Understanding Key Earth and Space Concepts

Leap Year

A year with an additional day at the end of February, occurring every 4 years.

Orbit

The elliptical movement of the Earth around the Sun.

Cold Zones

Thermal zones where the Sun's rays strike the surface at a wide angle, resulting in low temperatures.

Temperate Zones

Thermal zones where the Sun's rays strike the surface at a moderate angle, resulting in mild temperatures.

Tropical Zones

Thermal zones where the Sun's rays strike the surface nearly perpendicularly, resulting in high temperatures.

Tilt

The inclination of the axis of rotation.

Cardinal Points

Basic reference points that allow us to find our location on Earth: North, South, East, and West.

Rotation

The movement of the Earth around its axis. Consequences... Continue reading "Essential Earth & Space Terms Defined" »

Evidence from Rocks About Life

Rocks are an important source of information about many forms of life that existed on this planet.

Why Can't Scientists Be Sure How Earth Was Created?

Because no rocks date to the formation of the Earth.

How Fossil Teeth Reveal an Animal's Diet

Size and shape indicate diet.

Explaining Relative Dating of Fossils

Sedimentary rocks form layers, with newer layers added on top of older layers. This does not tell scientists the exact age of the fossil; however, it does tell the scientist the fossil's age in relation to other fossils above or below it.

Common Radioactive Isotopes

Potassium-40 and Carbon-14 are two common radioactive isotopes.

What Is a Mass Extinction?

A mass extinction is when many organisms disappear from the... Continue reading "Unlocking Earth's History: Fossils, Rocks, and the Story of Life" »

SYSTEMS

Can be small or large, living or non-living.

Types: open, close and isolated

• Open: exchanges both energy and matter
• Close: only exchange energy
• Isolated: Energy and matter is not exchange

Transfer: Basic flow through a system. Change in location of energy or matter.

Transformation: A new product is created. Change of state.

First law or thermodynamics: energy in an isolated system can be transformed but cannot be created or destroyed.

Second law or thermodynamics: is lost in the different levels of a system.

Entropy: is a measure of the amount of disorder in a system.

Negative feedback:

Positive feedback:

PRODUCTIVITY

Is the conversion of energy into biomass over a given period of time.

Biomass: is the living mass of an organism

Gross: total amount... Continue reading "Understanding Systems, Productivity, Global Warming, and Photochemical Smog" »

Geography of Bosnia and Herzegovina

The relief of Bosnia and Herzegovina is mainly hilly and mountainous, with only 13.53% of the land situated between 0-200 meters above sea level. Bosnia and Herzegovina has a surface area of 51,209 square kilometers, of which the seaside is 12.2 square kilometers. In 1991, 4.38 million people lived in the country. Based on this, the average population density is around 85 inhabitants per square kilometer. According to the results of the 2013 census, there are 3,531,159 inhabitants in the territory of Bosnia and Herzegovina. Today, about 70% of the population lives in urban areas.

Bosnia and Herzegovina is shaped like a triangle. One side extends east-west, the other north-south, while the hypotenuse runs northwest-... Continue reading "Geography and Geology of Bosnia and Herzegovina" »

Echo sounding: is a type of sonar used to determine the depth of water by transmitting sound waves into water.

Trieste: is a city and a seaport in northeastern Italy. What is Trieste famous for? In the 19th century the monarchy was one of the Great Powers of Europe and Trieste was its most important seaport.

Deep sea winch: Fishing rod, mechanism

drift bottle : a bottle containing a record of the time and place at which it was set adrift in the ocean for supplying when recovered data to aid in determining the circulation of surface waters in the ocean

drogue: a device, typically conical or funnel-shaped with open ends, towed behind a boat, aircraft, or other moving object to reduce speed or improve stability.

The Geological Foundation of Bosnia and Herzegovina

Sediments were fractured and collected. The deposition of Silurian sediments, which subsequently serve as the basis for all other geological strata and the relief of Bosnia and Herzegovina, ceased more than 400 million years ago. Upon this Silurian base, layers from the early and late Palaeozoic era (i.e., the Devonian and Carboniferous periods) were deposited in the same ocean basin.

Palaeozoic Sediments: Composition and Distribution

The Palaeozoic sediments are presented mostly as clastic and less commonly as carbonate formations, which are metamorphosed in some places. Palaeozoic sediments can mainly be found in the following regions:

• The Una-Sana area
• The Central Bosnian Schist Mountains
• Eastern

Mesozoic Sediments in the Dinarides

Mesozoic sediments in the outer Dinarides are classic carbonate sediments, while the central and inner Dinarides have volcano-sedimentary and flysch sediments.

Triassic Period

The Triassic sediments spread over the Vrnograč and Bosanski Novi band over western Bosnia, north and northeast Herzegovina, and southeast Bosnia. The second broader band goes from Vareš over Olovo, Glasnica, and Romanija to Višegrad.

Jurassic Period

The Jurassic period sediments occupy the largest part of the outer Dinaric zone, where it is mostly developed in the limestone-dolomite facies. It is located in the area of Bihać to Gacko and Trebinje. The Jurassic age volcano sediment formations are also found in the central zone from Kozara...

Sound Changes in Historical Linguistics

Assimilation

Assimilation occurs when a sound becomes more similar to an adjacent sound in voicing, manner, or place of articulation. The direction of assimilation can be:

• Regressive: For example, Old English wifman becomes wimman.
• Progressive: For example, Germanic *wulno becomes wullo and then Old English wull.

The extent of assimilation can be:

• Total: For example, Old English wifman.
• Partial: For example, Latin in + premiere becomes impremiere.

Assimilation can also be relative to the environment, such as:

• Immediate: For example, English attain.

Palatalization

Palatalization is a process in which a front vowel causes a sound to move forward or backward to become more palatal in articulation. For example:

• Old English
