what is gravity?Does only earth have gravity?
Gravity is a fundamental force that exists throughout the universe. It is the force that attracts objects with mass towards each other. It is what keeps us grounded on Earth and is responsible for the motion of planets, stars, and galaxies.
No, gravity is not exclusive to Earth. Every object with mass, regardless of its size, has gravity. However, the strength of gravity depends on the mass of the object. So, larger objects like planets and stars have stronger gravitational pulls compared to smaller objects.
For example, the gravity on Earth is stronger compared to the gravity on the Moon because Earth is much more massive. The gravity on the Moon is about 1/6th of Earth's gravity, which is why astronauts can jump higher on the Moon.
Similarly, the gravity on other planets in our solar system varies due to differences in their mass. For instance, Jupiter, the largest planet, has a stronger gravitational pull compared to Mars, a smaller planet.
In summary, gravity is a force that exists everywhere in the universe, not just on Earth. The strength of gravity depends on the mass of the object, with larger objects having stronger gravitational pulls.

The five themes of geography are Location, Place, Human-Environment Interaction, Movement, and Region. One of the options given in the question is not part of the five themes. The option that is not part of the five themes is Anthropology.
Explanation:The five themes of geography are Location, Place, Human-Environment Interaction, Movement, and Region. Therefore, one of the options given in the question is not one of the five themes of geography. To determine which option is not part of the five themes, you need to review each option and compare it to the themes to see if it aligns or not.
Anthropology: Anthropology is not one of the five themes of geography. Anthropology is the study of human societies and cultures, whereas geography focuses on the Earth's physical features, climate, and spatial relationships.
Physical Geography: Physical Geography is one of the five themes of geography. It examines natural features such as landforms, climate, ecosystems, and natural disasters.Location: Location is one of the five themes of geography. It refers to the position of a place on Earth's surface, including its absolute location (latitude and longitude) and relative location (in relation to other places).Human-Environment Interaction: Human-Environment Interaction is one of the five themes of geography. It explores how humans interact with their environment, including how they modify it and adapt to it.Region: Region is one of the five themes of geography. It categorizes areas based on common characteristics, such as physical features, culture, language, or political boundaries.Learn more about themes of geography here:https://brainly.com/question/19241468

a. the congo rainforest
b. the african mangroves
c. the serengeti grasslands
d. the sahel
Answer:
b.the african mangroves
it's correct on edge!
Explanation:
The ecosystem that best fits the characteristics described below is the African mangroves. Thus, the correct option for this question is B.
What is an Ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with each other for the purpose of food, space, and mating partner.
Large numbers of predators are not significantly found in the ecosystem like grasslands. So, option C is eliminated. The Sahel is the region in North Africa that mediates the transition between the Sahara and Sudanian savanna. So, option D is also eliminated.
The existence of Acacia trees and grasses is the characteristic feature of African mangroves. So, option A is also eliminated.
Therefore, the African mangrove is the ecosystem that best fits the characteristics described in the question.

Identify all of the different observations alfred wegener used to support his theory of continental drift.
Final answer:
Alfred Wegener proposed the theory of continental drift supported by evidence such as the fit of continental coasts, fossil records, similar rock formations, paleoclimate evidence, and stratigraphy, but his theory was not immediately accepted until the plate tectonics theory emerged.
Explanation:
The German scientist, Alfred Wegener, proposed the theory of continental drift in the early 20th century, supporting it with multiple lines of evidence. Wegener's theory suggests that all the Earth's continents were once united in a single supercontinent called Pangaea about 225 million years ago. The evidence he compiled includes:
The jigsaw puzzle fit of the continents, especially the eastern coastline of South America and the western coastline of Africa.
Similarity of fossil records across continents that are now widely separated by oceans, such as the fossil remains of the mesosaur in both South America and Africa.
The presence of similar rock formations and mountain ranges on continents separated by vast oceans, indicating they were once joined.
Paleoclimate evidence, such as glacial deposits in tropical regions, suggesting radical shifts in climate due to continental movement.
Stratigraphy that showed the same sequence of rock layers across different continents.
Despite the compelling evidence, Wegener's theory of continental drift was not immediately accepted by the scientific community, largely because he could not identify a mechanism for the movement of continents. It was not until the development of plate tectonics theory in the 1960s that Wegener's ideas were fully vindicated.
Where might you expect to find the greatest variety of kinds of marine organisms?

Most of the marine organisms are expected to be found in the shallow waters of the Caribbean Sea. The shallow waters are favorable for the survival of the organism. The shallow waters are warmer since then rays of the sun can easily penetrates and thus favoring the survivor of many organisms.
Volcanic ash is a good geologic time maker because the ash
Volcanic ash is a powerful geologic time marker due to its widespread dispersion during eruptions, unique chemical signature, and the ability to date it accurately, which aids in correlating and synchronizing geological and historical events.
Volcanic ash is an excellent geologic time marker because it consists of fragments of rock, minerals, and volcanic glass ejected during volcanic eruptions. These fragments, which measure less than 2 mm in diameter, are spread over wide areas by the force of the eruption and wind patterns, settling as layers that can blanket landscapes and ocean floors. Due to their unique chemical signature, these ash deposits can be precisely dated using various radiometric dating techniques.
This provides a chronological layer that can be correlated to other regions, enabling scientists to synchronize events and processes in Earth's history. When cultural materials such as artefacts or fossil remains are found in association with the volcanic ash layers, they too can be dated with a reasonable degree of accuracy. Thus, volcanic ash becomes a key tool for understanding the timing of geological events, human activity, and changes in the environment.

which of the following is a true statement about hurricanes?
A. they only affect tropical areas
B. they cannot be measered on any scientific scale
C. their winds always top 117 kilometers per hour
D. they cause more deaths every year than tornadoes and earthquakes
Hurricanes can affect both tropical and non-tropical areas, and their winds can exceed 117 kilometers per hour. They can be measured on scientific scales. However, the statement that hurricanes cause more deaths every year than tornadoes and earthquakes is not accurate.
Explanation:Hurricanes are storm systems characterized by low-pressure centers, strong winds, and heavy rains. They develop over warm ocean waters and rotate in a cyclonic pattern. They can affect both tropical and non-tropical areas, and their winds can exceed 117 kilometers per hour.
Additionally, hurricanes can be measured on scientific scales, such as the Saffir-Simpson Hurricane Wind Scale, which categorizes hurricanes based on their wind speeds. While hurricanes can be dangerous, it is not accurate to say that they cause more deaths every year than tornadoes and earthquakes, as the impact of these natural disasters can vary depending on various factors.

Options:
A. broadcasting
B. top dressing
C. band application
D. foliar feeding
Answer:
D. Foliar Feeding
