activity 4

What is the atmosphere ? the layer of air that surrounds Earth
What is made of ? Earth's is made of air
What are the different layers of the atmosphere ? EXOSPHERE (300 KM to more than 600 km )

• Many satellites orbit here


• Air pressure is lowest here


• temperature goes up as altitude increases

THERMOSPHERE (90 km to 300 km)

• shimmering curtains of light called auroras happen here.


• air pressure is lower than mesosphere.


• temperature goes up as altitude increases.

MESOSPHERE (50 km to 90 km)

• meteors , or "shoting satars" , burn up here.


• air pressure is lower than stratosphere.


• temperature goes down as altitude increases. this is coldest layer of the atmosphere.

STRATOSPHERE (16 km to 50 km)

• jets cruise near the bottom of this layer.


• air pressure is lower than troposphere.


• temperature goes up as altitude increases.

TROPOSPHERE (0 km to 16)

• all weather happens here.


• air pressure is highest in this layer.


• temperature goes down as altitude increases.

why is it important for us to take care of our precious atmosphere?

because is important for two main reasons. it is the air that you breathe so , no atmosphere , no breathing.the other reason is ot protects you by burning up the meteroids that could hit earth.

activity 2

What is weathering ? the process of bing broken apart by wind , water , ice , and living things

What is erosion ? the process of moving rock form place to place

What is deposition ? the process of building up the surface of

Earth by putting down rock

Where have you observed erosion , weathering and deposition ? the erosion is of volcanoes , weathering is the wearing away of rock. for example , water in a river makes rocks bang against each other , breaking pieces off. I saw weathering when the river, heat and wind break the rocks apart. I saw erosion when a river in Mexico carries the little rocks from one part of the river to another part. I was depostion when the rocks dropped in the water.

What do you these site have in common ? weathering the rocks down the water and stop because is sand so the deposition goes into the river the rocks so in the sand stop and the erosion the rocks moves from place to place.

activiti 1 rock cycle

Rocks are the most common material on Earth. They are naturally occurring aggregates of one or moreminerals.



Rock divisions occur in three major families based on how they formed: igneous, sedimentary, and metamorphic. Each group contains a collection of rock types that differ from each other on the basis of the size, shape, and arrangement of mineral grains.
The rock cycle is an illustration that is used to explain how the three rock types are related to each other and how Earth processes change a rock from one type to another through geologic time. Plate tectonic movement is responsible for the recycling of rock materials and is the driving force of the rock cycle
IGNEOUS ROCK -the kind of rock that forms when magma cools.
SEDIMENTARY ROCK-the kind of rock made when small pieces of rock, shell, and bone are squeezed together.
METAMORPHIC ROCK-the kind of rock that has been changed by heat and pressure.
THE ROCK CYCLE-a cycle is a pattern of events that occurs over end over.
THE ROCK CYCLE -is a pattern of the events that change rock

activity 3

What is the water cycle ? water moves around Eatrh in a constant cycle. In the atmosphere , clouds are made of tiny drops of water or pieces of ice. precipitation from clouds falls on the land and into rivers , lakes , and oceans.

Can you make your own diagram of the water cycle ?

What is so interesting about the water cycle ? the interesting is that in the clouds is the condensation star to rain is called precipitation the next go to the montains and there star the evaporation this is the interesting.

What have you observed about the weather in houston ? it is warm in rain is clima is tropical
