Explain how the gradient, load, and discharge of a stream will affect erosion. Use details to support your answer PLS HELP
Answers
In the lower reaches of a stream, where the discharge is greater, since friction is less the stream need not be so steep to transport the load. If it were steeper than needed to transport the sediments erosion would result. But this would decrease the gradient leading to a decrease in erosion.
Which of the following best describes the likely impact of an invasive plant species on a warm ecosystem?
The invasive plant species become carnivores since their normal food source is eaten by the native producers. The invasive plant species eat other consumers in the ecosystem, causing a decrease in the consumer population of the ecosystem.

The invasive plant species become decomposers since the ecosystem already has native producers. All other decomposers go extinct in the ecosystem, replaced by invasive plant species.
Answers
Answer:
The best description of the likely impact of an invasive plant species on a warm ecosystem is:
The invasive plant species take over resources used by native plant species. Some plant species decrease in population, affecting the food source for consumers in the ecosystem.
Invasive plant species have the ability to outcompete native plant species for resources such as sunlight, water, and nutrients. This can lead to a decrease in the population of native plant species as they are unable to access sufficient resources to thrive. As a result, the food source for consumers in the ecosystem may be affected, leading to potential changes in the population dynamics of the consumer species.

What is an example of physiological adaptation?
(Give me a thanks and I will make you brainiest)
Answers
Answer:
An example of physiological adaptation is the development of a thicker fur coat in animals living in colder climates. This adaptation helps to insulate the animal and keep its body temperature regulated. Other examples of physiological adaptation include the ability of some animals to hibernate in winter, changes in the shape of feet and claws to allow better climbing, and changes in the shape of beaks to allow better feeding in different environments.

Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Fossil fuels are preserved remains of animals and plants. They record documents of diversity of life forms. Paleontologists are people who study about fossils.
What are fossils?Fossils are decomposed plants and animals. They can be the preserved remains or traces of living things. Thus the first statement is correct. The second statement that they record documents the diversity of life forms is correct since, by studying fossils we can find which types of living things were there in an area.
The people who study on fossils are called Paleontologists. The fossil formed when an animal walked in mud long ago and then the mud hardened into rock is an example of trace fossils. Most fossil are found in sedimentary rocks.
Fossils tell about both land and water plants and animals. A paleontologist finds a fossil of a fish on a mountain. She can infer that the area was once underwater. Not every but most dead animals and plants form fossils.

When people build houses and roads, they often pile up dirt or cut into the sides of hills. Predict how this might affect sediment on a slope. Explain how to control the effects of such activities.
Answers
The activities of building houses and roads can have a significant impact on sediment on a slope. When dirt is piled up or hills are cut into, it can cause erosion and destabilize the slope, leading to increased sediment runoff. To control the effects of such activities, it is important to use erosion control measures such as terracing, contour plowing, and the use of vegetation to stabilize the soil. Additionally, sediment basins and sediment traps can be used to capture and contain sediment runoff.
