Zero will be the age that the radiometric dating will give for a chunk of recently solidified lava from Kilauea, an active volcano in Hawaii
What is Radiometric dating?
Using radioactive isotopes, radioactive dating is a technique for determining the age of rocks and minerals. The stratigraphic correlation approach, which is used to date sedimentary rocks, cannot be used to date igneous and metamorphic rocks.
There are more than 300 known naturally occuring isotopes. Some remain the same throughout time and produce stable isotopes (i.e. those that form during chemical reactions without breaking down). The radioactive isotopes that are unstable or are more widely known as radioactive decay into other isotopes. Natural radioactive decay results from the atomic nucleus becoming unstable and releasing fragments. Radioactive particles are released as a result (there are many types). When the number of protons and neutrons in the nucleus is balanced by this decay process, the atom becomes stable.
As the chunk is totally fresh, thus the age will be zero

Differences in temperature drives surface ocean circulation
What is ocean current?
Understanding how heat energy transfers between Earth's water bodies, landmasses, and atmosphere depends on mass flows of water, or currents. Since the oceans retain 97 percent of the planet's water and cover 71 percent of its surface, they play a significant role in the storage and global transfer of thermal energy. This heat is carried by regional and global ocean currents, which have an impact on the stabilisation of global climate patterns, the cycling of gases, and the delivery of nutrients and larvae to marine ecosystems.
Ocean surface and deep waters below 300 metres are where ocean currents are found (984 feet). Both locally and globally, they can flow water horizontally and vertically. The wind, tides, Coriolis effect, sun, solar energy, and changes in water density all contribute to the ocean's complex current or circulation system. Ocean currents are also influenced by the terrain, shape, and surrounding landmasses of ocean basins. The size, shape, speed, and direction of ocean currents are influenced by these forces and physical properties.

Using the theories of shoreline, we got that longshore current is turbulent water current that carries sand and flows within the surf zone parallel to the shoreline.
Hard shoreline stabilization includes the various fixed, immovable structures designed to hold an eroding shoreline in the place. Hard stabilization is one of the most common modifiers of the topography in the coastal zone and is discussed further more detail below. Seawalls, jetties, groins, and offshore the breakwaters interrupt sediment exchange and reduce shoreline flexibility to respond to the wave and tidal actions. Armoring the shoreline changes the location and intensity of the erosion and deposition. Indirectly, hard shoreline stabilization gives the false sense of security and encourages increased development landward of walls, placing more and more people and property at risk from the coastal hazards including waves,

7. What is a pronatalist factor that might have made the total fertility rate higher in some years?
Answer:This entry focuses on the number of births per woman in a population. The most commonly used metric is the Total Fertility Rate (TFR) – or often simply ‘fertility rate’ – which measures the average number of children per woman.1
The global average fertility rate is around 2.3 children per woman today. Over the last 50 years the global fertility rate has halved. And over the course of the modernization of societies the number of children per woman decreases very substantially. In the pre-modern era fertility rates of 4.5 to 7 children per woman were common. At that time the very high mortality at a young age kept population growth low. As health improves and the mortality in the population decreases we typically saw accelerated population growth. This rapid population growth then comes to an end as the fertility rate declines and approaches 2 children per woman.2
The first section of the entry presents the global empirical perspective on the number of children per woman. The long second section presents the academic research that answers the question why the number of children per woman declined. Particularly important are 1) the empowerment of women in society and in relationships – through education, labor force participation, and strengthened women’s rights – and 2) the increased well-being and status of children.
Explanation:
The global total fertility rate, or average number of children a woman is estimated to have in her life, has been falling since the 1960s. Today, the total fertility rate (or TFR) is half of what it was five decades ago. But while women overall are having fewer children than in the past, total fertility rates still vary greatly among countries. Why, when, and if a woman has a child involves many complex societal, economic, and political factors.

What is disaster management?
Disaster management is the process by which we "prepare for, respond to and learn from the effects of severe failures." It is how we cope with the human, material, economic, or environmental impacts of a given disaster.
Disasters can have human causes, despite the fact that nature frequently causes them. Disasters are viewed by emergency managers as recurrent events that include four phases: mitigation, readiness, response, and recovery.
The objectives of disaster management initiatives are to minimize or eliminate possible losses from hazards, ensure immediate and appropriate support to catastrophe victims, and achieve a quick and efficient recovery.
Disasters are significant setbacks to a community's ability to function that go beyond what it can handle on its own. Natural, man-made, and technical risks, as well as a number of other variables that affect a community's exposure and vulnerability, can all result in disasters.

Rocks, minerals, and soils disintegrate through a process known as physical weathering, sometimes known as mechanical weathering. Abrasion is the main physical weathering process (the process by which clasts and other particles are reduced in size).
Temperature, pressure, frost, root movement, and burrowing animals can all cause physical deterioration. For instance, physical weathering will expose more surface area through the use of fractures, speeding up the pace of deterioration.
Around the world, gorges, ravines, and valleys are formed by processes of water, ice, and wind that are laden with silt. Huge flowing ice masses packed with soil and rock fragments in glacial regions transport away vast quantities of materials while crushing rocks in their course. Rocks can disintegrate to some extent when plant roots squeeze into cracks and tear them apart. Animal burrowing can also contribute to the disintegration of rocks.

Lithification is a difficult process that turns loose silt grains that have just been deposited into rock. Lithification might take place either right away or later after a sediment is deposited. One of the key procedures, particularly for sandstones and conglomerates, is cementation. In addition, interactions between different minerals and between minerals and the fluids confined in the pores within a sediment occur; these processes, together referred to as autheigenes, may create new minerals or supplement those already present in the sediment.
Minerals in solution entering the sediment from another region may be deposited or may interact with minerals already there. Minerals may also be dissolved and redistributed form nodules and other concretions. By pressing the grains into different arrangements, the sediment may be compressed.

The temperature on the foothills will be hot, while the temperature at the top of the hill will be cooler.
The altitude of a place can factor in temperature conditions. This is related to the relationship between temperature and air pressure.
The higher we are above sea level, the lower the air pressure. In conditions with low air pressure, air molecules will move more slowly, so no collisions between air molecules occur. As a result, less heat is created, the temperature will feel cooler. Conversely, the lower it approaches sea level, the higher the air pressure which creates a hotter temperature due to the denser air molecules.
