Freezing phase has taken place when molten lava pours from a volcano and after a few hours, the liquid lava hardens into a shiny gray rock.
What substances make up lava?Crystals, volcanic glass, and bubbles make up the components of lava (volcanic gases). Magma starts to crystallize olivine and produce volcanic gas bubbles as it cools and approaches the surface. A mush of crystals, liquid, and bubbles make up the lava when it erupts.
Why does lava get so hot?Two main factors make lava popular: Deep under the Earth (approximately 100 km below the surface), when rocks melt to form magma, it is extremely hot due to pressure and radiogenic heating. The rock around the magma acts as a good insulator, preventing it from losing much heat as it rises to the surface.

Manual irrigation is often used by the small-scale farming operations, and it requires extensive labor to set up the individual irrigation lines.
What is irrigation?The agricultural practice of applying measured amounts of water to land to help in crop production, as well as to help develop landscape plants and lawns, is known as irrigation, however it is also sometimes referred to as watering. Rain-fed agriculture is defined as that which relies solely on direct rainfall and does not utilize irrigation. Over 5,000 years ago, irrigation became a key component of agriculture, and many different cultures all over the world independently developed it. In arid locations and during times of below-average rainfall, irrigation supports the growth of agricultural crops, the upkeep of landscapes, and the revegetation of disturbed soils. The intention is to water plants as equally as possible, ensuring that each plant receives the proper quantity of moisture—neither too much nor too little.

if an organism contains 600g of carbon- 14 in its tissues when it dies, how many grams of carbon-14 would remain after 5 half lives show your work to earn full credit
Answer:
The half-life of carbon-14 is 5730 years, so after 5 half-lives, 5*5730 = 28,650 years will have passed.
The decay of carbon-14 follows an exponential decay curve, so after 5 half-lives, the amount of carbon-14 left will be 1/32 of the original amount.
Therefore, after 5 half-lives, the amount of carbon-14 left will be 1/32 * 600g = 18.75g.
This is the final answer.
CORRECT ME IF I'M WRONGthe mechanism by which rocks store and eventually release energy in the form of an earthquake is called group of answer choices stress fracture fault displacement seismic rebound elastic rebound
Elastic rebound is the process by which rocks store energy that eventually releases as an earthquake.
The incidence of earthquakes is explained by the elastic-rebound theory. Earthquakes are produced when bending rocks fail and release their stored stress energy. In geology, the study of how energy is released following an earthquake is known as elastic-rebound theory. Along the fault line, the crust ruptures; the quick motion releases the built-up energy, and the rocks almost immediately return to their previous shape. Elastic rebound is the ability of the deformed rock to restore its original shape in a new position as a result of the slide along a fault (i.e., earthquake). Elastic rebound describes the process by which a rock that has been deformed by an earthquake's sliding along a fault can return to its former shape.

Quick, please, who operated the Underground Railroad?
Answer:
Harriet Tubman
Explanation:
do tides occur in the molten interior of earth for the same reason that tides occur in the oceans?
Yes, as a result of the disparity in gravitational pull along the core.
There are two factors that affect how much perceived gravitational acceleration (g) varies at various locations on Earth (as you implied). The Earth is not a perfect sphere; as a result, places near the equator are farther away from the center of mass. The Earth is slightly flattened in the poles and bulges out near the equator.
The gravitational force between two things depends on the separation between their centers of mass, hence at the equator as opposed to the poles, the force of gravity on an item is smaller. The gravitational acceleration is about 0.18% lower at the equator than at the poles due to this factor alone.
Second, although it has no effect on the attraction between two masses, the rotation of the Earth results in an apparent centrifugal force that points away from the axis of rotation and can counteract the gravitational pull. At the equator, the centrifugal force is equal to zero and points directly against the gravitational force. In comparison to the poles, the centrifugal force and center of mass distance together lessen g by around 0.53% at the equator.

What is drought?
A drought is characterized by drier than usual weather. A drought, then, is "a moisture deficit compared to the average water availability at a specific area and season," according to this definition. Days, months, or even years may pass between droughts. The ecosystems and agriculture of afflicted areas are frequently severely impacted by drought, which also has a negative influence on the local economy. The likelihood of a drought and consequent wildfires are considerably increased during the annual dry seasons in the tropics. Heat waves can make drought conditions much worse by accelerating the evaporation of water vapour.
Most regions of the world often experience drought, which is growing more extreme and unpredictable as a result of climate change, which dendrochronological studies trace back to 1900. Environmental, economic, and social repercussions are the three different types of drought effects.

The planet produces heat energy . The temperature rises as you move deeper. Temperatures soar to 750°C about 25 km below the surface, and are reportedly 4,000°C near the core.
Heat energy is produced by the planet. Moving deeper causes the temperature to increase. At 25 kilometers below the surface, temperatures at the core are thought to be 4,000°C. Hot springs have been used by people since antiquity, and we currently use geothermal technology to heat our apartments. Geysers, earthquakes, and volcanic eruptions are all indications of the Earth's core power source.
The term "radioactive decay" refers to the method by which Earth generates heat. It involves the breakdown of naturally occurring radioactive materials within Earth, such as uranium, for instance.

why does the earth have seasons, 3-5 sentences
Answer:
The earth has seasons because of its tilted axis. The earth's axis is tilted by about 23.5 degrees relative to its orbit around the sun. This means that different parts of the earth receive different amounts of sunlight at different times of the year. When the earth's North Pole is tilted towards the sun, the Northern Hemisphere experiences summer, while the Southern Hemisphere experiences winter. When the earth's North Pole is tilted away from the sun, the Northern Hemisphere experiences winter, while the Southern Hemisphere experiences summer. The changing angle of the earth's axis relative to the sun causes the seasons to change throughout the year.
Answer:
The main reason we have seasons is because the Earth is tilted on its axis. The hemisphere that is tilted towards the sun receives the most sunlight as the Earth revolves around the sun.
