Rocks become magnetic when(1 point)
rocks are heated to extreme temperatures.
continents move.
Earth's magnetic field reverses direction.
iron particles within the rock align with Earth's magnetic field.
Answers
Explanation
Iron partials are the only thing on earth that is magnetic or the core but the core does not switch direction.
Rocks become magnetic when ; ( D ) Iron particles within the rock align with Earth's magnetic field.
The magnetic components of the earth are the iron particles which are components of a rock and the Earth's core which is an in-movable part of the earth's crust.
Therefore for a rock to become magnetic its iron particles have to come in contact/ align with the magnetic field within the Earth.
Heating up the rocks will increase its' temperature and increase the possibility of producing molten magma and not making the rock magnetic.
Hence In Conclusion Rocks become magnetic when iron particles within the rock align with Earth's magnetic field.

Answer:b it gets warmer
Explanation: from the surface of the object holding the drink then transfers through the liquid by convection. ... This causes the molecules in the food to vibrate rapidly and produce thermal energy (heat)
Option B is correct
When a cold drink sits in a hot room, it gets warmer
Convection is the transfer of heat energy as a result of molecular movement through a fluid.
When a cold drink sits in a hot room:
Heat energy is transferred from the room to the drink
The temperature of the cold drink reduces
The cold drink becomes warmer due to the heat energy received from the cold room
Therefore:

The Sun is exactly 1 AU from the earth. However it is not the biggest star. It's not the hottest star. How come it's the most visible to us? That's because it's just the closest to earth.

Scientists are studying fertilizers to help grass grow in southern California. Fertilizer is any substance that can be added to soil to help plants grow in it. In other words, fertilizer makes soil more fertile. The scientists set up different plots of land that all use the same type of soil and grass seed, but they use different types of fertilizer in each plot. Scientists then measure the grass growth in the different soils over time.
How should scientists set up the control group in this experiment?
A - a plot with grass seed but no fertilizer in the soil
B - a plot with grass seed and many types of fertilizer in the soil
C - a plot without any grass seed or any fertilizer in the soil

(it doesn't have the right subject so i picked something that deals with science)
Answers
Answer:
New Moon
Explanation:
Spring tides occur during new moons when the Sun and the moon are aligned, Pulling together creating big tides.
The phases of moon that results in the spring tide has been the new moon phase and the full moon phase.
What are phases of the moon?The phases of the moon have been given as the shape of the moon visible from the earth. The rotation of the earth, and the revolution of the moon around the earth, results in eight different phases of the moon.
The spring tide has been the force of attraction experienced by the ocean and the drastic oceanic waves with the moon.
When the moon has been in its new moon phase, that is not visible or full moon shape that is completely in between the earth and the sun results in the high pulling force experienced by the oceans, and thereby the spring tides.
Thus, the spring tides occur when the moon has been present ion the new or full moon phase. Thus, option A is correct.

You and your friend live in different states and plant identical hydrangea bulbs in your garden. When they bloom, you send each other pictures. You notice that even though you bought the exact same kind of plant, your hydrangea flowers are blue and your friends are pink! On a hunch, you each measure the pH of your soil and find that your soil is a little acidic and your friends are a little basic. Why do you think the flowers have different colors?
Answers
Answer:
The acid in the soil
Explanation:
The more acid the bluer in terms of hydrangea flowers if there was a balance between the two it will be half and half of the two colors.
Answer:
Since the hydrangeas are changing color depending on whether the soil is acidic or basic, they must have an indicator. This means that any hydrangea planted in acidic soil will have blue flowers and any hydrangea planted in basic soil will have pink. One common indicator present in many plants is anthocyanin, so maybe hydrangeas contain that chemical.

Theory of Plate Tectonics
1 Earth is not like the other planets in the solar system. Earth has layers, much like an onion. These layers provide answers to many questions. Earth's crust, the outermost layer, is not entirely one piece. It is broken into sections which resemble a huge jigsaw puzzle. These giant sections are known as plates. They are always on the move, creeping along at a snail's pace. The plates seem to float on top of the mantle, the layer of Earth composed of partially melted rock.
2 Have you ever put together a puzzle? The pieces must fit together perfectly in order to form a picture. Alfred Wegener was a German scientist. Over 100 years ago, he discovered something fascinating about a map of Earth. Wegener realized that the continents seem to fit together like the pieces of a jigsaw puzzle. This giant piece of land was called Pangaea. It existed over 250 million years ago. Over time, Pangaea's tectonic plates slowly drifted apart. These plates in their current positions make our seven continents.
3 Earth's plates are continually being created or recycled. Scientists have studied the ocean floor. They have discovered ridges of mountains along the bottom of the ocean. These ridges form where two plates have started to move apart. Molten rock from the underlying mantle oozes out. Newly formed rock builds up in the space that has been created by the plates' movement. Plate tectonic theory has also helped scientists explain the deep ocean trenches. These deep ocean trenches are areas where plates are being recycled. This can happen where two plates push together. The crust on the edge of one plate is slowly forced under the other. The plate gets pushed back down into Earth's mantle. It will become molten rock again. This type of area is known as a subduction zone. It forms when continental land masses collide with ocean plates, or when two ocean plates collide with each other.
4 On the ocean floor, movement of the plates causes trenches and ridges. Plate movement can do more than that. It can also form mountains on land. When two continental plates push together, there is so much force that the plates buckle. Massive mountain ranges are formed. The friction during crustal movement can sometimes cause earthquakes and tsunamis.
5 The plates on Earth's crust change Earth's surface features in many ways. They had been pieced together in a giant landmass. The plates slowly moved apart to their current locations. The plates will continue to move, forming new rocks and recycling the old. Imagine how a map of Earth might look after another 250 million years of continental drift.

The wave has traveled 32.4 cm in 9 seconds.
O The wave has traveled 97.2 cm in 3 seconds.
O The wave has traveled 97.2 cm in 1 second.
Answers
Answer:
By using the wave speed formula, v=fλ
v = 3(32.4)
= 97.2 cm/s
The wave has travelled 97.2 cm in 1 second.
Answer:
Speed = 32.4 * 3
Speed = 97.2 m/s
so, the wave has traveled 97.2 cm in 1 second.

Si alguna vez tuviste la curiosidad de revisar la etiqueta nutricional de algún elemento o pusiste mucha atención a tus clases de la prepa, tal vez ya estés familiarizado con ellas o al menos con sus nombres ¿Te suenan nombres como Proteínas, Carbohidratos o Grasas? ¡Son biomoléculas
!Empecemos por los carbohidratos o azúcares compuestos de Carbono, Oxígeno e Hidrógeno. De su composición viene su nombre, un átomo de Carbono (C) por cada molécula de agua (H2O), en proporción 1:2:1. Son los más abundantes en los seres vivos y un punto clave a recordar para tu examen de admisión al IPN, es que estas cadenas de carbohidratos tienen diferentes longitudes y que además, se clasifican en monosacáridos,disacáridos y polisacáridos.
Los carbohidratos se utilizan para producir y almacenar energía por las células (glucosa, almidón y glucógeno).
Los monosacáridos, son azúcares simples, de los cuales el más común es la glucosa. Tienen una fórmula de:
CH2O
y suelen contener de tres a siete átomos de Carbono. Éstas biomoléculas, tienen saturados sus carbonos con un hidroxilo (OH) y un Hidrógeno (H).
