Unit 5 Landforms

Question 1

Convection

Answer 1

Heat transfer in fluids (liquid and gases) where warmer,less dense fluid rises, allowing colder denser fluid to take its place;cause a tumbling motion in the fluid

Question 2

Convergent boundary

Answer 2

A plate boundary formed when two tectonics plates move toward one another perpendicular to a fault line

Question 3

Crust

Answer 3

Earth’s outermost layer; the hard rock layer of the planet that make up the continent and holds the ocean

Question 4

Divergent boundary

Answer 4

A plate boundary formed when two tectonic plates move apart from one another perpendicular to the fault line

Question 5

Erosion

Answer 5

The transport of sediment by wind water or gravity

Question 6

Fossil

Answer 6

The remain of ancient animals or plants,the trace or impression of living thing from past geologic ages or the traces of their activity

Question 7

Fossil record

Answer 7

Include all of the fossils that have ever been found; scientist uses it to understand earths history

Question 8

Geologic column

Answer 8

The rock layers and the fossil found in them

Question 9

Igneous rock

Answer 9

A category of rock formed when hot liquid rock (either magma or lava) calls into solid form

Question 10

Index fossil

Answer 10

Certain fossil known to exist in a particular place and time that may be use to determine the relative age of rocks or other fossils

Question 11

Inner core

Answer 11

The hottest layer inside earth; made of a mixture of solid iron and nickel

Question 12

Mantle

Answer 12

The layer of Earth between the outer core and the crust ; mostly molten, semi-solid rock called magma that is so soft it moves in convection current like liquid water

Question 13

Metamorphic rock

Answer 13

A category of rock formed by chemical reactions where one type of rock is changed by pressure or heat into a new type of rock with different properties

Question 14

Numeric age

Answer 14

A precise number ( in year minutes or other unit of time) that represent how much time has passed

Question 15

Outer core

Answer 15

The outer layer of earths core ; made of liquid iron and nickel metal

Question 16

Relative age

Answer 16

Tells scientists whether something is younger or older than something else

Question 17

Rock

Answer 17

A mixture of mineral that heat and pressured have pressed together

Question 18

Rock cycle

Answer 18

The processes that form, break down, and reform rock from one category to another

Question 19

Sedimentary rock

Answer 19

A category of rock formed from layers of sand soil clay gravel and other sediments that built up in one location over time

Question 20

Tectonic plates

Answer 20

Drifting slabs of rock called plates that make up earth surface

Question 21

Transform plate boundary

Answer 21

A plate boundary formed when two tectonic plates slide past each other in a parallel grinding along their sides as they move

Question 22

Weathering

Answer 22

The breakdown of rocks into smaller pieces from exposure to Change in temperature wind water and/or biological forces
