Earth Sciences

Solstice comes from the Latin words "sol" (sun) and "sistere" (to stand still). It refers to the moment when the sun reaches its highest or lowest point in the sky, resulting in the longest or shortest day of the year.

The lithosphere includes the uppermost part of the mantle and it also includes all of the crust.

Colorful flowers are usually pollinated by attracting pollinators such as bees, butterflies, and birds with their bright petals and sweet nectar. These pollinators are drawn to the colors and scents of the flowers, and in the process of feeding on the nectar, they transfer pollen from one flower to another, aiding in the pollination process.

The advantages to a flat thin leafs blade is that the green chlorophyll has more exposedsurface area to absorb sunlight and allows for photosynthesis to take place and more progressively than in smaller leaves with less surface area.

Water moves from Earth to air through the process of evaporation, where heat from the sun causes water on the Earth's surface to turn into water vapor. This water vapor rises into the atmosphere and can then condense to form clouds. When the clouds become saturated, water falls back to Earth as precipitation in the forms of rain, snow, sleet, or hail. This cycle of evaporation, condensation, and precipitation is known as the water cycle.

Color is not always a good way to identify minerals because some minerals change colors at certain temperatures. Some minerals have several colors and some are found in varied colors.

Convection currents are the movement of fluids, such as air or water, caused by temperature differences. As a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks to replace it, creating a circular motion. This process is driven by the transfer of heat through the fluid.

Sometimes referred to as groundwater contamination, groundwater pollution is not as easily classified as surface water pollution, as contamination may not be easy to recognise. Groundwater, by it's very nature, is more susceptable to contamination from sources that may not directly affect surface water bodies. Groundwater can become contaminated by those drilling for oil or gas wells.

Groundwater may be polluted through a spill or ongoing realease of chemical or radionuclide contaminents into soil, polluting the aquifer below yet not the surface water body above. This is defined as a toxin plume, and as it travels it is defined as a plume front.

Analysis of groundwater pollution usually focuses on the soil characteristics, geology, hydrogeology, hydrolgy and the nature of the contaminants at the site.

A depression contour is a contour line that represents a lower elevation compared to the surrounding terrain. A contour line is a line on a map connecting points of equal elevation, indicating the shape of the land surface.

A magma containing not much silica (= SiO2). For example: a basaltic magma.

These magma's have a low viscosity since the lower the SiO2-content, the lower the viscosity; and hence flow easily (↔ a felsic magma).

The crest of a flood stage can vary greatly depending on the number of tributaries and the distribution of rain or snow melt. The lower (downstream) portions will almost always crest later due to the movement of the water volume. Even after the crest, which is the high point of the water, flooding can continue for lengthy periods until the water drains. The time required for this is also dependent on additional rain, blockage of exit paths, or comparative elevation for the flooded areas.

Neon is important primarily for industrial and commercial use, such as neon lighting and advertising signs. It is also used in cryogenics to create very low-temperature environments. In terms of Earth's atmosphere, neon is a minor component and does not play a significant role in environmental or biological processes.

Bacteria are a type of microbe.

Dirt is the generic name for a mixture of organic and inorganic materials, as such it is not a microbe. However, dirt frequently contains bacteria as a constituent.

The latitude is the measure of an areas distance from the sun while the longitude is the measure of the angular distance on earth's surface. The latitude measures the climate and therefore the type of biome in a given area.

The sun is infact an abiotic factor, because it is not a living creature, it is a ball of fire. A star. It is because of the sun that we can have weather,biomes and other kinds of abiotic factorts.

A solute is the substance that the solvent is being dissolved in. For some things (e.g. two liquids) it's a bit ambiguous. Typically if there's a need to specify which is which the predominant component is designated the solvent, though if water is one of the components then it is often considered to be the solvent even when it's not the primary ingredient. Rubbing alcohol, for example, is usually labeled as a 70% solution (of 2-propanol in water) and not as a 30% solution of water in 2-propanol.

The amount of water actually contained in air compared to the amount it could contain is known as relative humidity.

Pumice is a common type of Igneous rock used in soil mixes. It is lightweight and porous, which helps improve aeration and drainage in soil. Pumice is also resistant to decomposition, making it a long-lasting addition to soil mixes.

The moon rotates in such a way that one face always points towards the Earth. This is because the Earth has tides - over time the tidal forces gradually removed energy from the Moon's rotation so it ended up always facing the Earth.

Energy doesnt run out, it is just transferred. For example, a ball in a high place is said to have potential kinetic energy, if it then falls that energy is transferred to kinetic and thermal energy. Upon rest, the ball again has potential kinetic energy.

The majority of the energy on Earth comes from the Sun. Sunlight is converted into various forms of energy that power life on Earth, such as in photosynthesis for plants or solar power for electricity generation. Other sources of energy on Earth include geothermal energy from the Earth's heat and the energy stored in fossil fuels like coal, oil, and natural gas.

The three major reasons why Earth continues to exist:

1. There is a constant supply of energy.

2. Matter cycling provies us the nutrients necessary to live.

3.Gravity keep these nutrients within our reach.

Corundum is transparent as a mineral, especially in its gemstone forms such as sapphire and ruby. The level of transparency can vary depending on the quality and any inclusions present in the crystal structure. In general, corundum is prized for its transparency and clarity when cut and polished as a gemstone.

Garnet is an example of a mineral that has a basic structure consisting of isolated tetrahedra linked by atoms of other elements. In garnet, each tetrahedron shares oxygen atoms with neighboring tetrahedra, creating a three-dimensional framework. The cations occupying the spaces in between the tetrahedra give garnet its characteristic structure and properties.
