Blingo Review Part I

Review #1

List the 4 branches of Earth Science and describe what each studies.

Answer #1

Geology= study of earthMeteorology= study of weatherAstronomy= study of all objects in spaceOceanography= study of the oceans

Review #2

List the 4 spheres and describe each.

Answer #2

Geosphere= layer that contains core, mantle, crust

Hydrosphere= layer that contains waterAtmosphere= layer that contains breathable

airBiosphere= layer that contains all life

Questions 3

3. What is the difference between physical geology and historical geology?

Answer #3

Physical Geology studies that size, shape, texture, and appearance of rocks and formations on earth

Historical Geology= study of the past history of the Earth

Question 4

List three processes that add carbon to the atmosphere.

Answer 4

Combustion of fossil fuelsBurning of ForestsRespiration from living thingsMelting of permafrostVolcanic eruptionsWeathering

Q5

What type of technology combines the use of satellite information in three dimensions?

A5

Global Position Systems or GPS

Q6

List the three types of rock and describe how each are formed in the rock cycle.

A6

Igneous=cooled magma, extrusive outside, intrusive inside

Sedimentary= rock formed from eroded and weathered rock

Metamorphic=rock that has been pressurized by heat and pressure

Q7

7. What powers the rock cycle?

A7

Heat from the center of the Earth creates igneous rock and forces it to the surface, heat also pressurizes metamorphic

Q8

8. How are fossils found in sedimentary rock useful?

A8

Index fossils are used because they are only found in certain time periods and are used to date rocks.

Q9

9. What is continental drift? List three pieces of evidence for continental drift.

A9

Continental drift is the slow movement of the continents as they float on the liquid mantle…..

EVIDENCE1. The fossil glosspteris2. Ice found in Africa3. The same mountains in Europe and

America

Q10

10. List the three types of plate boundaries and the landforms or geologic processes that can occur at each.

A10

Divergent: moves apart, mid-ocean ridge, rift zone

Convergent: come together, mountains, subduction, explosive volcanoes

Transform: sliding, faults, earthquakes

Q11

11. Compare and contrast relative and absolute dating.

A11

Relative Dating: Compares relative positions of rocks using three principles:

Superposition: Layer on top youngest Crosscutting Principle: Faults or intrusion cutting

through rock is youngest Original Horizontality: all rock laid down horizontally at

first, -unconformities : Gap in the rock record

Radioactive Dating: Uses the percentage of a remaining isotope of carbon 14 or uranium 238 to find the age of rock… scientists must know the half life to do the calculations.

Q12

What is uniformitarianism?

A12

What happened in the past happened today… the same processes that made the earth are at work today shaping our planet.

Q13

What is radioactive dating and how is it used?

Q14

List the 4 types of fossils and describe them….

A14

Molds and castes(3d preservation)Preserved specimens(hair and skin present)Trace fossils(footprints and markings)Carbon film(black film imprint)

Q15

Age of the Earth?

Age of the Universe?

Existence of humans?

Existance of Animals?

A15

Age of the Earth?4.6 billion years

Age of the Universe?14 billion yearsExistence of humans?2 million yearsExistance of Animals?500 million years

Q16

List the main Eras and how long they lasted

Q 23: Describe How scientists measure a star’s brightness

A stars brightness is either called its absolute MAGNITUDE or it apparent MAGNITUDE.

It is measured on a scale of -10 to +10. -10 is the BRIGHTEST.

A16

Precambrian: 2 bya to 600 myaPaleozoic: 600 mya to 200 myaMesozoic: 200 mya to 65 myaCenozoic: 65 mya to present

A17

Compare and Contrast Jovian and Terrestrial Planets

Q17

Terrestrial Jovian

Mercury, Venus, Earth, Mars Jupiter, Saturn, Uranus, Neptune

Rocky, dense, small Gases, light, large

Few moons Many moons

No rings Each has rings

Q18

What is the Nebular theory….

A18

The idea that our solar system formed from a disk of gas and dust called a nebula, gaseous planets formed in a cold zone for away from the sun, and rocky planets formed in a hot zone close to the sun.

Q 19 What are the three types of galaxies

A 19:

SpiralEllipticalIrregular

Q 20: What is Hubble’s Law

This law states that the universe is expanding, and at one time must have formed from a large explosion called the “Big Bang”

Q 21: List the three main types of stars and their temperatures

Red: coolYellow: MediumBlue: hottest

Q 22: Distance is measured in space with:

Light years

1 light year equals around 6 trillion miles.

Q 24: How are stars organized on the HR diagram

Supergiants: Largest stars, often brightestWhite Dwarfs: Tiny, hot, and dimMain-Sequence Stars: 90% of all stars are

Main sequence

Q 25: Describe the life cycle of a star

1. Star Birth: Protostar reaches a temperature hot enough for nuclear fusion to begin

2. Main sequence: 90% of a stars life is contain in this stable stage

3. All stars run out of fuel and collapse4. Most stars(our Sun) go through a red giant

phase when they first run out 0f fuel.4. The largest stars have such a strong

gravitational pull when they collapse that they become BLACK HOLES
