An object that has low density is lightweight for its size and an object that has high density is heavy for its size.
Density refers to a measurement of material's mass per unit of volume. The density of material is the denseness of the material within a specific area. In other words, it is essentially a measurement of how tightly matter is packed together and is a unique physical property of a material. The principle of density was discovered by the Greek scientist Archimedes. The formula for density is given as d = M/V, where d is density, M is mass, and V is volume. It is a measure of how heavy something is for its size. Hence, if something is heavy for its size, it has a high density. If an object is light for its size it has a low density.

hurricane season for the atlantic ocean lasts from june to november. which factor makes an atlantic hurricane less likely to form during the month of march?
The cool ocean water makes Atlantic hurricane less likely to form during month of march.
What is an Atlantic hurricane?An Atlantic hurricane is a tropical cyclone that forms in the Atlantic Ocean, typically between the months of June and November. It is also referred to as a tropical storm or simply a hurricane. The only factor that separates a hurricane from a cyclone or typhoon is location. The United States National Hurricane Center monitors the basin and issues reports, watches, and warnings about tropical weather systems for the North Atlantic Basin. It is one of the regional specialized meteorological centers for tropical cyclones, according to the World Meteorological Organization. In order to prevent confusion if a different storm later adopts the same name, a hurricane's name may be removed from the list upon request from the affected countries if it significantly damages or kills people.

What is the affect of soil acidification on nitrogen cycle?
The process of soil acidification, which results in a reduction in soil pH over time and can influence both surface soil and subsurface, is sped up by agricultural activity.
The supply of nitrogen may be decreased if beneficial soil microorganisms are prevented from recycling nutrients. In addition to possible calcium, magnesium, and molybdenum deficits, phosphorus in the soil becomes less available to plants. It may become more difficult for plants to use moisture from the soil.

on which continent could you potentially see live colonies of all extant honey bee species?
Except for Antarctica, every continent has native bees. Bees are present wherever there are flowering plants that are pollinated by insects, including in forests, farms, towns, and rural areas.
Bees are winged insects related to ants, wasps, and beetles. They are most known for their pollination abilities and, in the case of the western honey bee, for making honey. Within the superfamily Apoidea, the monophyletic lineage of bees can be found. Currently, they are regarded as belonging to the clade Anthophila. Bees are classified into seven recognized biological families and over 16,000 different species. Most species (>90%) are solitary, including mason bees, carpenter bees, leafcutter bees, and sweat bees. Some species, such as honey bees, bumblebees, and stingless bees, live socially in colonies. There are bees in every ecosystem on the earth that supports insect-pollinated blooming plants, with the exception of Antarctica. The Halictidae, or sweat bees, are the most prevalent bees in the Northern Hemisphere, yet due to their small size, people frequently mistake them for wasps or flies. Bees come in a variety of sizes, from tiny stingless bee species with workers that are less than 2 millimetres (0.08 in) long to the largest species of leafcutter bee, Megachile pluto, with females that may grow as long as 39 millimetres (1.54 in). Bees consume pollen and nectar, the latter for its protein and other nutrients and the former largely as an energy source. Most pollen is consumed by their larvae as nourishment. Primates and bee-eating birds are examples of vertebrate bee predators, whereas beewolves and dragonflies are examples of insect predators.

the ocean floor moves how much per year?
Answer:
The ocean floor moves at different rates depending on the location. In some areas, the ocean floor can move as little as a few millimeters per year, while in other areas it can move several centimeters or more per year. This movement is caused by a variety of factors, including tectonic plate movement, earthquakes, and volcanic activity.
Answer:
It spreads about 6-16 centimeters (3-6 inches) every year. There is not an ocean trench at the East Pacific Rise, because the seafloor spreading is too rapid for one to develop!
Explanation:
which of the following best describes the age of the seafloor? group of answer choices actually, all of the statements correctly describe the age of the seafloor the oldest rocks are located at ocean basin margins the youngest rocks are located at ocean ridges there are no rocks older than 200 million years (older rocks have been subducted)
All of the statements regarding oldest and younger rocks correctly describe the age of the seafloor.
Tectonic plates that are moving relative to one another make up the Earth's surface. It is possible to produce new sea bottom as the plates shift. Where plates separate, molten lava from under the Earth's surface forms new crustal material. As a result, the Mid-Atlantic Ocean Ridge and other divergent borders are where you can find the youngest sea rocks.
The magnetic polarity of the ocean floor is used by scientists to estimate age. On the sea floor, only a little portion older than 150 million years. This is due to new surfaces gradually replacing the older sea bottom as it is subducted beneath other plates. New surfaces are continually being generated as a result of the shifting tectonic plates.

Typically, wind direction is determined by the direction it is coming from. A north wind, for instance, blows from the north to the south. Onshore winds, which blow from the ocean toward the shore, and offshore winds are the exceptions (blowing off the shore to the water). Typically, wind direction is expressed in degrees or cardinal (or compass) directions. As a result, a wind blowing from the north is referred to as having a wind direction of 0° (360°); a wind blowing from the east is referred to as having a wind direction of 90°; etc. Typically, wind speed and direction are combined in weather forecasts; for example, "northerly wind at 15 km/h" refers to a wind that is coming from the north and has a speed of 15 km/h.

Answer:-As a gas giant, Jupiter doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either. Jupiter creates a lot of internal heat and releases this heat by emitting thermal radiation. In fact, Jupiter creates so much internal heat that it emits almost twice as much energy as it receives from the Sun. Jupiter's magnetosphere is the largest object in the solar system. If it glowed in wavelengths visible to the eye, it would appear two to three times the size of the Sun or Moon to viewers on Earth. The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth's terra firma.
