surface currents flow in the northern hemisphere and in the southern hemisphere.
Surface currents generally move in the same direction as the winds that created them. However, because of Coriolis deflection, the surface currents are offset approximately 45 degree relative to the wind direction; 45 degree to the right in the Northern Hemisphere, and left in the Southern Hemisphere.
What are the flow of currents in the northern and southern hemispheres?The constant flow of water in the ocean is known as an ocean current. Numerous factors, such as temperature, salinity, wind, water density, and gravitational attraction, can generate these currents. The Coriolis Effect, which results from the Earth's rotation, causes currents to flow counter-clockwise in the southern hemisphere and clockwise in the northern hemisphere. Ocean current has a significant impact on the climate. In some places, warm water from the equator is transported to a colder location, making the latter warmer. For instance: With the help of the California Current, an eastern boundary current that transports northern waters southward, the waters off California's coast are kept cooler than those along the east coast of the United States, where similar latitudes are found.

two populations of birds with somewhat different coloration live on opposite sides of a peninsula. the habitat between the populations is not suitable for these birds. workers at a bird sanctuary have found that when birds from the two populations are brought together at the sanctuary, they produce young whose appearance is intermediate between the two parents. these offspring will successfully breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees.
Habitat isolation keeps the two populations separate. Habitat isolation occurs when differences in habitat preferences reduce the likelihood of mating between individuals associated with different habitats.
Habitat isolation occurs when two species, or would-be species, reside simultaneously in the same location and not in the same location at the same time, i.e., occupying distinct aspects of the same place and so not coming into contact with each other.
For example, if two populations of flies exist in the same geographical area, but one group lives in the soil and the other on the surface of the water, members of the two groups are very unlikely to meet and reproduce.

The diagrams below show the crystals of four different rocks viewed through the same hand lens. Which crystals most likely formed from molten material that cooled and solidified most rapidly?
The crystal most likely formed from molten material that cooled and solidified most rapidly is option 4.
Igneous rocks or crystals are formed when hot, molten material cools down crystallize and solidifies. The melted material originates deep within the Earth near active plate boundaries or hot spots, which rise toward the surface where they form igneous rocks. Igneous rocks are divided into two groups, intrusive igneous rocks, or extrusive igneous rocks, depending upon where the molten rock solidifies. Extrusive igneous rocks, also called volcanic igneous rocks, are created when magma exits and cools above or very near the Earth's surface. Intrusive igneous rocks are created when magma cools underneath the Earth’s surface. The texture of crystals can be crudely related to the rate of cooling. The higher the rate of cooling leads to smaller and finer texture of the crystals. The rate of cooling is proportional to the difference in temperature between the bodies in contact with heat flowing from the warmer body to the cooler body. Hence, option 4 is likely to form by the most rapid rate of cooling.

False. In controlled ecosystems like forests, pastures, or crops as well as in natural ecosystems, erosion causes numerous, severe harms.

Reduced soil's capacity to store nutrients and water is one of the effects of erosion on cropland. subsoil exposure, which frequently has undesirable physical and chemical characteristics. greater runoff rates, wasting water and nutrients that would have been used to cultivate crops. Runoff the initial damage to the land caused by the conversion of natural ecosystems to grazing land is less than that caused by crop cultivation, this change in land use may result in significant rates of erosion and loss of topsoil and nutrients. When there is less ground cover, erosion and compaction are made possible. Only after the surface storage capacity has been reached may runoff start.
