Dark Matter only: detected through its gravitational attraction, has mass, most common form of mass in the halo of the Milky Way Galaxy, likely to consist of subatomic particles
Dark Energy only: inferred to exist from the measured acceleration of the universe's expansion, the proposed source of a universal repulsive force
BOTH: the universe contains more of this than it contains matter made from atoms, we do not know what it is made of
NEITHER: blocks light from stars behind it, "dark" because it emits only infrared light
Changes in the moon's visibility.
Answer:
Explanation:
the motion of surface winds in the Northern hemisphere on Earth due to the uneven heating of the atmosphere and Coriolis force. Due to the Earth's rotation, surface winds have different speeds at different latitudes as follows:
Surface winds travel faster closer to the equator (0 degrees latitude).
Surface winds travel slower closer to the North pole (90 degrees latitude).
temperature, humidity, and precipitation
Why Farmland is Abandoned:
As groundwater pumping increased, water tables dropped, requiring pumping from deeper levels and at greater costs. Because of the increased cost, irrigation became prohibitively expensive. Farms thus were abandoned as unprofitable, especially in Cochise and Pinal counties.
