Pigments are molecules in leaves that are responsible for giving them their color. The main pigments in leaves are chlorophyll, carotenoids, and anthocyanins. Chlorophyll is responsible for the green color of most leaves, while carotenoids give leaves their yellow and orange hues, and anthocyanins are responsible for the red and purple colors.
The process in plants that regulates the level of oxygen and carbon dioxide in the atmosphere is called photosynthesis. During photosynthesis, plants use the energy from the sun to convert carbon dioxide and water into oxygen and glucose. The oxygen produced is released into the atmosphere, while the glucose produced is used by the plant …
The main reason for the decreasing oxygen level in the atmosphere is the burning of fossil fuels and deforestation. Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, which reduces the amount of oxygen available. Deforestation also contributes to the decrease in oxygen levels, since trees are a major source of oxygen …
Global warming is causing a number of drastic changes to the Earth’s climate. Rising temperatures are melting polar ice caps, leading to rising sea levels, extreme weather events, and increased acidification of the oceans. This is causing habitats to be destroyed and species to become extinct. It is also leading to more frequent and intense …

Global warming is the long-term warming of the planet due to an increase in the average temperature of the Earth’s atmosphere, primarily caused by the release of certain gases, such as carbon dioxide, from human activities, such as the burning of fossil fuels and deforestation. This increase in global temperatures can lead to a variety …
On December 26, 2004, a massive 9.0 magnitude earthquake off the coast of Indonesia caused a devastating tsunami to hit the coastal areas of Kerala, India. The tsunami had a devastating impact on the region, with thousands of lives lost and millions of dollars in damage. The tsunami caused the most damage in the coastal …
Follow official evacuation orders: When a tsunami warning is issued, listen to local authorities and immediately evacuate to higher ground. Find high ground: If possible, move to the highest ground possible. Climb to the top of a hill or mountain, or seek shelter in a tall building. Stay away from the coast: Move at least …
Seismographs are instruments that measure and record seismic waves, which are waves of energy that travel through the Earth caused by movements of the Earth’s crust. Seismographs measure the amplitude, frequency and direction of the seismic waves. The data recorded by seismographs is used to study earthquakes, and to monitor large-scale earth movements.
Seismic waves are waves of energy that travel through the Earth’s crust and are caused by sudden disturbances, such as earthquakes. These waves can be detected by seismometers and are used to measure the magnitude and location of an earthquake. Tsunamis, on the other hand, are huge waves created by earthquakes, volcanic eruptions, and other …

Sonar is a technology used to detect and track underwater objects such as submarines, ships, fish, and whales. It uses sound waves to create a picture of the underwater environment. Sonar is also used to measure ocean depths. Sonar is an acronym for Sound Navigation and Ranging.
