Answer: the sun
Explanation:
The sun's radiant energy reaches the earth's surface either directly through radiation, indirectly through convection, or it can move "across" or "through" objects or materials on the surface via conduction. Let's look more closely at each case. We've probably experienced the feeling of "warmth" of the sun on our skin on a sunny day. Light energy from the sun is reaching us across space and down through the atmosphere through radiation. A dark colored vehicle in the sun quickly becomes warm (or hot!) to the touch because of radiation. The light energy from the sun heats the air in the earth's atmosphere, and this drives convection and transfers thermal energy around. It is possible that we've felt a "hot breeze" on our skin on sunny days. The thermal energy in the air will be carried to objects in its path, and it will warm them.
Answer:
90m/h N
Explanation:
we consider janes velocity to the positive X axis so Vj=280km/s
and the final position a dot in on the graph r=294km, we find the x and y components:
294*cos(17.8)=280 X+ confirming our theory
294*sin(17.8)=90 Y+ or N and that's the winds' velocity.
Answer:
A
Explanation:
Because both the elements are non-metals
Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
With the earth’s current rotation, the major pressure systems of the general circulation can be correlated with the increase and decrease of air. When there is a considerable amount of air, precipitation will become present on a large scale. When there is less air, then there is an increase in chances of an area becoming dry. According to our textbook, a decrease in air on the eastern margin (west coast) creates a subsidence inversion. This causes dry weather. On the western margin (east coast) the humidity in the air rises, condenses and creates rain fall. So if the earth were to rotate in the opposite direction, we could possibly expect weather on the west coast to produce more rain and the weather on the east coastto become dry.
