When we consider changes in the shape of land, there are a number of things that can cause it. Plate tectonics, the shifting of the large "pieces" or tectonic plates that cover the surface of the earth, is a major cause of massive changes in the shape of land. The process is slow, but it moves whole continents around. Abrupt changes as stress between plates is relieved results in earthquakes. Also recall that a tsunami, a tidal wave, can be generated by earthquakes, and the massive movement of water can quickly change the shape of areas of land where it comes ashore. There are other forces that can change the shape of land, too.
Volcanic action can cause changes in the shape of land. The big island of Hawaii is increasing in area because of vulcanism. Volcanic action can be something that happens over weeks, months, years or decades. It can also happen in hours as was demonstrated by Krakatoa and other massive volcanic blasts.
Weathering by wind and water erode the land and change its shape. Uplift as a result of tectonic action builds whole chains of mountains, and weathering wears them down to small hills, all over many thousands or millions of years. A big river may move countless tons of material down its length to deposit it near its mouth.
Glaciers made of ice carve valleys out of the Earth's surface and have contributed to the creation of some of the most spectacular scenery on our planet. Also the weight of the ice sheets was large enough to depress the surface of the Earth (making the lithosphere sink further into the asthenosphere on which it floats). Once the ice sheets covering the Earth's surface melted (particularly in the northern hemisphere) the surface had to readjust and has started to rebound. This means that in places like the UK, Scotland and Northern England is actually rising and Southern England is sinking! This process is known technically as post glacial isostatic readjustment.
Once in a while a big rock from space will slam into the earth and change the shape of the land. The larger the rock, the more it can do to alter the terrain. Man can also change the shape of land. We dig big holes in the ground to recover minerals, and these holes can be seen from space. We also move material into the ocean to extend land or make islands. The new airport in Hong Kong is situated on land "created" by adding material to small existing islands, just to cite a single example.
Elasticity is the property that allows a material to change shape when a force is applied and then return to its original shape once the force is removed.
Yes, a force can change the shape or size of an object by deforming it. External forces applied to an object can stretch, compress, bend, or break it depending on the magnitude and direction of the force applied.
what are three ways that people have changed the land in our country
solids have a regular geometrical shape . they have a tendency to maintain their shape when subjected to outside force. solids may break under force but it is difficult to change their shape.
Two factors that affect the shape of land are erosion, which wears away land over time through processes like wind and water, and tectonic forces, such as plate movement and volcanic activity, which can cause land to shift and change in elevation.
If a force causes an object to change shape, it means that the force is causing deformation in the object by altering its structure or appearance. This change in shape can be temporary or permanent, depending on the magnitude and nature of the force applied.
Yes, a force applied to an object can deform its shape by stretching, bending, compressing, or twisting it. This change in shape is often temporary and depends on the magnitude and direction of the force applied.
Solids can only change their shape by force, as when broken or cut.

You are probably looking for "Deformation Force".
a force is something that you apply to an object- it can move-change shape-change direction-slow it down-make it faster
Force is an external effort that makes something move, change direction, or change shape.

Mechanical change
People shape the land by laying out fields
water erosion's shape the land into weird shapes :)
A force can cause the object to accelerate, change its shape, or change its direction of motion.
