Mid term science questions

a rocket engine on the satellite may be used to help place the satellite into the correct orbit. Once in orbit, satellites do not need any rockets to keep them moving. However, small rockets called thrusters are used if a satellite needs to change orbit slightly.

How are rockets and artificial satellites used?

Over the course of history, man has developed amazing technology to help us see beyond our own planet into the vastness of our galaxy and even way beyond.

How can exploring space help scientist learn about Earth?

When using on iPhones or computers and with satellites

How can modern technology be used in mapmaking?

They give you direction of the place or places you need to go

How do maps help determine location

Laws differ from scientific theories in that they do not posit a mechanism or explanation of phenomena: they are merely distillations of the results of repeated observation. As such, a law is limited in applicability to circumstances resembling those already observed, and may be found false when extrapolated.

How do scientific law and scientific inquiry differ

Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes - the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

How do scientists use the electromagnetic spectrum to study the universe?

The sun's gravity also produces tides. But since the forces are smaller, as compared to the moon, the effects are greatly decreased. Tides are not caused by the direct pull of the moon's gravity. The moon is pulling upwards on the water while the earth is pulling downward.

How do the Moon and the Sun affect Earth's oceans?

Use the degree symbol instead of "d". Use periods as decimals, not commas. ... List your latitude coordinates before longitude coordinates. Check that the first number in your latitude coordinate is between -90 and 90.

How do you use line of latitude and longitude

As the Earth rotates, it also moves, or revolves, around the Sun. The Earth's path around the Sun is called its orbit. It takes the Earth one year, or 365 1/4 days, to completely orbit the Sun. As the Earth orbits the Sun, the Moon orbits the Earth.

How does Earth move?

The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still.

How does the Moon move around Earth?

Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere.

What are Earth's major systems and how do they interact?

NASA will open up the space frontier, and bring back knowledge and experience that will shape our future endeavors. Specifically, major science-based exploration goals include: ... The capabilities we are developing will open a broad range of exciting destinations for human exploration in the solar system

What are goals for future space exploration?

Robatic arms , braces

What are some ways that people use technology to improve life on Earth?

the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust.

What are the interior layers of Earth?

Topographic maps also have a vertical scale to allow the determination of a point in three dimensional space.

What can a topographic map tell you

water and carbon dioxide

What conditions are required for the existence of life on Earth?

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra. This can occur only when the sun, Earth, and moon are aligned exactly, or very closely so, with the Earth in the middle.

What is a lunar eclipse?

A solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks the Sun.

What is a solar eclipse?

To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list. Range can also mean all the output values of a function. See: Range of a function. The Range

What is mean mode median and range

In the philosophy of science, models of scientific inquiry have two functions: first, to provide a descriptive account of how scientific inquiry is carried out in practice, and second,

What is scientific inquiry

A fact is a statement that can be proven true or false. An opinion is an expression of a person's feelings that cannot be proven. Opinions can be based on facts or emotions and sometimes they are meant to deliberately mislead others.

What is the difference between a fact an opinion

Hubble Space Telescope / NASA, ESA / 1990 / Visible, UV, Near-IR / Deep Space Objects. Chandra X-ray Observatory / NASA / 1999 / X-ray / Various. Spitzer Space Telescope

What types of telescopes are used to explore space?

Crwed to see if humans can survive and uncrewed to collect information

Why do scientists send both crewed and non-crewed missions into space?

The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun.

Why do the seasons change as Earth moves around the Sun?

he half of the Moon that points toward the Sun looks bright because it is lit by sunlight. The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. When the Moon is between Earth and the Sun, the lit side is hidden from us.

Why does the Moon's appearance change?

There are several factors that influence the amount of sunshine received at various places on the earth. The major factor is that while the sun is overhead at the equator, it is at a rather slant angle at the poles. This effect can be demonstrated using a torch, which can be taken as the sun.

Why is Earth warmer at the equator and colder at the poles?
