b. false
It is likely that man had a knowledge of agriculture since his creation is True
Different regions of the world saw the autonomous emergence of agriculture, which involved a wide variety of species. There were at least eleven different Old and New World locations that were engaged as independent sites of origin. Around 12,000 years ago, agriculture began to take root, altering human behavior. They transitioned from a nomadic hunter-gatherer way of life to farming and permanent communities.
In South America, agriculture started as early as 9000 BC with the cultivation of a number of plant species that ultimately developed only into minor crops. Between 8000 BC and 5000 BC, the potato was domesticated in the Andes of South America, along with beans, squash, tomatoes, peanuts, coca, llamas, alpacas, and guinea pigs.

Answer:
how do you store water at home
ans:Water should be stored in a cool, dark place away from direct sunlight.
During winter, what is the most likely temperature of the water at the bottom of lake superior in the northern united states?
During an adiabatic process, the temperature will _____ as the air parcel _____ and _____.
During an adiabatic system, the temperature will lower as the air parcel condenses and heat is launched.
In widespread, as a parcel of air rises, the water vapor in it condenses and heat is launched. The rising air will therefore cool greater slowly because it rises; the wet adiabatic lapse charge will in trendy be much less negative than the dry adiabatic lapse fee.
An adiabatic technique is described as a procedure wherein no heat transfer takes region. this doesn't imply that the temperature is regular, however instead that no warmth is transferred into or out of the gadget.
While thinking about an adiabatic manner a growing parcel of air usually cools. If it's far unsaturated it cools on the dry adiabatic lapse fee (10 C/km). If it's far saturated it cools at the dry adiabatic lapse rate minus the amount of heat delivered due to latent heat launch of condensation.
Adiabatic technique = no trade of heat with the surroundings. A growing parcel of air expands due to the fact that air stress falls with elevation. This growth reasons the air to cool.

What is the apparent relationship between a stream’s gradient and its sinuosity?
Answer:
Explanation: The higher the gradient, the faster the stream flows. Channel shape and texture. The shape and roughness of the channel also affect the velocity of the flowing water.
The apparent relationship between a stream's gradient and its sinuosity is that they are often inversely related. In other words, as the stream's gradient decreases, its sinuosity tends to increase, and vice versa.
1. **Gradient:** The gradient of a stream refers to the change in elevation of the streambed over a certain distance. It is often expressed as the vertical drop in elevation per unit of horizontal distance (e.g., feet per mile or meters per kilometer). A steeper gradient indicates a faster flow of water, and the stream is likely to be more erosive, creating a straighter path.
2. **Sinuosity:** Sinuosity is a measure of how much a stream meanders or curves along its course. It is calculated as the ratio of the length of the stream channel to the straight-line distance between its endpoints. A higher sinuosity indicates a more meandering or winding stream course.
The relationship between gradient and sinuosity can be explained by the processes of erosion and sediment transport within a stream:
- **High Gradient and Low Sinuosity:** In streams with a high gradient (steep slope), the water flows more quickly and with greater energy. This higher energy leads to more erosion, which tends to create a straighter channel. The stream has less time to meander because the erosive force is powerful enough to maintain a relatively direct course.
- **Low Gradient and High Sinuosity:** On the other hand, when the stream's gradient is low (gentle slope), the water flows more slowly and with less energy. This slower flow allows sediment to accumulate along the sides of the stream channel, promoting meandering. The stream's energy is not sufficient to erode these deposits, so the watercourse tends to develop curves and bends.

The ______ is like a slow-moving river of molten rock that the crust, broken into different plates, moves on top of.
The asthenosphere is like a slow-moving river of molten rock that the crust, broken into different plates, moves on top of.
The asthenosphere is the denser, weaker layer below the lithospheric mantle. It lies between about one hundred kilometers (62 miles) and 410 kilometers (255 miles) under Earth's surface. The temperature and pressure of the asthenosphere are so excessive that rocks soften and partly melt, turning into semi-molten.
The Asthenosphere is made of semi-plastic rock. For the reason that Lithosphere has a lower density, it floats on top of the Asthenosphere much like the manner wherein an iceberg or a block of wood floats on water. The decreased mantle beneath the Asthenosphere is more rigid and less plastic. Under the Mantle is the outer core.
Asthenosphere may go with the flow like a liquid, destroy like a stable, and transmits seismic waves at different rates to the other layers. It may even be liable for earthquakes and volcanic eruptions. The asthenosphere sits underneath the lithosphere and forms a part of the top mantle.

How does flooding rice fields reduce the need for herbicides and pesticides in rice farming? a. while rice has a submerged growth state, most weeds and pests do not. b. flooding the fields causes the soil to degrade so weeds cannot take root. c. residual herbicides and pesticides from previous seasons dissolve in the water. d. all of the above please select the best answer from the choices provided a b c d
The Correct Answer : Flooding the fields causes the soil to degrade so weeds cannot take root.
Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.
What is Pesticides?Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others. These chemicals can work by ingestion or by touch and death may occur immediately or over a long period of time.
What is Herbicides?Herbicides are used to kill undesirable plants or “weeds”. Some herbicides will kill all the plants they touch, while others are designed to target one species.

The geographical knowledge that the white elites had but the salves did not was that of maps, scale, ordinal directions and distance.
The white elites' "deliberate strategy" regarding slaves' geographical intelligence was limiting their geographical intelligence. This way they were able to capture the slaves, both in their mental as well as physical spheres, leaving no scope of escape for them.

What would happen if water infultrated to the depths of the clay lens at point a:______.
Infiltration would happen if water infultrated to the depths of the clay lens at point .
Cavitation is the movement of water through the soil. Eventually, as water seeps into the deeper layers of the soil, it reaches aquifers, i.e. water below the surface. The upper surface of this aquifer is called the "groundwater".
Infiltration occurs when water seeps into the ground from the ground. It moves underground and moves between soil and rock. Part of the water will be absorbed by the roots to help the plant grow. The leaves of the plant will eventually release water into the air through the plant and out as waste.
The process by which water seeps into the ground to become groundwater is called groundwater recharge. The area on the surface where water infiltrates is called the recharge area.
