Gravity

It helps to look at the formula for gravitational attraction. The force of gravity between two objects depends on:* The gravitational constant (which doesn't change)

* The mass of the one object

* The mass of the other object

* The distance between them

Mass movements of land due to gravity, such as landslides, occur when the force of gravity exceeds the strength of the material holding the land in place. This can be triggered by factors such as heavy rainfall, earthquakes, or human activities. The movement of the land mass can range from slow creeping to rapid, destructive slides.

Gravity plays a crucial role in the water cycle by pulling water downward, causing precipitation like rain and snow. Gravity also allows water to flow from higher elevations to lower elevations through rivers and streams, eventually returning water to the oceans where the cycle begins again.

Gravity played a key role in the formation of Earth by pulling together gas and dust in space to form the protoplanetary disk from which our planet eventually emerged. The gravitational force between particles in the disk led to the clumping of materials, eventually forming Earth through a process known as accretion.

because thermocol is lighter than water

Water can flow over rock surfaces, carrying sediment and causing abrasion. Gravity helps in pulling this sediment downstream, wearing away the rock surface over time. The force of gravity also plays a role in causing water to flow downwards, increasing its erosive power on rocks.

Moisture absorbed by cement particles can increase the weight of the cement, leading to a higher specific gravity. This is because moisture adds mass to the particles without significantly increasing their volume, resulting in a denser material. Monitoring and controlling the moisture content is important in concrete production to ensure proper mixing ratios and overall quality of the final product.

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.
