How do you read the stars?

Stars are represented as black dots on a white background, which makes it easier to read when observing at night. The size of the dot reflects the brightness of the star, the bigger the dot, the brighter the star.

What does blue on a map represent?

The color brown is used to denote most contour lines on a map, which are relief features and elevations. Topographic maps use green to denote vegetation such as woods, while blue is used to denote water features like lakes, swamps, rivers, and drainage.

What does small star Mean map?

A legend is necessary for most maps because cartographers cannot write everything into the map, so they need symbols. The symbols require a key to understand them. The star symbol, ★, is next to Washington DC on the map. A star, ★ , usually means a country capital on a map.

Which type of wave vibrates from side to side and up and down?

S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side. S waves are called secondary waves because they always arrive after P waves at seismic recording stations.

What causes an earthquake by Brainly?

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

How do I read the stars?

Start with the Big Dipper. It's your starting point to the map to the universe. Look high in the northern sky for a gently arcing line of three stars connected to a shallow pan. Follow the path of the two stars that make up the far edge of the Big Dipper's pan up to the first bright star.

How does a star chart work?

The center of the chart shows stars that are directly overhead. The outer rim represents the horizon, labeled with the directions north, south, east and west. To match the sky, the chart must be held overhead, with the chart's north marker pointing north. And it has to be a chart that was made for the month you're in.

How does a star map work?

How do star maps work? It's based on a simple, magical idea – you enter a date, a place and a time into our configurator and watch as we calculate the stars visible at that precise moment.

What does green represent on a map?

Physical maps use color most dramatically to show changes in elevation. A palette of greens often displays elevations. Dark green usually represents low-lying land, with lighter shades of green used for higher elevations. In the next higher elevations, physical maps often use a palette of light brown to dark brown.

What does brown represent on a map?

What are the 5 colors on a map?

Blue: lakes, rivers, streams, oceans, reservoirs, highways, and local borders. Red: major highways, roads, urban areas, airports, special-interest sites, military sites, place names, buildings, and borders. Yellow: built-up or urban areas. Green: parks, golf courses, reservations, forest, orchards, and highways.

What is the definition of seismic waves in science?

A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth's surface (Rayleigh and Love waves) or through the earth's interior (P and S waves).

How is the particle displacement related to the direction of wave movement in a longitudinal wave?

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.

What is the Pacific Ring of Fire It is an area circling the Pacific Ocean?

The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire.

What factors affect the earthquake and volcanic activity distribution in the lithosphere?

Most volcanoes and earthquakes are caused by the motion and inter- action of Earth's plates. here, Earth's plates are in contact with one another and can slide beneath each other. The way Earth's plates interact at boundaries is an important factor in the locations of earthquakes and volcanoes.

What does blue represent on a map?

water features The color brown is used to denote most contour lines on a map, which are relief features and elevations. Topographic maps use green to denote vegetation such as woods, while blue is used to denote water features like lakes, swamps, rivers, and drainage.

What does white represent on a map?

White: Sparse or no vegetation. Basically, it indicates any landscape feature except for trees or water, including desert, grass, sand, rocks, boulders, and so on. Purple: Revisions that have been made to a map using aerial photos. The USGS no longer does this, but existing maps might have purple revisions.

What does green indicate in a map?

Yellow colour is used in topographical maps to represent fields of crops, arable lands or agricultural lands. It is the colour that shows areas under cultivation by man.

What is earthquake Wikipedia?

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

How do rock particles move during the passage of AP wave through the rock?

Particles of rock move forward and back during the passage of the P waves. Primary waves can travel through both fluids and solids. Secondary waves travel slower and follow primary waves, propagating as shear waves. Particles of rock move from side to side during the passage of S waves.

How is the particle displacement related to the direction of wave movement in a longitudinal wave perpendicular Toparallel Toopposite Toabove?

The displacement of particles is perpendicular to the direction of wave motion. What happens to particles in a surface wave (such as a water wave)? They move perpendicular and parallel to the direction of wave motion.
