Answer:
Every organisms on the planet requires a specific environmental conditions for its growth and survival. If the environmental condition is favorable, the organisms grow fast and if the conditions are not suitable so it adversely affected the organisms. For example, plants grow best at the temperature between 25 to 40 Celsius. If the temperature goes below 25 or above 40, the growth decrease and sometimes the plant dies. So climate and abiotic factors such as temperature, humidity, light intensity etc has a great impact on the organisms.
Hypothesis: If plants are placed in white light, then the will grow better than plants in other colours of light.
Independent variable: Colour of light.
Dependent variable: plant growth.
Control group: the plant in the closet.
Experimental group: the plant is the other light colours.
Constants: miracle grow and amount of water.
Measurements: height of plants.
Answer:
B. The tropospheric gases move becuase of convection currents.
Explanation:
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.
