How can wind and water change the materials on earth's surface? (Specifically, rocks/the geophere) ​

Answers

When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. ... When layers of eroded material pile up, it's called deposition. This can create new landforms.

The local newspaper has published the passage below.

Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.

Which statement in the news passage above is inaccurate?

The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis is known as the northern lights.

Answers

#6: The living organisms in an ecosystem can be divided into three categories: producers, consumers and decomposers. They are all important parts of an ecosystem.

#7: Nature has its own recycling system: a group of organisms called decomposers. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth's cleanup crew

Almost no population actually reaches biotic potential instead it reaches its carrying capacity, carrying capacity is the largest number of individuals of one species that an ecosystem can support over time. Limiting factors determine the carrying capacity for an area. If there weren’t any limiting factors in an ecosystem, populations would keep growing. When they keep growing they eventually reach their biotic potential. Biotic potential is the potential growth that a population could grow in perfect conditions

Answer the following questions with a picture only PLEASEEEEE.

1. What is the main source of energy for ecosystems?

2. What are some natural things that can disturb ecosystems?

Answers

Answer:

1.Photosynthesis is the process of converting light into energy

2.Natural events, such as wind, drought, flood, fire, or disease.

Explanation:

1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.

2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

Disease can reduce the size of a population quickly.

The amount of resources, such as food and water, limit how many pikas can survive.

The presence of predators limits how large the population can grow.

As the population grows, the pikas compete with each other for resources.

The amount and types of space avalible in an environment mean only a certain number of pikas can make homes.
