Answer 0

Metamorphic
Sedimentary
Igneous

Question 1

What are the four eras

Answer 1

Cenozoic
Mesozoic
Paleozoic
Precambrian

Question 2

What is metamorphism

Answer 2

Rock changing from igneous or sedimentary rock to metamorphic rock by heat and pressure

Question 3

What is the difference between weather and climate

Answer 3

Climate is long term

Weather is short term

Question 4

What are the 3 plate boundaries and their definitions

Answer 4

Convergent - Plates colliding
Divergent - Plates moving apart
Transform - plates moving parallel

Question 5

How are glaciers formed?

Answer 5

Dozens of delicate ice crystals being pressed into each other

Question 6

What enabled glaciers to be such an erosional force

Answer 6

Moving glaciers pick up rock debris and it interacts with the ground below by eroding it

Question 7

What is the albedo affect?

Answer 7

When glaciers reflect heat and light into the atmosphere

Question 8

What is an erosional process and the definitions of its parts

Answer 8

Breaking of rocks into sediments by
Weathering (Breaking up of rocks by wind, rocks, ice, etc.)
Erosion (Movement of rock)
Deposition (Laying down of rock)

Question 9

What are the 7 landform regions

Answer 9

Western Cordillera
Interior Planes
Innuitian Mountains
Hudson's bay lowlands - Arctic Lowlands
Great lakes - St. Lawrence Lowlands
Canadian Shield
Appalachians

Question 10

What are the 7 factors that contribute to climate?

hi evy

Answer 10

Jet streams
Bodies of water
Ocean Currents
Wind and air masses
Latitude
Elevation
Relief

Question 11

What is the climate region that we live in?

Answer 11

Lower lakes

Question 12

What is the continental drift theory

Answer 12

People thought that once all of the continents were part of a super continents called Pangea. Eventually this super continent drifted apart and formed several different land masses.

Question 13

What is the plate tectonic theory

Answer 13

Earth’s outer shell is made out of 20 plates that float on a layer of the Earth’s Magma. Convectional currents inside move the plates.

Question 14

What are trenches and what are ridges

Answer 14

Ridges - Erosion of rivers by tectonic plates moving closer to each other
Trenches - Created by erosion by rivers and by plate moving away from each other

Question 15

How was lake Iroquois formed?

Answer 15

In a basin of Lake Ontario.

Glaciers melted and retreated and filled up the basin with meltwater

Question 16

What is sedimentary rock

Answer 16

This rock is formed from sediments such as sand, soil, rock particles, and marine animals. Gravity compresses these layers into rock.

Question 17

What is igneous rock

Answer 17

Rock formed by cooling lava

Question 18

What is metamorphic rock

Answer 18

Formed when existing rock changes into different rock by heat and pressure

Question 19

What is isostatic rebound

Answer 19

When Earth gets pushed down by ice. Over time it gets pressed back up, like memory foam.

Question 20

What is archipelago

Answer 20

A group of islands

Question 21

What is Maritime climate and what is continental climate

Answer 21

Continental - Extreme temperatures, not a lot of rain and snow
Maritime - Mild temperatures, a lot of rain and snow

Question 22

What do the blue and white bars on a climate graph mean?

Answer 22

Average rainfall in mm

Average snowfall in mm

Question 23

10mm of snow is the water equivalent of ____mm of rain

Answer 23

1mm

Question 24

The growing season is the portion of the year when average daily temperatures remain above ______ degrees Celsius

Answer 24

5.6 degrees

Question 25

Why are most Earthquakes and Volcanoes located along plate boundaries?

Answer 25

That’s where the most interactions with the Earth happen. The moving plates push the land up and form these.
