Facts about nature

The Atacama Desert in Chile is one of the driest places on Earth, with some areas receiving almost no rainfall for centuries. But why doesn’t it rain in the Atacama? The answer lies in a mix of geographical, climatic, and atmospheric factors. From powerful wind patterns to ocean currents that block moisture,...

The Big One is a term used to describe a potentially catastrophic earthquake expected to strike along major fault lines, such as the San Andreas Fault. Experts warn that when it happens, it could cause widespread destruction, aftershocks, and even tsunamis. But when might The Big One hit, and how dangerous...

Beneath the Earth's surface lies a hidden network of subterranean rivers, quietly flowing through limestone caverns and porous rock formations. These mysterious waterways play a crucial role in the planet's hydrological cycle, influencing groundwater movement and cave formation. But what exactly are subterranean...

Why do we have seasons? It's a question that touches everything from our weather to the way nature behaves. Despite the common belief, it's not about Earth's distance from the Sun. The real reason is our planet's 23.5-degree axial tilt. This tilt stays consistent as Earth orbits the Sun, meaning different...

Water exists in many forms, each with unique characteristics shaped by natural processes or human intervention. While water covers much of the globe, its availability and usability vary significantly depending on its source, composition, and treatment. Understanding these variations is crucial for both...

It's easy to forget that plants are constantly exchanging gases with the air, a process far more complex than our own breathing. From the tiny pores on a leaf to the massive gas exchange of ocean algae, plant respiration is vital for all life on Earth. Plants don't have lungs like us. Instead, they've...

Why are snowflakes white while ice cubes are clear? It's all about how their structures interact with light. Snowflakes' complex, airy crystals have countless surfaces that scatter light in all directions (diffuse reflection), making them appear white. Ice, with its tightly packed structure, allows light...

Apart from animals, plants are the only organisms which have vascular tissues. This only applies to vascular plants, since non-vascular plants have a more simple structure. In biology, tissues are a collection of cells which work together to perform a particular function, but which are less complicated...

World Snow Day is celebrated on the third Sunday of January every year. In 2025, it will be celebrated on 19th January.

Such seismic phenomena include earthquakes, volcanic eruptions and even those induced by human activity such as those caused by explosions. Incorporating elements such as a seismometer and seismogram,...

The Mercalli Intensity Scale measures earthquake effects through observable damage and human experience, using 12 levels from barely noticeable tremors to total destruction. Created in 1902 and modified in 1931, this scale helps emergency responders assess damage patterns and engineers design seismic-resistant...

Earthquakes are geological hazards which occur due to the movement of tectonic plates in the Earth's crust. Their study requires specific tools and scales to measure their magnitude, intensity and effects. The Richter scale is a method that measures the energy released at the epicenter of an earthquake...

For most of us, the concept of fruit vs. vegetable is mainly a culinary distinction. Generally speaking, we go to vegetables when we want something savory and fruit when we want something sweet. However, this distinction is not accurate when it comes to categorizing fruits and vegetables. To really know the...

Have you ever imagined a tree towering as high as a 35-story building? These natural giants do exist, although their canopies often reach above the clouds, hidden in remote and hard-to-reach places. While many trees grow to impressive heights, one stands above the rest as the tallest living being on Earth....

It involves the movement of carbon between the atmosphere, oceans, land, and living organisms. Understanding the carbon cycle is essential for comprehending climate change and the interconnectedness...

Volcanic calderas are complex geological structures that form after massive volcanic eruptions, leaving an indelible mark on the Earth's landscape. Named after the Spanish word for ‘cauldron’ or ‘boiler’, they are large depressions which can vary greatly in size and other characteristics. They are formed as...

Volcanic winters occur when powerful volcanic eruptions release massive amounts of ash and gases, primarily sulfur dioxide, into the atmosphere. These particles reflect sunlight, causing global cooling. This temporary climate disruption can last for months or even years, affecting weather patterns, agriculture,...

Supervolcanoes are volcanic structures that can produce eruptions of extremely high magnitude. Known as supereruptions, they release more than 1,000 cubic kilometers of volcanic material in a single eruption event. Traditional volcanoes tend to have a localized impact, but supervolcanoes can have significant...
