The forces of gravity between two objects fall off as the square of the distance between them.If you were three times as far from the center of the Earth as you are now,then the forces of gravity between you and the Earth would be1 / (3^2) = 1/9 of what they are now.Putting it simply, your weight would be 1/9 of what it is down here on the surface.
Yes, that's basically what causes tides. ===================== And the moon. Lets not forget its role.
Since the Earth's crust is a dynamic surface that is controlled by convection in the Earths core, the plates on which the surface lies are moving, called plate tectonics. This tectonic motion produces subduction which recycles and changes the Earths surface resulting in a ever changing and recycled surface, that does not preserve impact craters. Also, erosional and weathering processes erode away the higher parts of craters leaving no clear marking of craters over a long period of time.

Three forces that reshape the Earth are plate tectonics, erosion, and volcanic activity. Plate tectonics cause the movement of continents and the creation of mountains and rift valleys. Erosion shapes the Earth's surface by wearing away landforms through processes like wind, water, and glaciers. Volcanic activity can change the landscape by creating new land through lava flows, ash deposits, and volcanic mountains.
gravity, buoyancy, surface tension.
Yes, there are typically three main forces acting on a pen: gravity pulling it downward, the normal force exerted by the surface it rests on pushing it upward, and the force exerted by your hand when writing or moving it.
The three forces acting on a book could include gravity, which pulls the book downward towards the Earth; the normal force exerted by the surface the book is resting on, which pushes the book upwards to balance gravity; and friction if the book is being pushed or pulled across a surface.
Internal forces: tectonic plate movement, volcanic activity, and earthquakes. External forces: weathering, erosion by water/wind/ice, and impact events (e.g. meteorites).
Gravity, friction, momentum
When a water glider is standing on a still pond, three forces acting on it are gravity, buoyancy, and surface tension. Gravity pulls the water glider downwards towards the center of the Earth. Buoyancy, an upward force exerted by the water, counteracts the force of gravity, helping the water glider float. Surface tension, a cohesive force between water molecules at the surface, also supports the water glider by creating a thin film that resists the object from sinking.
Yes, there are typically three main forces acting on a pen at rest on a table: the gravitational force pulling downward, the normal force pushing upward from the table's surface, and the force of static friction preventing the pen from sliding. In this scenario, the net force is zero, so the pen remains at rest.
