The Earth comprises many spheres of subsystems, which associate with each other to develop a composite and spontaneously changing system of the Earth. The processes taking place in the system of the Earth occurs on spatial scales changing from fractions of millimeters to thousands of kilometers, and on time scales, which varies from milliseconds to billions of years.
The examples of instantaneous scales are a rotation of the Earth, breathing, an earthquake.
The examples of long-term scales are making coal and plate tectonics.
The system of the Earth is featured by various overlapping cycles in which matter is recycled again and again. The cycles involve interactions between multiple spheres and systems. The examples of cycles are rock cycle, day and night, and seasons.
Volcanoes discharge a huge concentration of particulate matter into the atmosphere. These particles function as nuclei for the development of droplets of water (hydrosphere). The rainfall, that is, hydrosphere usually upsurges after an eruption, initiating growth of the plant (biosphere). Thus, volcanoes and volcanic activities are a good illustration of system interactions.
Answer:
determining hereditary diseases in individuals and families
Explanation:
DNA technology is used to join together DNA segments. DNA technology includes DNA sequencing and DNA cloning.
DNA technology is important to the pharmaceutical industry. By genetic modifications such as high nutrition value, it helps in improving the food production quality.
DNA technology helps in determining hereditary diseases in individuals and families.
The green house effect refers to gases trapping the heat energy reflected from earth’s surface.
gases trapping heat energy reflected from the earth's surface.
<u>Explanation:</u>
It is the greenhouse effect that made earth a planet that supports life. if there was no green house effect the earth would have been too cold to live on. Sunlight contains rays like UV and infrared.
UV rays being harmful are blocked by the ozone layer in the stratosphere. Infrared rays that enter the earth’s atmosphere are trapped by the greenhouse gases like carbon dioxide, water vapour, methane etc. the trapped infrared rays help in providing warmth.
Answer:
Increase in kinetic energy of the gases
Explanation:
The direct sunlight will heat up the molecules making up the gases in the balloon.
Kinetic energy resulting from the heating of these particles will make them become randomized. They then begin to move more haphazardly colliding vigorously with themselves and the wall of balloon.
According to Charles's law "the volume of a fixed mass of gas is directly proportional to its temperature provided pressure remains constant" .
The sunlight heats the balloon and causes a rise in temperature. This will make the gas volume to increase and the balloon expands.
