The three models below show the same amount of sunlight striking different parts of Earth's surface at different angles. Select the model that shows the part of Earth's surface that would heat up the least.
11 answers
Since I am unable to see the models, I am unable to select the correct model. However, generally speaking, the part of Earth's surface that would heat up the least would be the part that receives sunlight at a lower angle or is shaded.
The model below shows the Moon at one position in its orbit around Earth. The white half of the Moon represents the part of the Moon that is lit up by the Sun. Select the phase of the Moon shown in the model. (1 point) Responses Full moon Full moon Third Quarter moon Third Quarter moon New Moon New Moon 1st quarter moon 1st quarter moon
Since I am unable to see the model, I cannot determine the phase of the Moon shown. However, based on the options, if the white half of the Moon represents the part of the Moon that is lit up by the Sun, it is likely showing a Full Moon phase.
Which of the following is a key characteristic of all planets?(1 point) Responses They are made up of mostly ice and dust They are made up of mostly ice and dust They orbit the sun and shine by reflecting light They orbit the sun and shine by reflecting light They are small rocky objects the burn upon entering Earth's atmosphere They are small rocky objects the burn upon entering Earth's atmosphere They have a tail that extends as it moves through space They have a tail that extends as it moves through space
The correct response is: They orbit the sun and shine by reflecting light.
Which of the following best describes the role of gravity in the formation of planets, stars, and solar systems?(1 point) Responses Gravity causes the expansion of the universe. Gravity causes the expansion of the universe. Gravity prevents the formation of stars and planets. Gravity prevents the formation of stars and planets. Gravity brings together matter, leading to the formation of stars, planets, and solar systems. Gravity brings together matter, leading to
Gravity brings together matter, leading to the formation of stars, planets, and solar systems.
For each of the statements below, indicate whether the statement describes a scientific theory, a scientific law, or both. (1 point) Scientific Theory Scientific Law Both Can be modified if new evidence or information arises Scientific Theory – Can be modified if new evidence or information arises Scientific Law – Can be modified if new evidence or information arises Both – Can be modified if new evidence or information arises Often represented by a mathematical formula Scientific Theory – Often represented by a mathematical formula Scientific Law – Often represented by a mathematical formula Both – Often represented by a mathematical formula Explains how a natural phenomenon works Scientific Theory – Explains how a natural phenomenon works Scientific Law – Explains how a natural phenomenon works Both – Explains how a natural phenomenon works Describes a relationship that always occurs under specific conditions
Scientific Theory - Describes a relationship that always occurs under specific conditions
Scientific Law - Describes a relationship that always occurs under specific conditions
Both - Describes a relationship that always occurs under specific conditions
Explanation: A scientific theory can be modified if new evidence or information arises, while a scientific law cannot be modified. Both scientific theories and laws can be represented by mathematical formulas. Furthermore, both theories and laws explain how a natural phenomenon works. Finally, the statement that describes a relationship that always occurs under specific conditions pertains to both scientific theories and laws.
