that work below the earths surface and build up land forms
Earthquakes are internal forces of change caused by tectonic plate movement and stress release along faults within the Earth's crust. They are not considered external forces as they originate from within the Earth.
