1. What kind of landform does this map show: an island, a mountain range, a valley, or a plateau? Explain your answer.
Plateaus are discovered on every continent as well as cover one-third of the Earth's land surface. Plateau is the kind of landform this map show.
What is landform?Landforms were natural planetary structures that contribute to the landscape of a planet. Terrain, commonly known as "relief," is the planet's third (vertical) dimension. The most fundamental landforms are continents and oceans.
A plateau is a flat, high landform with at least one side that rises abruptly above the surrounding surroundings. Plateaus are discovered on every continent as well as cover one-third of the Earth's land surface. Together with mountains, plains, as well as hills, they are one of the four primary landforms. Plateau is the kind of landform this map show.
Therefore, plateau is the kind of landform this map show.

2. What is the contour interval? (Remember: The unit for this map is feet.)
The contour interval is the elevation difference between two consecutive contours. For a map, it is always kept the same or constant. The contour interval is 400 feet.
What is the contour interval?A contour interval is the vertical distance or elevation difference between contour lines. Index contours are thicker or more prominent lines that appear every fifth contour line.
If the numbers associated with specific contour lines increase, so does the elevation of the terrain.
A contour interval is the difference in elevation between two contour lines. For any given map, it is always the same. Contours are represented by lines. Contour lines that are closely spaced indicate steep slopes.
Thus, The contour interval is the elevation difference between two consecutive contours. For a map, it is always kept the same or constant.

During which moon phase do spring tides occur?
new moon and full moon
first quarter and third quarter
waxing gibbous and waning gibbous
waxing crescent and waning crescent
(it doesn't have the right subject so i picked something that deals with science)
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?
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.

Explanation:
Marco is conducting an experiment. He knows the wave that he is working with has a wavelength of 32.4 cm. If he
measures the frequency as 3 hertz, which statement about the wave is accurate?
O The wave has traveled 32.4 cm in 3 seconds.
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.
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.

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.
