Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift?

A. The continents drifted apart due to repeated meteor impacts.
B. The continents were once connected as one landmass.
C. The continents have moved apart very quickly due to earthquakes.
D. The continents are magnetically pulled toward or pushed away from one another.

Answers

Answer:

Option B

The continents were once connected as one landmass.

Explanation:

The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.

The most appropriate option that shows this is option B: The continents were once connected as one landmass.

This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface

The statement that describes one of Wegener’s ideas that contributed to the theory of continental drift is the continents were once connected as one landmass. The correct option is B.

What is continental drift?

Continental drift theory states that the motion of the earth results from the movement of tectonic plates. The theory tells that the different continents were fitting together.

According to the theory of continental drift, the world's continents were once joined together to form a supercontinent. However, because to some underlying earth factors, they gradually drifted apart over time.

According to one of Alfred Wegener's theories, the continents were previously linked together as a landlocked mass a very long time ago. The separation of the continents indicates that their positions on the surface of the globe are constantly altering.

Thus, the correct option is B. The continents were once connected as one landmass.

describe how the abiotic factors faced in the desert differ from those in the rainforest

Answers

Answer:

Deserts and rainforests have vastly different climates and rainfall. There is more water and sunlight in a rainforest than in a desert. etc.

Explanation:

Abiotic elements in a marine ecosystem would be salinity and ocean currents. Examples could be light, water, and temperature in a terrestrial habitat.

What are the different abiotic factors

The animals are suited to live in the circumstances of the environment in both deserts and tropical rainforests.

Because of the heavy rain in the tropical rainforests and the severe heat in the deserts, neither tropical rainforests nor deserts are habitable for people.

The desert has low biodiversity since there are so few living things there. There may be no living things and hence no biodiversity in some desert regions.

The rainforest, on the other hand, contains the most diversity of any biome on Earth.

Therefore, the abiotic factors faced in the desert differ from those in the rainforest.

Explanation:

if the phenotype increases the survival, then they are better adapted and will survive until reproductive age, when they reproduce, their genes are passed on and their offspring will have the same phenotype. this continues for many generations and the new phenotype will be common. ( this whole process is known as natural selection).

B - Reduced resources for native organisms.
C - Introducing new organisms ALWAYS benefits the native organisms in an ecosystem.
D - Reduced survival rates of native organisms.

Answers

Answer:

It should be D.

Explanation:

The invasive species will negatively effect the ecosystem and the natural predator in the area. Like the Blue Lobster problem in Maine.

A and B are effects that invasive species can have on an ecosystem.

What is an invasive species?

An invasive species is a species that is introduced to an ecosystem where it is not native and has a harmful impact on the environment, the economy, or human health.

These species are often highly adaptable and can outcompete native species for resources, leading to reduced survival rates and changes in the balance of the ecosystem. Invasive species can also cause indirect harm by disrupting food webs and changing the abundance of other species. Human activities, such as trade and travel, are the primary causes of the spread of invasive species. In order to prevent further harm, efforts are made to control and manage populations of invasive species and to prevent their spread to new areas.
