Gravity

Earth's gravity is caused by its mass (or rather its energy). Everything that has mass will passively generate a gravitational field, even you and me! (Although we are not by far massive enough for the gravitational attraction between us to be noticeable.)

It is not caused by the Earth's magnetic field, or the Earth rotation (in fact the rotation counteracts gravity in some places).

Determine the density of the sand. Determine the mass of the sand, and it's volume. Divide the mass by the volume and that gives you density. Then divide the sand's density by the density of water. That will give you the specific gravity of the sand. Because you divide densities, the units cancel out, and specific gravity does not have any units.

For example, you determine the density of the sand to be 10g/cm3, and the density of pure water is known to be 1g/cm3. Divide 10g/cm3 by 1g/cm3. The g/cm3 cancel, and you are left with just the number 10. So in this example the specific gravity of sand is 10.

Yes, gravity can cause mechanical weathering through processes like mass wasting, where gravity causes rocks and debris to move downhill. Ice can also cause mechanical weathering through frost wedging, where repeated freezing and thawing of water in cracks and crevices causes rocks to break apart.

Gravity itself is not considered a geological process, as it is a fundamental force that exists universally. However, gravity does play a vital role in geological processes, such as erosion, landslides, and plate tectonics, by influencing the movement and behavior of materials on and within Earth's surface.

The specific gravity of talc typically ranges from 2.5 to 2.8.

38% of Earth's gravity on the surface would be approximately 3.8 m/s². Earth's gravity at the surface is about 9.81 m/s², so 38% of that is calculated by multiplying 9.81 by 0.38.

The specific gravity of quartzite typically ranges from 2.65 to 2.75.

Black holes are the cause of gravity... Black holes are created when a supernova condenses, creating a black hole. It condenses because gravity has won the battle between the star's core.

So basically, gravity fuels a Black hole.

A man cannot resist the gravitational pull of Earth, as gravity is a fundamental force of nature. Gravity is what keeps us grounded to the Earth's surface and allows objects to maintain their position in space.

Geotropism is the term that describes the root's downward growth in response to gravity. This phenomenon helps roots navigate through soil to access water and nutrients effectively.

Electromagnetic force and gravitational force are very different in a number of ways. Perhaps the most significant difference is that there are both positive and negative electrical charges, and north and south magnetic poles, whereas there is only one, positive form of gravity (if we could produce negative gravity, long dreamed of by science fiction writers, that would be tremendously useful). Electric forces interact with shielding agents (in the form of electrical conductors) and are absorbed, and do not reach the shielded interior of the room, but gravity is not absorbed in that way - it permeates everything equally. The ultimate nature of gravity is more mysterious than that of electromagnetism, and is still under debate by theoretical physicists. If it is true as suggested by Einstein that gravitational force is the result of a warping in the geometry of four dimensional space-time, you can see why it would be difficult to shield against it.

The effects are the moon phases, eclipses, and the high tide and low tide.

The specific gravity of soil is a valuable parameter for assessing soil properties like compaction and permeability. A higher specific gravity typically indicates a denser soil with better load-bearing capacity, while a lower specific gravity may suggest a more porous soil with lower strength. Overall, specific gravity measurements can help in understanding the engineering behavior and suitability of soil for different construction purposes.

On or near Earth's surface, the force of gravity on any mass is 9.8 newtons per kilogram.

The force of gravity that any mass on or near the surface exerts on the Earth is

also 9.8 newtons per kilogram.

There are no specific predictions for what will happen to Earth in 2021. However, ongoing concerns such as climate change, natural disasters, and environmental degradation will continue to impact the planet. It is important to focus on sustainability and conservation efforts to mitigate these effects.

The barycenter is the point between the Earth and the Moon where they balance each other's gravitational pull.

The Moon would continue to orbit the Sun, possibly in a different orbit. Assuming the Moon kept its (Earth) orbital velocity, this would cause it to move either slightly closer or slightly farther from the Sun. The Moon's relative velocity to the Earth is about 1 km/sec whereas the Earth-Moon system orbits the Sun at 30 km/sec. The sudden disappearance of the Earth would mean the continuation of the Moon's solar orbit, albeit possibly altered.

Venus' gravity is about 91% of Earth's gravity, which means that objects on Venus weigh about 91% of what they would weigh on Earth. This is due to Venus having a similar mass to Earth but a slightly smaller radius.

Yes. Venus has less mass and therefore has less gravity.

Gravity keeps 99 percent of the total mass of the atmosphere within 32 km of Earth's surface. This force prevents the gases in the atmosphere from escaping into space and holds them close to the Earth's surface.

Geotropism or gravitropism are terms that describe a plant's root growth in response to gravity. Positive geotropism refers to roots growing downwards towards Earth, while negative geotropism refers to roots growing away from gravity, such as when they grow upward in a climbing plant.

Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia

No, a mass movement occurs due to the force of gravity acting on sediment or rock material, causing it to move downhill. This movement can happen slowly over time or more rapidly as in landslides or rockslides. The mass movement is a result of the force of gravity on the material rather than being called a gravity.

Heavy rains in the mountains can lead to flooding because the steep slopes cannot absorb the excess water quickly enough, causing it to flow downhill rapidly. This sudden rush of water can overwhelm rivers and streams, leading to overflow and flooding downstream areas. Additionally, the heavy rain can saturate the soil, increasing the risk of landslides and further exacerbating flooding.
