Plz will give 26 points ! and be mark as brainliest ! (all answer have to be correct) i need in a test 1. which phrase identifies the standard difference in elevation on a topography map? a. index contour b, contour interval c, scale bar d. topographic symbol 2.which type of evidence do geologist usually study? multiple choice location of earth in outer space waves that move through earth interactions between living things on earth mineral composition of earths layers different rock samples from earths surface the top of a plateau is the highest point in an area. the difference between the top of the plateau and the lowest point in the area is 250 meters. which word describes this 250 meter measurement a elevation b relief c slope d topography which statement describes the damage that result from earthquakes check all that apply amount of damage can be used to determine intensity damage can measured using richter scale the amount of damage increases as magnitude decreases earthquakes that cause maximum damage are not common román numeral are use to rank damage caused by earthquake

1. The "contour interval' identifies the standard difference in elevation on a topography graph. It shows the difference in elevation of highest and lowest points on a topography map.   In topographic map every fifth contour line is drawn, wider than the contour lines, called as contour index.

2. Geologist usually study all the materials that make up the earth. He can focus on different rock samples from earth's surface. the geologist works to understand history of the planet where we live on, to predict the future by explaining current occurrences.

3. The difference between the top of the plateau and the lowest point in the area of 250 m measurement is called elevation. Elevation is the highest point in the area.

4. Damage from earthquakes is determined by "Ritcher scale". Seismic waves are the vibrations occurs from earthquakes that can travel through the earth. These vibrations can be detected by the Ritcher scale.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

a is the best answer your welcome
