The atoms and molecules that make up substances are always in motion. What happens when heat or thermal energy is added to a substance?
the particles move faster
the particle movement doesn't change
the particles move slower
the particles stop moving
Answer:
the particles move faster
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Answer:
the particles move faster
Explanation:
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.
Please give the correct answer

Which of the following is an example of ecological succession?
A
New trees are now providing constant shade, and plants around them that needed sun to survive are being overgrown by shade-dependent shrubbery.
B
Marigolds and sunflowers are planted every year in a flower bed. Both flourish for a few months and then die off at the end of the season.
C
Every spring buds appear on the trees, then they turn into leaves. In the fall, these leaves change colors and die and eventually fall off the trees.
D
Tomato plants growing in a pot are replanted into the ground next to basil and other herbs. All of the plants flourish.
Ecological succession is demonstrated by the fact that nearby plants that need sunlight to flourish are now being supplanted by vegetation that requires shade. So, the correct option is A.
What is an Ecological succession?Ecological succession is the process of change in an ecological community's species composition over time. The time frame can be many decades or less or more. The cycling of nutrients like carbon, nitrogen, and sulphur is made possible by bacteria.
Ecological succession is the progressive change that occurs in a species through time as a result of the environment. Given that all biotic elements must adapt to changes in our environment, this change is both predictable and unavoidable.
The completion of this process will bring the ecosystem to equilibrium. A climax community is the one that succeeds in achieving this goal. Some species multiply in an effort to reach this balance, while others decline.
Therefore, the correct option is A.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
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.

Answer: Scientific questions are those questions that can be answered through observation of world around us and by experimentation.
Explanation:
The scientific questions related to the earth and the space science are as follows:
1. How the celestial bodies like moon, sun, and others affect the functioning of the earth?
2. How earth is different from other planets in the space?
3. What is the distance covered by the earth from other celestial bodies including other planets in the solar system?
4. How asteroids and meteors affect the earth?
5. Why different regions of the earth receive different intensities of light from the sun?
Explanation:
Ans1:-)Gravity is the force that connects every object - planet, the Sun, moons, asteriods, comets - to every other object. The Earth is constantly being tugged by all the other bodies in the solar system. Except for the Sun and the Moon, most bodies are either too small or too
Ans2:-)Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays. But many scientists agree our planet's most special feature might just be us. ... The fact that Earth hosts not just life, but intelligent life, makes it doubly unique
Ans3:-)For objects within the solar system, distances are calculated from their orbital parameters and are center to center distances. For objects outside of the solar system, those objects are so far away that there is no discernable difference between the center to center distance and the surface to surface distance.
Ans4:-)Such collisions could have caused the larger bodies to be broken up into the smaller objects we observe as meteorites. Much evidence suggests that the asteroids could be the parent bodies of meteorites.
Ans5:-)Because of the Earth's tilt the sun's rays strike the surface at a slant at the poles; they are less focused. ... The tilt of the Earth causes different areas to receive different amounts of solar energy. The difference in solar energy received at different latitudes drives atmospheric circulation.

Fossil Record Research You will choose a vertebrate animal from an aquatic ecosystem and a vertebrate organism from a terrestrial ecosystem. You will research the fossil record of each. You will analyze the fossil evidence and determine past organisms they are related to, how the fossil of the modern organism is similar to the past organisms, and how the organisms have changed over time. You should also look for relationships between the terrestrial and aquatic organisms. Questions to guide your research: ●What is the habitat for your organism like?
●What role does your organism play in the ecosystem?
● Is there evidence of relationships between aquatic organisms and terrestrial organisms?
● Does the fossil record show a possible relationship between aquatic organisms and terrestrial organisms?
● How did the organisms change over time?
Final product: You will construct an explanation about how your aquatic organism compares to the terrestrial organism. You need to also refer to possible connections in the fossil records of aquatic vertebrates and terrestrial vertebrates. Write in complete sentences.

Preservation of remains in amber or other substances is the rarest from of fossilization; this mechanism allows scientists to study the skin, hair, and organs of ancient creatures.
Permineralization, where minerals like silica fill the empty spaces of shells, is the most common form of fossilization.
Molds form when shells or bones dissolve, leaving behind an empty depression; a cast is then formed when the depression is filled by sediment.
Replacement occurs when the original shell or bone dissolves away and is replaced by a different mineral; when this occurs with permineralization, it is called petrification.
In compression, the most common form of fossilization of leaves and ferns, a dark imprint of the fossil remains.
Decay, chemical weathering, erosion, and predators are factors that deter fossilization.
Fossilization of soft body parts is rare, and hard parts are better preserved when buried.
Key Terms
amber: a hard, generally yellow to brown translucent fossil resin
permineralization: form of fossilization in which minerals are deposited in the pores of bone and similar hard animal parts
petrification: process by which organic material is converted into stone through the replacement of the original material and the filling of the original pore spaces with minerals

List 3 negative impacts does plastic pollution have on the ocean?
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.
