It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences

Answers

Answer:

Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.

Explanation:

Answer:

Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.

During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.

One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.

The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.

How would antelopes be affected if they cannot find enough plant matter to eat?

PLEASE IN 10 MINUTES!!

Answers

Answer:

Explanation:

Most antelopes are herbivores which means they eat only plants. If they cannot find enough plant matter to eat, slowly, the population in a herd of antelopes would go down from the lack of nutrients and energy they need from the food they eat(vegetation).

Antelopes is an animal that has large stomach for storing food so if it comes to a condition where there is no enough plant material for the antelope to eat it will start using the stored food for survival the stored food will be converted to energy

1. Using a glass when brushing teeth -
2. Hanging clothes -
3. Walking -
4. Feeding the stray animals -
5. Using back page of paper -
6. Using fan -
7. Watering the plants -
8. Sweeping -

Answers

Conserving our natural resources is crucial for the long-term sustainability of our planet and the well-being of future generations. Engaging in activities that promote conservation helps minimize our ecological footprint and protect the delicate balance of the Earth's ecosystems. Let's explore the reasons behind each of the activities you mentioned:

1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.

2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.

3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.

4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.

5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.

6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.

7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.

8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.

Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.
D.
Some of the water will evaporate on winter days but not on summer days.

Answers

The rate of evaporation of water from an open container is dependent on various factors, one of which is solar energy. The more solar energy present, the more water will evaporate. Therefore, the students can predict that less water will remain in the container after one day in summer than after one day in winter. Hence, the answer is option B. We can also explain why option A, C, and D are incorrect. Option A is incorrect because the amount of solar energy present is different in different seasons. Hence, the rate of evaporation will be different, and so the amounts of water evaporated will not be equal on summer and winter days. Option C is incorrect because it is the opposite of the correct answer. Option D is also incorrect because water will still evaporate in winter despite less solar energy being present.

C That’s the Right answer

How does the orientation of the North Pole change during the year?

The orientation of the North Pole remains relatively fixed throughout the year. It does not change its position or direction.

The North Pole always points in the same direction in the northern sky, which is towards the North Star or Polaris.

However, the tilt of the Earth's axis in relation to its orbit around the Sun causes the amount of sunlight received by different parts of the Earth to vary throughout the year.

By adding tape to his BAAD, Cramwood increased its mass and increased

What is inertia?

Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.

In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.

The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.
