The first light bulb was developed in the
Late 19th century
*but many concepts about electricity were known before 1800s.
Major concepts of molecular biology were developed in the
20th century
The earliest concepts about atoms were developed where? And when?
India and Greece more than 2500 years ago
Nuclear reactor does not produce carbon dioxide.
True or false
True
Exosphere
Is the outermost layer of the atmosphere
Thermosphere is
The heat layer of the atmosphere
*but you will be very cold because it’s not enough gas molecules to transfer the heat to you.
Mesosphere is
The middle highest layer of the atmosphere in which the gases are mixed.
Stratosphere is above the ozone layer
Natural gases filters out the suns UV radiation
Troposphere is known as the
Bad layer, has air pollution that is harmful to breath in
*It’s the closest to the earth’s surface
Water pollution
Contaminated water due to human activity
Ex: global warming, deforestation, industry livestock farming, fecal water dumping
Acid rain
Due to human activity
Ex: burning fossil fuels, manufacturing, oil refineries, cars releasing sulfur and nitrogen.
*Volcanic eruptions can cause acid rain naturally
Plate tectonics
Movement of plates produce earthquakes ,volcano, mountain ranges, ocean trenches
Gas pressure
Force of gas colliding with the walls of Its container
Divergent plate boundary
Plates rip apart
Convergent plate boundary
One plate dives beneath the other one
Transform plate boundary
Plates slides pass one another
