Gravity

The pull of gravity on Earth is directly related to the mass of the Earth and the distance of an object from the Earth's center. The force of gravity decreases with increasing distance from the Earth's center but increases with greater mass.

When gravity transports material downslope, it is called mass wasting or movement. This natural process involves the downslope movement of rock, soil, and other debris due to the force of gravity. Mass wasting can range from slow and imperceptible movements to rapid events like landslides and rockfalls.

Yes, there is gravity at the center of the Earth, but it cancels out due to the mass pulling equally in all directions. This creates a net zero gravitational pull at that point.

When gravity's downward pull on sediment is greater than the cohesive forces within the sediment, it can cause the sediment to move downslope in a process called mass wasting or sediment erosion. This can lead to various landforms such as landslides, mudflows, or rockfalls.

If we use fossil fuels we can't conserve them, but we should try to use them efficiently, as they can't be replaced and will eventually be used up. Thus drive a 2 litre car instead of a 4 litre or more, 2 litres will take you fast enough. A 6 litre car is just grotesque and totally unnecessary.

In terms of renewable resources, we should aim at replacing what is used up, thus growing more wood to replace what is logged out. In some areas this policy is followed but there are many places where it isn't, and the environment suffers.

The specific gravity of clay can vary depending on its composition and density. On average, the specific gravity of clay ranges from 2.0 to 2.7, with some types of clay having higher or lower values. Specific gravity is a measure of the density of a substance compared to the density of water, with pure water having a specific gravity of 1.0.

Slope and gravity influence mass movement by determining the speed and direction of the movement. A steeper slope increases the force of gravity pulling on the material, making it more likely to move downslope. Higher slopes and stronger gravitational forces can create conditions for rapid mass movements like landslides or rockfalls.

Pluto may be considered small in planet terms, but its still a pretty big rock, and its moon is small enough so that they can have a mutual gravitational attraction, and the moon can be in a stable orbit. Pluto can have gravity on it, anything that's bigger than something else has gravity on it, even an elephant has gravity over a mouse, its just too small of an amount to do anything

The movement of sediment by wind is called aeolian transport, by water is called fluvial transport, and by gravity is called mass wasting or sediment gravity flow. Each process plays a significant role in shaping landforms and transporting sediment across different environments.

The specific gravity of breccia can vary depending on its composition. On average, the specific gravity of breccia is around 2.5 to 2.8. Breccia is a type of rock made up of various fragments cemented together, such as broken pieces of other rocks, which influences its specific gravity.

Yes, mass wasting is the movement of rock, soil, and debris down a slope under the force of gravity. Gravity plays a critical role in causing mass wasting by pulling materials downhill.

This force is called capillary action.

All mass attracts all other mass, thats a fact.

The force due to gravity between the earth and another object, is dependent on their combined mass (earth and object), and the square of the distance between the centres of gravity.

If Earth's gravity was a billion times stronger than a black hole's, everything on Earth would be crushed instantly under the immense gravitational force. The planet itself would collapse into a black hole due to the overwhelming gravity. Life as we know it would cease to exist.

yes but only 1/6th of what we feel on earth

Gravity causes layers of sediment to be horizontal because as sediment deposits, it settles evenly due to gravity pulling the particles downwards. Over time, as more sediment accumulates, the weight of the new layers causes the underlying layers to compact and settle into a horizontal orientation.

The gravitational constant mentioned by Newton was measured at the end of the 18th century by Henry Cavendish (in the Cavendish experiment), using a torsion balance or pendulum designed by Mitchell which measured the force between suspended lead balls, which twisted (or applied torque) to a bar, the magnitude of which is proportional to the force applied. His intent was to detemine the specific gravity of the earth, but his notes indicate a value for G which differs by only about 1% from the value accepted today.

Gravity plays a significant role in the deposition process by influencing how sediment particles are transported and deposited. Gravity causes sediment particles to settle and be deposited in depositional environments based on their size and weight. Heavier particles tend to settle first, while lighter particles may be transported further before they are deposited.

The four ways sediments erode by gravity are creep (gradual downhill movement of soil), slides (sudden movement of large masses of soil downhill), flows (movement of sediment mixed with water downhill), and falls (sediment falling freely due to gravity).

Positive gravity anomalies in geology indicate areas where the density of subsurface material is higher than average. This can be caused by denser rock types, such as iron-rich minerals, or by the presence of denser materials like metallic ores or large underground structures. Positive gravity anomalies can be useful for identifying potential mineral deposits or mapping subsurface geological structures.

Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans, leading to a rhythmic rise and fall of sea levels. However, tides do not directly affect the gravity on Earth's surface. The force of gravity at any location remains relatively constant, with minor variations due to factors like altitude and the density of Earth's materials.

The Earth's gravity pulls objects towards its center, including you, causing you to feel a downward force. When you stand on the ground, it exerts an equal and opposite force upwards on you, keeping you from falling due to gravity. This balance of forces allows you to stay firmly on the ground.

Gravity plays a crucial role in the death of a star by causing the core to collapse after nuclear fusion ceases. This collapse can lead to either a supernova explosion or the formation of a black hole, depending on the mass of the star. Gravity compresses the star's core, triggering intense reactions and releasing enormous amounts of energy, ultimately leading to the star's demise.

Gravity played a significant role in shaping Earth during its formation by pulling together particles and debris that eventually formed the planet. The intense gravitational forces caused the material to compress, resulting in Earth's spherical shape. Over time, the gravitational pull also influenced the distribution of Earth's landmasses and oceans, contributing to its current geological features like mountains and valleys.

The value of gravity on Earth is relatively consistent at approximately 9.81 m/s^2 near the surface. However, gravity can vary slightly depending on factors such as altitude, latitude, and geological features. These variations are small and generally not noticeable in day-to-day life.
