<span>Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.</span>
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.
Answer:
Explanation:
Horses allowed Native Americans to travel to find food and other supplies. Horses also helped strengthen military power. Horses were not the only animals making a large impact on the Americas.
Answer:
Radius
Explanation:
Diameter is from one side of the circle to the other radis is from the middle point to the edge so a radius+radius will get you the diameter
Answer:
Earth's atmosphere is below 26 km is composed of 98%.
Explanation:
- Troposepher marks the boundary for most of the convective activity to take place on the surface of the earth's this place consist of 99% of the total space for the all-weather phenomenon to occur and as a result of which is considered to a homogeneous sphere.
- Here the water vapor, dust particles, and other gaseous bodies are found and thus this layer is a life-supporting layer full of oxygen and hence, comprise all biotic components like the plants, animal and man.
- Above this layer there are drastic changes in temperature with increasing height as the atmospheric pressure at higher altitudes decreases and so does the life-supporting layer, it can be noted that the layer that protects the earth i.e ozone is found in the mesosphere at an altitude of 30 kilometers.
- Rest most of the weather phenomenon takes place here as it sets the stage for weather patterns as convective currents coming from the equator can't pass this layer.
