What is similar about the desert and savanna zones in Africa?

Both contain stone plateaus.
Both experience limited rainfall.
Both contain abundant grasslands.
Both experience high temperatures.

please choose from above

Answers

Answer:

Both experience limited rainfall.

Explanation:

no water

The similarity between desert and savanna zones in Africa is both have high temperatures. Thus, the correct answer is option D.

What are savanna zones?

A savanna, also known as a savannah, is a mixed woodland-grassland ecosystem distinguished by trees that are sufficiently spaced so that the canopy does not close. The open canopy allows enough light to reach the ground to support an unbroken herbaceous layer dominated by grasses.

Despite their dense tree cover, savannas have an open canopy. Savannas are commonly thought to have widely spaced, scattered trees. However, tree densities are higher and trees are more regularly spaced in many savannas than in forests. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season.

Therefore, both experience high temperatures.

explain why mantle convection occurs

Answers

Answer:

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. [1] [2] The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle .

Explanation:

The mantle is heated from below (by the core), and in hotter parts, it rises (is buoyant), whereas in colder areas, it sinks.Convection cells are created as a result, which causes mantle material to move horizontally near the Earth's surface.

Mantle convection occurs for what reason?

Because relatively hot rocks are less dense and rise in a gravitational field while relatively cold rocks are denser and sink, mantle convection happens.When hot rocks rise, heat is advected upward, and when cold rocks fall, cold is advected downward; this counter flow is the same as an upward heat flux. Several tectonic plates that make up the lithosphere are continuously being generated or eaten at plate borders.As mantle is added to a plate's expanding boundaries, which is related to the spreading of the seafloor, accretion takes place.The rising element of mantle convection is up welling beneath the spreading centers. When highly heated particles in a liquid or gas move and replace less heated particles, convection takes place.Convection is the process through which heat energy is moved from heated areas to colder ones.When heated, gases and liquids both expand .A convection cell cannot form without a heat source.The heat source warms the fluid, which is then pushed away.The fluid inevitably cools after starting to lose heat.The flow of newly heated matter drives this colder, denser matter back toward the initial heat source. Convection, a thermally driven process whereby deep heating causes material to expand and become less dense, leading it to rise while being replaced by complementary cool material that sinks, is the primary method of heat transport in the Earth's mantle. Any fluid, including boiling water, soup (where the cells may be recognized by the particles they transport, like as rice grains), the ocean, or the surface of the Sun, can produce convection cells, also known as Hadley cells. Convection causes the water at the bottom to expand and become lighter when water is heated.The cooler molecules then sink to the bottom as the heated ones rise to the top.Then, these colder molecules warm up. Convection is the process of warm fluid continuously rising above cold fluid.For instance, if you heat a bucket of water and dip your hand into it before removing half of it, the other hand will indicate that the water is chilly.Convection is the cause of this .The difference in temperature between the two fluid components allows the heat energy to be transported by convection.Hot fluids have a tendency to ascend while cold fluids have a tendency to sink due to this temperature differential.Convection current is produced as a result within the fluid. These currents receive their heat from both the mantle and the Earth's core.Mantle material rises slowly through the asthenosphere in the form of hot columns.The hot material expands out and pushes the colder stuff out of the way near the top of the asthenosphere. The commonly accepted, oversimplified theory for why tectonic plates move is that they are propelled by currents in the upper mantle, the slowly flowing layer of rock just beneath the Earth's crust.Colliding currents cause plates to collide.Currents that diverge pull them apart. Mantle convection is the term used to explain how the mantle moves when heat is transferred from the blazing core to the brittle lithosphere.The mantle's temperature gradually drops over extended periods of time as a result of below- and above-surface heating and cooling.

Casual walkers in rural and urban areas in Alberta may enjoy the vibrant purple flowers of the purple loosestrife plant, but the trained eye of an ecologist sees the threat this invasive species poses.Purple Loosestrife InvasionPurple loosestrife was not always seen in and around Alberta. In fact, it wasnt found anywhere in North America before the 1800s.During the 1800s, ships transporting goods around the world were sometimes without cargo for a time, particularly when they were heading to collect a new load. Wooden ships dont balance well when they are empty, so when they were without a cargo, they were often filled with ballast instead.How does this relate to purple loosestrife in Alberta? Well, purple loosestrife is a naturally-occurring plant in Europe and Asia, which means that their seeds may become mixed in with the soils found there. Ships sailing from Europe and Asia to North America without cargo often used soil as ballast to maintain the balance of the ships, and then dumped the soil when they arrived to pick up their cargo. It is believed that this dumped soil introduced the purple loosestrife species to Canada.It may also be the case that early settlers brought purple loosestrife with them when they settled Canadas west.Purple Loosestrife: A Not-So-Welcome IntroductionSo whats the big deal about having purple loosestrife in Alberta? Well, purple loosestrife is not a species of plant that occurs naturally in the province- it is an introduced species. Organisms that dont occur naturally in an area but are instead brought from elsewhere are categorized as introduced species.Again, whats the big deal about that? Well, organisms that are introduced to an ecosystem may become invasive - think: invader! An invasive species is defined as any organism that reproduces so quickly or grows so aggressively that it becomes a problem for the other organisms around it. Invasive plant species tend to outcompete local plants for resources such as sunlight, water and root space. In this way, invasive species can harm ecosystems by taking over, disrupting food webs and decreasing biodiversity.Purple loosestrife has invaded local wetlands and is often found growing unchecked in other wet areas of the city. It flowers prolifically, producing millions of seeds each year. These seeds have many vectors of dispersal, for example, they may be blown to new places by the wind (aerochory), travel along with moving water (hydrochory), hitchhike in animals fur or be deposited in animal waste (zoochory), and even planted intentionally by humans.Purple Loosestrife: Super-plant!Purple loosestrife grows in clumps with a dense root system that extends underground like a living mat - its like a super villain, soaking up nutrients and taking over the space where other plants might grow. In wetlands, waterflow can be disrupted as waterways become clogged.Over time, purple loosestrife becomes the dominant plant in an area and other plants disappear. This disrupts the food web because animals that only feed on the plants that disappear, disappear too. Once a plant disappears and the animals that feed on that plant disappear, there is a ripple effect along the food chain. Animals that can adapt to their food source disappearing by switching to a different food source will survive, but those that dont adapt either move to a different habitat or die.Waging War on Purple LoosestrifeIn Alberta, purple loosestrife is classified as prohibited noxious, which means that it is not allowed to be planted and any plants that are found must be destroyed. In many Alberta cities, crews are sent out to dig out and destroy clumps of loosestrife that are reported.Another way that purple loosestrife has been kept in check across Canada is through the use of biological controls (when one living organism is used to control another). Beetles such as the black-margined loosestrife beetle feed on purple loosestrife, so they are the plants natural enemies - perfect for biological control. Releasing the black-margined loosestrife beetle can reduce the purple loosestrife population in an area significantly. When an invasive species is controlled, often the original plants can re-populate and the ecosystem can return to a balanced state.Using Text Features to Predict InformationScan the nonfiction text to find the text features listed.
